Date created: February 17, 2010Tidal waters that are impaired for part or all of the indicated Bay segment by toxic chemicals based on each state's implementation of the Clean Water Act.
View mapFish Passage Progress (2009) in the Chesapeake Bay Watershed
Date created: February 12, 2010Fish passage is a key component to the restoration of anadromous fish (shad and river herring) in the Chesapeake Bay watershed. These fish are blocked from much of their historic spawning areas, which included waters over 200 miles from the Bay. Maryland, Virginia, Pennsylvania and the District of Columbia have set goals to provide fish passage to make much of those historic spawning areas once again accessible to migratory fish. Other species that benefit from the unblocking of streams include eels, native species such as brook trout and other resident species.
View mapBay Grasses (SAV) Restoration Goal Achievement: Single Best Year 2006-2008
Date created: March 24, 2009This map shows progress toward achieving the Chesapeake Bay Program segment-specific underwater bay grass restoration goals. It is based on the single best year of acreage as observed through the most recent three years of data from the Chesapeake Bay underwater bay grasses aerial survey.
