 Most of the reclaimed mudflats were subsequently declared to be parkland and named Anacostia Water Park (now Anacostia Park) in 1919.The original dredging plan called for a channel wide on the Anacostia's west bank from the 11th Street Bridges to Massachusetts Avenue SE, narrowing to a wide channel from Massachusetts Avenue SE to the Maryland-District border line.In addition to this channel (which was meant to facilitate the passage of cargo ships) the McMillan Commission proposed building a dam across the Anacostia River at Massachusetts Avenue SE or at Benning Bridge to form a large lake for fishing and recreational boating.
