DC officials warn that Hurricane Isaias affected a number of rivers and creeks in the DMV area, causing their bacteria levels to rise.
A total of 12 areas in the District, including several in the Potomac River (the Washington Canoe Club, Fletcher’s Cove and Columbia Island) and the Anacostia River (near the National Arboretum, Hickey Run, Yards Park, Anacostia Park and Buzzard Point), have high levels of bacteria, according to tests conducted by Anacostia Riverkeeper in the region.
Seven spots in some waterways in Rock Creek Park such as the areas of Pinehurst Branch, Broad Branch and P Street Beach are also on the list.
Four spots in Maryland in the Upper Anacostia Watershed also turned out to have higher than normal bacteria levels.
Here is further details about the water quality in the District.
