Microplastics from the Corsica River are pictured at the laboratory of Dr. Lance Yonkos in the Department of Environmental Science & Technology at the University of Maryland in College Park, Md., on Feb. 6, 2015. Microplastics were collected by the National Oceanic and Atmospheric Association Marine Debris Program in 2011 via a manta trawl in four tributaries feeding into the Chesapeake Bay. A study led by Yonkos reports that the prevalence of microplastics in the watershed is positively correlated with population density and proportion of development.

A buffered stream on Brubaker Farm. Brubaker Farms in Lancaster County, Pa., is a 900-cow dairy farm that uses a variety of sustainable features and best management practices for reducing nutrient runoff, such as buffered streams, a methane digester, and no-till crops. It earned owner Luke Brubaker the distinction of being named 2011 Innovative Dairy Farmer of the Year. (Photo by Steve Droter/Chesapeake Bay Program). (Download on Flickr)
Dustin Wichterman, Potomac Headwaters Project Coordinator with Trout Unlimited, holds a brook trout he caught in a tributary of Seneca Creek in Pendleton County, W.Va., on May 2, 2014. Brook trout are the region's only native trout species, and can only survive in cold temperatures and clean water. (Photo by Steve Droter/Chesapeake Bay Program). (Download on Flickr)

Baltimore's Inner Harbor is seen at the far left at the end of the northwest branch of the Patapsco River, which receives water from the mouth of Jones Falls, on June 27, 2016. The Inner Harbor and tidal Patapsco River have received failing water quality grades for years according to a report card published by the Healthy Harbor Initiative for the Waterfront Partnership of Baltimore. Fecal bacteria reaches the water through the city's outdated and leaky sewage system, and pollutants enter with stormwater runoff.

Alewife swim against the current where thousands of herring gather to spawn in a tributary of the Chesapeake Bay in Cecil County, Md., on April 20, 2017. River herring like the alewife and the American shad are anadromous fish that live off the Atlantic coast as adults but journey into freshwater to spawn every spring. Often that journey ends at dams that have cut off thousands of miles of stream habitat. “Last month they were out in the Atlantic ocean somewhere,” said Jim Thompson, a fisheries biologist with the state of Maryland. “That’s why it’s really important to build these (fish) ladders or take these dams out to get them over that last little speed bump so they can spawn.” (Photo by Will Parson/Chesapeake Bay Program).

The Bird River flows into the Gunpowder River in Baltimore County, Md., on June 27, 2016. The 26-square-mile Bird River watershed is about one-third forested land and one-fifth agricultural land. It received Baltimore County's first comprehensive watershed plan in 1995 to address water quality issues caused by unstable stream channels, impervious surfaces, pollutants, mining, agriculture and other threats. Today, completed stream restoration along the mainstem and tributaries of Bird River total five miles. (Photo by Will Parson/Chesapeake Bay Program with aerial support by LightHawk).
