Hickey Run is a small, largely free-flowing tributary of the Anacostia River. The stream joins the river immediately upstream of the Langston Golf Course in Washington, DC. The subwatershed is generally bound by Rhode Island Avenue to the north, 13th Street to the west, South Dakota Avenue and the Anacostia River to the east, and M Street and the Langston Golf Course to the south. The entire subwatershed is located within the District of Columbia. Springhouse Run is the largest, of the four open tributaries remaining in the Hickey Run subwatershed. The lower main stem downstream of Crabtree Road is tidally influenced.
Dominant Land Uses: Dominant land uses in the subwatershed include parkland (34%), industrial (30%), and residential (29%).
Physical Characteristics: The Hickey Run subwatershed is approximately 1,102 acres (1.7 mi2) in size and approximately 41 percent impervious. It is the most impervious Anacostia subwatershed within the District of Columbia. Hickey Run is located entirely within the Coastal Plain physiographic province. Geologically, the Coastal Plain portion of the Anacostia watershed is characterized by largely unconsolidated sedimentary deposits of sands, gravels, silts and clays.
Biological Characteristics: Hickey Run is designated as a Class 'A', 'B', 'C', and 'D' stream (i.e., Class 'A'= Primary Contact Recreation; 'B'= Secondary Contact Recreation and Aesthetic Enjoyment; 'C'= Protection and Propagation of Fish, Shellfish and Wildlife; and 'D'= Protection of Human Health Related to Consumption of Fish and Shellfish) by the District Department of the Environment (DDOE). Hickey Run Index of Biotic Integrity (IBI) main stem and tributary sampling stations were rated as having either partially or non-supporting physical aquatic habitat conditions present. The condition of macroinvertebrate populations in both the Hickey Run main stem and its tributary network is very poor. The Hickey Run main stem downstream of New York Avenue supports a small pollution tolerant fish community. Unfortunately, for decades the stream has been the recipient of major inputs of oil and grease from industrial sites located upstream of New York Avenue. It should be noted that the stream has the dubious distinction of having actually caught on fire in the 1930's. In general, both main stem and tributary aquatic communities remain severely impacted.
Several physical barriers to both resident and anadromous fish movement and migration are present (e.g., weirs, piped stream sections, etc). These, as well as other barriers in Hickey Run have been identified and remain as a restoration challenge for this subwatershed. It should be noted that efforts on the part of DDOE and others to control stormwater runoff, reduce hydrocarbon pollution and trash loadings, restore both tributary and main stem instream habitat, create wetlands, reforest riparian corridors, and reintroduce native fish species to the subwatershed remain on-going.
Condition Summary: Hickey Run is the most altered major stream within the District of Columbia's portion of the Anacostia. Approximately 85 percent of the total subwatershed area is developed, stormwater management controls are few, imperviousness levels are high (i.e., 41 percent) and roughly 36 percent of the stream miles have an adequate riparian forest buffer (i.e., 300-foot total width). Not surprisingly, far more stormwater retrofitting and stream restoration efforts are needed to restore the aquatic ecosystem of the Hickey Run subwatershed. Planned future projects include, but are not limited to: stormwater management focusing on the employment of low impact development (LID) and environmentally sensitive design (ESD), wetland creation, aquatic and terrestrial habitat restoration, fish barrier modification/removal, invasive plant management, trash reduction and potentially additional fish reintroductions.
