We did no collecting on June 1, but here are some species lists for the record, cited from: Banta, WC (1993) Biological water quality of the surface tributary streams of the District of Columbia. Occ. Publ. Biol. Amer.

We have another 1991 gray literature publication which includes the Anacostia tributaries. It is available as ASCII text . Banta WC and Backus BT 1991. Bryozoans as indicators of water quality in the DC area. Final Report to the US Department of the Interior, DC Water Resources Center. American University, Washington DC. We are working to get the whole text of the DC area report (all 31 DC tributary streams) onto the web.
