The James River Association has measured an improvement in the overall health of the James River, giving the waterway a “B-” in its latest State of the James report.
Grades are based on four indicators of river health: fish and wildlife populations, habitat, pollution reduction and restoration and protection actions. The river’s score of 61 percent is a four percent increase since the report was last issued in 2013, and it marks the first time the historically-polluted waterway has scored in the “B” range. But according to the report, much work remains to be done, particularly related to sediment pollution in the waterway.
While sediment is a natural part of the environment, excess particles of sand, silt and clay can cloud the water, harming underwater grasses, fish and shellfish. According to the James River Association, sediment pollution in the James has shown little improvement over the past several years, and it continues to pose a significant threat to the long-term health of the river.
According to the report, however, Virginia has made significant strides in reducing nutrient pollution—in particular, pollution from wastewater—as the state works to meet limits set by the Chesapeake Bay Total Maximum Daily Load (TMDL).
Today, the Chesapeake Bay Program unveiled a new, interactive story map—titled “Cleaner Air, Cleaner Bay”—showing how Clean Air Act regulations, as well as decades of enforcement actions, have led to a steady decline in air pollution across the Chesapeake region.
Polluted air can have quite an impact on the health of local waters: scientists estimate that one third of the nitrogen in the Bay comes from the air through a process known as atmospheric deposition. When our cars, power plants or other sources emit air pollution, it can be carried by wind and weather over long distances until it falls onto land or directly into the water.
Even pollution emitted thousands of miles away can eventually end up in our waterways. While the area of land that drains into the Bay spans six states and 64,000 square miles, the Bay’s “airshed”—the area of land over which airborne pollutants travel to enter the estuary—is nine times that size. Nearly three-quarters of the airborne nitrogen that eventually ends up in the Bay is generated by sources within this airshed, and the remaining 25 percent is emitted from sources even farther away. Which is why policies like the Clean Air Act have been essential in reducing the amount of pollution that reaches the Bay.
“We don’t often think about air as a source of pollution to Chesapeake Bay waters,” said Bay Program Director Nick DiPasquale. “The good news, as illustrated by this story map, is that we have been very successful in reducing airborne emissions through Clean Air Act regulations that have improved water quality in the Bay region.”
Excess nitrogen can fuel the growth of harmful algae blooms that block sunlight from reaching underwater grasses and create low-oxygen “dead zones” that suffocate marine life. In addition to national and local regulatory actions, pollution-reducing practices in backyards, in cities and on farms play a critical role in decreasing the flow of nitrogen.

Last month, the final load of juvenile oysters was cast into Harris Creek’s 350-acre oyster reef, marking over two billion oysters planted in the sanctuary. One of the largest oyster restoration projects in the world, the reef in Harris Creek—a tributary of Maryland's Choptank River—is the first of ten Chesapeake Bay tributaries needed to fulfill the oyster restoration goals of the Chesapeake Bay Watershed Agreement.
The juvenile oysters, known as spat, all came from the University of Maryland's Horn Point Hatchery. Oyster restoration in Harris Creek has been a collaborative effort between the National Oceanic and Atmospheric Administration (NOAA), the Army Corps of Engineers, Maryland Department of Natural Resources, the Oyster Recovery Partnership, the Nature Conservancy and other groups, such as the National Fish and Wildlife Foundation. Scientists will continue to monitor the health of the Harris Creek oysters as they look toward restoring more tributaries of the Chesapeake.
We first documented Harris Creek in 2012, when roughly a quarter of the construction and seeding at Harris Creek was complete.

From restoring forests, wetlands and streambanks to reducing pollution from urban, suburban and agricultural lands, 44 environmental projects across the Chesapeake Bay watershed have received $11.5 million in funding from the National Fish and Wildlife Foundation’s (NFWF) Chesapeake Bay Stewardship Fund.
Twenty-four projects will be funded by the Small Watershed Grants Program, which supports on-the-ground restoration, conservation and community engagement. Twenty more will be funded by the Innovative Nutrient and Sediment Reduction Grants Program, which finances the reduction of nutrient and sediment pollution in rivers, streams and the Bay. The 44 projects will leverage more than $22.2 million in matching funds to improve the health of the watershed.
In Maryland, for instance, the Parks & People Foundation will work to improve water quality and public access along Baltimore City’s Gywnns Falls. In Pennsylvania, the Lancaster Farmland Trust will implement 20 agricultural “best management practices” on four farms bordering Mill Creek. And in West Virginia, the Eastern Panhandle Planning and Development Council will transform a previous commercial site into a nursery that grows native plants for use in local green infrastructure projects.
Officials and guests announced the awards this morning at the Prince of Peace Baptist Church in Baltimore, Maryland, where a 2014 Stewardship Fund grant is supporting improvements in managing stormwater runoff.
