Dominant Land Uses
Summary of the largest Anacostia land use/land cover categories by area in the subwatershed; general categories include residential, commercial, industrial, institutional, agricultural, parks, forest, wetlands, extractive federal, and water.

Physical Characteristics
Subwatershed features such as size, physiographic province(s), percent impervious, elevation range, and stream gradient.

Biological Characteristics
The quality of the fish and macroinvertebrate community and the condition of the aquatic habitat. In the Maryland portion of the watershed, aquatic biota and habitat condition are presented as scores relative to (as a percentage of) local high quality reference streams (Cummins et al., 1991). For the District portion of the watershed, a reference stream was not found; instead, observed conditions were compared to ranges of known or expected values associated with different levels of ecological impairment (Johnson, 1989).

Condition Summary
Discussion of the degree, type, and distribution of development in the subwatershed as it relates to aquatic habitat/biota and water quality; the remaining total and riparian forest cover are also included.

Finally, demographic information has been summarized for the Anacostia watershed, as well as for each of the individual subwatersheds..
