As students settle into their new school-year routines, it’s a good time to reflect on how their experiences in the classroom affect the Chesapeake Bay.

Today’s students will play a critical role in the health of tomorrow’s Chesapeake. Making sure they understand how to critically think about evolving environmental issues is essential to the long-term success of environmental protection.
While managers are making progress in addressing the issues facing the Bay, many of the remaining challenges to a healthier ecosystem rest in the hands of individuals, businesses and communities. From decisions on how to heat and cool homes to decisions on where to live, what vehicle to drive and what to plant on private properties, individual choices can have a huge impact on the Bay. This mean a successful environmental protection strategy must be built on the collective wisdom of the environment’s residents, informed by targeted environmental education and starting with our youngest students.
In recent years, a clearer picture has emerged about the environmental literacy of our students. A 2008 National Environmental Literacy Assessment and related follow-up studies showed that students who attended schools with environmental education programs knew and cared more about the environment, and were more likely to take actions to protect their environment, than students who didn’t. But learning outdoors during the school day is not common in the United States.

While our society is increasingly disconnected from the natural environment—spending more time online and less time outdoors—there is good news: states are increasingly stepping up to ensure that students have the opportunity to connect with nature. The state of Maryland, for instance, has established the nation’s first graduation requirement for environmental literacy; beginning in 2015, every student that graduates from a school within the state will have participated in a program that will help him or her make more informed decisions about the environment. Several states in the region have established partnerships for children in nature, taking a comprehensive look at how they can better encourage outdoor programs for children. Even more are recognizing the efforts of their schools to become more sustainable, ensuring that more students are learning inside buildings that model sustainable behaviors.
This momentum is being echoed at the regional level. The recently signed Chesapeake Bay Watershed Agreement commits the six watershed states and the District of Columbia to give every student the knowledge and skills necessary to protect and restore their local watershed. The cornerstone of this goal is the Meaningful Watershed Educational Experience, or MWEE, which should occur at least once in each elementary, middle and high school. MWEEs connect standards-based classroom learning with outdoor field investigations to create a deeper understanding of the natural environment. MWEEs ask students to explore environmental issues through sustained, teacher-supported programming. But less intensive outdoor field investigations could occur more frequently—each year when possible.
The Watershed Agreement highlights the roles that state departments of education and local education agencies play in establishing expectations and guidelines for the development and implementation of MWEEs. Indeed, plans that include strategies for MWEE implementation—coupled with outreach and training opportunities for teachers and administrators—have been effective in establishing and supporting a network for environmental literacy.
To support these efforts, funding is available: the National Oceanic and Atmospheric Administration (NOAA) offers grants through the Bay Watershed Education & Training (B-WET) Program, and the Chesapeake Bay Trust offers similar opportunities. The Chesapeake Bay Program also maintains a clearinghouse of teaching resources on Bay Backpack.

Chesapeake Bay Program partners have identified the outcomes they will participate in to achieve the goals of the Chesapeake Bay Watershed Agreement, and have invited individuals and organizations to participate in the development of the Management Strategies that will describe how we will accomplish these outcomes and how we will monitor, assess and report our progress.
"Today marks an important milestone in Bay restoration, as all nine partners have identified the specific Management Strategies they will be… developing… to protect and restore the Chesapeake Bay, its streams and its rivers,” said Joe Gill, Principals’ Staff Committee Chair and Maryland Department of Natural Resources Secretary, in a media release. “Moving forward, we will be engaging citizens in every step of this process.”
Indeed, public input is essential to Management Strategy development: each strategy will include a period for public review and comment before it is adopted. Individuals can keep informed about the development of these Management Strategies in three ways:
Over the Chesapeake Bay Program’s long history, its leaders have learned that collaboration is key to restoration success. In June, the governors of Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia, the mayor of the District of Columbia, the administrator of the U.S. Environmental Protection Agency (EPA) and the chair of the Chesapeake Bay Commission came together to sign the Chesapeake Bay Watershed Agreement. Written with input from individuals, organizations and other partners, this document contains goals and outcomes that will restore and protect the nation’s largest and most productive estuary. But what will the Agreement mean for the residents of this massive watershed? Read our list to find out.
10. Improved access to the water. From fishing piers to boat launches, people in the watershed want more access to rivers, streams and the Bay. And while partners have opened 69 new access sites over the last three years, access remains limited, with consequences for tourism economies and environmental conservation. Bay Program partners have set a goal to open 300 new public access sites across the watershed by 2025. Learn more.
9. New opportunities to fish in headwater streams. Our increasing need for land and resources has fragmented our rivers and streams, harming the health of those fish that must migrate through unobstructed waters to reach their spawning grounds each spring. Bay Program partners plan to improve stream health and restore fish passage to the Bay’s headwaters, opening up habitat to migratory fish like alewife, American shad and brook trout. More habitat can mean more fish, and more fish can mean more fishing opportunities. Learn more.

8. Cleaner waters. Nutrient and sediment pollution are behind the Bay’s biggest health problems. Nutrients fuel the growth of harmful algae blooms, which create low-oxygen dead zones that suffocate marine life. Suspended sediment blocks sunlight from reaching underwater plants. Bay Program partners plan to work under the Bay’s existing “pollution diet” to reduce nutrient and sediment pollution, improve water quality, and support the living resources of the Bay, its rivers and its streams. Learn more.
7. Safer waters. Almost three-quarters of the Bay’s tidal waters are considered impaired by chemical contaminants. These substances can harm the health of humans and wildlife, and have been linked to tumor growth in fish, eggshell thinning in birds and intersex conditions in amphibians. Bay Program partners are committed to reducing toxic contaminants in our waters, with a focus on mercury, PCBs and contaminants of emerging and widespread concern. Learn more.
6. Healthy waters that remain that way. Healthy watersheds provide us with clean water, critical habitat and economic benefits. While there are a number of healthy watersheds in the region, development poses a constant threat. Bay Program partners want 100 percent of state-identified healthy waters and watersheds to remain that way. Learn more.
5. A larger community of citizen stewards. The success of our restoration work will depend on local action, and local action will depend on local stewards. Bay Program partners hope to build a larger, broader and more diverse community of citizen stewards who will carry out the conservation and restoration activities that will benefit their local communities and the Bay. Learn more.

4. Sustainable seafood. Habitat loss, invasive species, poor water quality and harvest pressure threaten the sustainability of the Bay’s recreational and commercial fisheries. But Bay Program partners have committed to using sound science and responsible management to increase fish and shellfish habitat and populations, leading to more striped bass, blue crabs and oysters in the Bay and on the market. Learn more.
3. Smarter growth. With the largest land-to-water ratio of any estuary in the world, it is clear that what happens on land has a direct impact on water quality in the Bay. But stormwater runoff continues to push polluted rainwater over streets and sidewalks and into storm drains, rivers and streams. Bay Program partners plan to help local governments control polluted runoff, conserve valuable wetlands, farms and forests, and reduce the rate of land that is lost to paved roads and parking lots. Learn more.

2. More knowledge and skills to help save our watershed. It is often said that people value what they know and protect what they value. This means that a boost in environmental education now could create a vital foundation for environmental stewards of the future. Bay Program partners will work to enable area students to graduate with the knowledge, skills and meaningful experience needed to protect and restore their local watershed. Learn more.
1. Communities that are resilient to climate change. The impacts of climate change—rising seas, warming waters, extreme weather, ocean acidification—are happening now. To withstand these impacts, we must improve our natural and built infrastructure. Bay Program partners have set a goal to increase the climate resiliency of the watershed’s resources, habitats and communities using monitoring, assessment and adaptation. Learn more.

The Chesapeake Executive Council signed the Chesapeake Bay Watershed Agreement today, recommitting Chesapeake Bay Program partners to restoring, conserving and protecting the Bay, its tributaries and the lands around them.
Agreement signatories include the governors of Maryland, Virginia, Pennsylvania, New York, West Virginia and Delaware; the mayor of the District of Columbia; the chair of the Chesapeake Bay Commission; and the administrator of the U.S. Environmental Protection Agency (EPA) on behalf of the Federal Leadership Committee for the Chesapeake Bay. This marks the first time that the Bay’s headwater states of New York, West Virginia and Delaware have pledged to work toward those restoration goals that reach beyond water quality, making them full partners in the Bay Program’s watershed-wide work.
“Today we celebrate the most inclusive, collaborative, goal-oriented Agreement the Chesapeake Bay watershed has ever seen, highlighted by unprecedented participation from the headwater states and the public,” said Chesapeake Executive Council Chair and Maryland Gov. Martin O’Malley in a media release. “This Agreement not only addresses our continuing water quality and land use challenges, it also confronts critical emerging issues—environmental literacy, toxic contaminants and climate change. Finally, it builds upon the strength of our diverse citizenry, calling to action the nearly 18 million people that call our watershed home. Together, we can and will achieve our united vision of a healthy Bay and a productive watershed, cared for by engaged citizens at every level.”

Years in the making, the Agreement contains 10 goals and 29 measurable, time-bound outcomes that will help create a healthy watershed. They will lower nutrient and sediment pollution; ensure our waters are free of toxic contaminants; sustain blue crabs, oysters and forage fish; restore wetlands, underwater grass beds and other habitats; conserve farmland and forests; boost public access to and education about the environment; and increase the climate resiliency of the watershed’s resources, habitats and human communities.
Public input had a direct impact on the content of the Agreement—encouraging partners to include goals related to environmental stewardship, toxic contaminants and climate change—and will continue to contribute to how the Agreement is achieved. Indeed, partners plan to work with universities, local governments, watershed groups, businesses and citizens in creating the management strategies that will define how we will accomplish the Agreement’s outcomes and goals.

In addition to signing the Chesapeake Bay Watershed Agreement, Executive Council members heard from the Bay Program’s three advisory committees, which represent citizens, local governments and scientific and technical interests from across the watershed. Executive Council members also heard from four high school students representing Maryland, Virginia, Pennsylvania and the District of Columbia. While each of these students was introduced to conservation in a different way, they have all had valuable experiences on the Bay and spoke about the importance of engaging future generations in environmental restoration, advocacy and leadership.
For the past two and a half years, the Chesapeake Bay Program has been working on a new Chesapeake Bay Watershed Agreement, an accord that will guide the collaborative restoration and conservation efforts of the six states and the District of Columbia in the 64,000 square mile network of land and waters that drains to the Chesapeake. Meaningful public review and input has proven critical to this process.

The first opportunity to gain public input occurred in July 2013, when the agreement’s framework was put out for public review. Interested parties were able to submit comments in writing, through our website and during a public meeting; through these channels, representatives of various organizations asked questions or expressed their views on various topics of discussion. This level of transparency and inclusiveness is characteristic of the manner in which the Bay Program conducts its affairs.
In addition to these opportunities, the Bay Program’s staff and leadership engaged in numerous outreach activities, addressing advisory committees, watershed organizations and local communities to ensure they were aware of this effort and could participate in a meaningful and informed way. A second opportunity for formal public comment was provided this past February on a more substantive draft agreement. In all, more than 2,400 comments were received from throughout the watershed. Each comment was reviewed, evaluated and taken into account during the decision-making process. Each step in this process was open and transparent, and summaries of all comments and how they were responded to were made available.

Transparency and accountability have been themes throughout the development of the new agreement. And we will continue our efforts to be open and accountable as we move into the next steps of our efforts—the development of Management Strategies, an important new component of this agreement. These strategies will serve as written documentation for how we intend to achieve our goals and outcomes, and will be developed by our Goal Implementation Teams. Once a draft Management Strategy is developed, a public notice will be issued and an opportunity for public input will be provided. As before, this input will be used to consider making changes to the Management Strategies before they are finalized for implementation.
Management Strategies will specify exactly what each of the Bay Program partners will contribute, how they will address impacts associated with climate change, what resources and information they will bring to the table, how they will interact and engage communities and involve local governments, and how they will use the adaptive management process to review indicators and monitoring data and make well-documented, science-based decisions. The partnership’s Science and Technical Advisory Committee will assist the Goal Implementation Teams in developing new indicators and performance metrics to ensure they are collecting appropriate data and information to measure progress toward their outcomes and to make warranted adjustments, if necessary.
Each of these Management Strategies will be reviewed and evaluated on a biennial basis. The two-year reviews will be presented to the partnership’s governance structure for discussion and feedback. All of the Management Strategies and two-year reviews will be publicly available so progress toward the agreement’s goals and outcomes can be tracked. This level of transparency and accountability, as well as public engagement and outreach, is unprecedented in any previous agreements intended to guide the Bay restoration effort.

In my 25-year career in public service, I have not witnessed a more genuine effort to solicit public input and to give that input serious consideration. That input resulted in significant improvements in the Chesapeake Bay Watershed Agreement. Goals and outcomes that were not included or previously rejected were reconsidered and inserted in the new agreement as a direct result of public input. Not every comment was addressed in exactly the way it was submitted; but every comment did get deliberate consideration and was addressed in some manner by the partnership’s leadership, which includes many secretaries of state environmental agencies, federal agency representatives and leaders of non-governmental and advisory groups. In the end, the final agreement is a much clearer, stronger and more comprehensive document because of the input we received from concerned and engaged citizens throughout the watershed.
This “next generation” agreement will guide restoration of the Bay watershed and ecosystem in the decades ahead. Implementation of the new agreement will continue to be influenced and shaped by the interests, knowledge and expertise of every individual, organization, community, local government, business and partner that is willing to engage and be involved in this endeavor. On behalf of the entire Bay Program, I want to express our genuine gratitude for taking the time and making the effort to share your thoughts, concerns and suggestions with us on the new Chesapeake Bay Watershed Agreement. It made a very distinct and significant difference in the outcome.

Climate change and chemical contaminants were among the leading issues addressed. More than 1,000 individuals asked the Bay Program to integrate climate concerns and adaptation strategies into our work, while more than 300 asked us to set goals to reduce the pesticides, pharmaceuticals and other toxic contaminants in our rivers and streams. Residents from across the watershed submitted letters that described the potential effects of both issues, from rising water temperatures and eroding shorelines to intersex fish and human health impacts.
Other comments on the draft agreement addressed the need to control stormwater runoff in urban and suburban areas, increase the environmental education of the region’s students and establish more public access sites to connect citizens with local waterways.
“The Chesapeake Bay Program values citizen input,” said Joe Gill, chair of the Bay Program’s Principals’ Staff Committee and secretary of the Maryland Department of Natural Resources (DNR). “More than 17 million people live in this watershed. One of the most important lessons we have learned in our decades of restoration work is that individual citizens, private businesses, watershed groups and local governments are our stakeholders—they are people who have a “stake” in what we do. They are key partners in the attainment of our restoration goals. The Executive Council will welcome and consider all of the comments we receive from our stakeholders when finalizing the new agreement.”
The Chesapeake Bay Watershed Agreement will guide signatories—which include the states of Maryland, Virginia, Pennsylvania, New York, West Virginia and Delaware; the District of Columbia; the Chesapeake Bay Commission; and the U.S. Environmental Protection Agency—in the restoration of the watershed. It establishes goals and outcomes that address water quality, fisheries and habitat, land conservation, public access and environmental literacy.
Comments on the draft agreement were left between January 29 and March 17 by private citizens, nonprofit organizations, conservation districts, wastewater agencies and more. A previous comment period on a prior draft took place between July 10 and August 15, 2013, and generated comments summarized here.
It’s been fourteen years since the last Chesapeake Bay agreement was signed, and much has changed in the decade and a half since Chesapeake 2000 was written. We have learned more about what works and what doesn’t when it comes to conservation. We have improved how we monitor our progress. We are aware of the impacts of climate change, which will make it more difficult for us to achieve our goals. And we have watched an Executive Order and a “pollution diet” be issued, the first directing federal agencies to step up their restoration work and the second calling on states to reduce pollution entering rivers and streams. In this time, we have also recognized the need to revisit our previous Bay agreements and better coordinate our future efforts to efficiently and effectively accomplish our restoration goals.
After countless meetings, discussions and a preliminary public comment period, the Chesapeake Bay Program is now seeking review and comment on a final draft of a new Chesapeake Bay Watershed Agreement. Like past agreements, this one is a result of negotiations and compromise, and will guide the six Bay states and the District of Columbia in their work to create a healthy and vibrant watershed.
This draft agreement is more focused than past versions. It contains seven high-level goals and twenty-two measurable, time-bound outcomes. These will allow our partners—which, for the first time, include West Virginia, New York and Delaware—to focus on top restoration priorities and better measure progress. Indeed, one of the agreement’s most significant improvements is its inclusion of management strategies, which will describe how and when we intend to achieve our outcomes as we engage local communities, develop indicators of success and report on our progress. Management strategies bring an unprecedented level of transparency to our work, and provide a higher level of accountability than previous agreements have done.
But to make this the best agreement possible, we need to hear from you. And we have tried to make the public comment process an easy one: the draft agreement is available here, and we will welcome comments until March 17, 2014. You can offer input at the March 13 meeting of the Management Board or submit an online comment or an email to the Bay Program. Learn more.

The draft Chesapeake Bay Watershed Agreement establishes a series of goals and outcomes that address water quality, fisheries and habitat, land conservation, public access and environmental literacy. Signatories will include the states of Maryland, Virginia, Pennsylvania, New York, West Virginia and Delaware; the District of Columbia; the Chesapeake Bay Commission; and the U.S. Environmental Protection Agency.
By signing the agreement, partners will commit to taking the steps needed to attain a healthy watershed: to lower nutrient and sediment pollution; to sustain blue crabs, oysters and forage fish; to restore wetlands and underwater grass beds; to conserve farmland and forests; and to boost public access to and education about the environment.
“Healthy, sustainable fisheries, plentiful habitats for wildlife, conservation efforts and citizen actions that support clean water and clean air—this is how we create a healthy Bay,” said Bay Program Principals’ Staff Committee Chair and Maryland Department of Natural Resources Secretary Joe Gill in a media release. “Connecting our citizens to these resources through public access and environmental education completes the picture, instilling the personal sense of ownership key to our progress.”
“The goals and outcomes that are outlined in the Chesapeake Bay Watershed Agreement are interrelated: improvements in water quality can mean healthier fish and shellfish; the conservation of land can mean more habitat for wildlife; and a boost in environmental literacy can mean a rise in stewards of the Bay’s resources,” said Bay Program Director Nick DiPasquale. “By signing this agreement, Bay Program partners will acknowledge that our environment is a system and that these goals will support public health and the health of the watershed as a whole.”
The draft is available here. The Bay Program welcomes comments on this draft between January 29 and March 17, 2014. Interested parties can offer input at the March 13 meeting of the Management Board or by submitting an online comment or an email to the Bay Program. Learn more.
For many people, the summer months are an ideal time to get outdoors and connect with nature. The 64,000 square mile Chesapeake Bay watershed offers a wide range of recreational opportunities, but with the responsibilities of everyday life, some find it hard to set aside time to enjoy them. If getting outdoors is not an option, don’t fret! Here are eight ways to access the Bay from the comfort of your home or office.

1. NOAA’s Chesapeake Bay Interpretive Buoy System (CBIBS) and Chesapeake Smart Buoy Application. The Chesapeake Bay Interpretive Buoy System (CBIBS) is a network of observation buoys managed by the National Oceanic and Atmospheric Administration (NOAA). The buoys mark various locations along the Captain John Smith Chesapeake National Historic Trail, capturing real-time environmental and weather data such as temperature, wind speed and wave height. This information is available online and on the new “Smart Buoy” application for the iPhone and Android. It is also accessible over the phone: calling the toll-free “dial-a-buoy” number turns each buoy into a floating classroom, as a narrator offers up parcels of information about Captain John Smith’s adventures through the Bay.
We recommend: The data snapshot page for the most up to date data on all of the buoys.

2. Chesapeake Conservancy's Osprey Camera. Ospreys are one of the Bay’s most resilient creatures. After bouncing back from a nearly 90 percent population decline between 1950 and 1970, their growing numbers are now watched as an indicator of Chesapeake Bay health. They mate for life and always return to the same location come nesting season. This nesting habit inspired the Chesapeake Conservancy to place a camera in the nest of their “resident” ospreys, named Tom and Audrey, and stream a live feed 24 hours a day, seven days a week, for anyone who is interested in getting a bird’s eye view of nature’s ultimate “reality show.
We recommend: The Osprey Camera Blog for all things Tom and Audrey. It's an informative and highly entertaining read!
3. Chesapeake Bay Program Website: The Chesapeake Bay Program website highlights the work of the Bay Program and its partners. News and feature stories shed light on our restoration efforts, while data tracks years of restoration work. The website also offers resources that are perfect for students and teachers, from a series of pages that offer an in-depth look at the issues restoration partners must face to a collection of photos and maps.
We recommend: Using our Field Guide to learn about the hundreds of critters that call the Bay watershed home!
4. From your phone! Chesapeake Explorer and National Wildlife Refuge Applications: In this age of innovation, technology is constantly evolving and changing the way we view the world. The widespread popularity of smart phones and tablets has inspired the National Park Service (NPS) and a small New York start-up called Network Organisms to create applications that allow people to explore the Bay from the palm of their hand. The National Wildlife Refuges: Chesapeake Bay application for iPhones encourages users to explore the 11 National Wildlife Refuges around the Bay, sharing wildlife sightings and connecting with other outdoor enthusiasts. Chesapeake Explorer is compatible with both iPhone and Android devices. It helps people find places around the watershed based on specific activities, trail names or types of sites. Both applications are free, so get your phone out and start exploring!

5. National Geographic’s Chesapeake Bay Field Scope: National Geographic’s Chesapeake Bay Field Scope is a tool that promotes the exploration, sharing and analysis of the Bay. Users are presented with real-world data sets about rivers and streams, wetlands, elevation, water depth and more. The information on this site is collected from students and scientists that work directly with the Bay. The site also features a map layering tool, a set of student observations and real time data comparisons.
We recommend: Using Query Point to get instant information about any given point on a map.
6. Chesapeake Bay Gateways Network: The Chesapeake Bay Gateways Network was created in 2000 by the National Park Service (NPS) as a resource to connect people to authentic Bay experiences, sights and places. Today, more than 160 parks, wildlife refuges, museums, sailing ships, historic communities, trails and more are part of the Gateways Network. The network allows visitors to search for sites, watch slideshows, make plans to visit and learn about the Bay.
We recommend: Listening to the Sounds of the Bay. These audio excerpts from Window on the Chesapeake: The Bay, Its People, and Places take listeners on a journey through the Bay.
7. Maryland Healthy Beaches: Plan on heading to a Maryland beach this summer? Be sure to check the Maryland Healthy Beaches' Beach Notification System before you go. This application is updated with the most current beach advisories, closures, and bacteria levels. The notification system also provides rainfall accumulation data for every beach location.
We recommend: Visiting the Healthy Beach Habitats page for helpful tips about how to enjoy the beach the healthy way.
8. National Geographic’s Exploring the Chesapeake: Then and Now. Are you a history buff? National Geographic’s Exploring the Chesapeake: Then and Now puts the Bay’s past and its present at a user’s fingertips. National Geographic launched the website alongside the 400th anniversary of the establishment of Jamestown, with the intention that it would be used to compare the world that John Smith lived in to the present day. The site includes lesson plans for educators, links to stories about the Bay, travel guides, field trip suggestions and more.
We recommend: Exploring the Chesapeake Bay as if it were the 1600’s with the site's interactive mapping tool.
Nutrient pollution in the majority of the Chesapeake Bay region’s freshwater streams and rivers has decreased over the last 25 years, according to data from scientists with the U.S. Geological Survey (USGS) and the Chesapeake Bay Program.
Almost 70 percent of the watershed’s 32 monitoring locations show decreasing nitrogen and phosphorus levels, meaning fewer of these harmful nutrients are entering the Chesapeake’s local waterways. Approximately 40 percent of the sites show decreasing trends for sediment pollution.
Although this data may indicate long-term improvements in the health of the Bay’s streams and rivers, pollution loads to the Bay were higher in 2010 due to more rain, snow and river flow.
“These long-term trends indicate that pollution reduction efforts, such as improved controls at wastewater treatment plants and practices to reduce nutrients and sediment on farms and suburban lands, are improving water quality conditions in many areas,” said USGS scientist Scott Phillips. “However, nutrients, sediment and contaminants will need to be further reduced to achieve a healthier Bay and streams.”
Each day, billions of gallons of fresh water flow through thousands of streams and rivers that eventually empty into the Bay. This fresh water is known as “river flow.” In general, as river flow increases, more nutrient and sediment pollution is carried downstream to the Bay. Pollution levels in rivers vary greatly from year to year because they are influenced by rainfall. Scientists make adjustments to remove the effects of weather variations, allowing consistent measurement of pollution levels over time and better evaluation of long-term changes.
In the 2010 water year (October 2009-September 2010):
The Bay Program’s goal is to have a long-term average of 186 million pounds of nitrogen and 12.5 million pounds of phosphorus entering the Bay from streams and rivers.
In a different, shorter-term study conducted between 2000 and 2008, the health of individual freshwater streams across the watershed showed mixed conditions. Of the 7,886 stream sites sampled, more than half (55 percent) were found to be in very poor or poor condition. The remaining 45 percent were found to be in fair, good or excellent condition.
This study uses data on the tiny, bottom-dwelling creatures that live in freshwater streams and rivers as an indicator of overall stream health. This method provides a uniform evaluation of the health of local waterways across state lines and throughout the entire Bay watershed.
The USGS estimates how much river flow enters the Bay each year, monitors pollution loads in the Bay’s major rivers, and works with the Bay Program to estimate how much pollution reaches the Bay. To learn more about the USGS’s Chesapeake monitoring activities, visit http://chesapeake.usgs.gov.
