Tidal Basin

The Tidal Basin is a natural lake found in 2277.

Background
Before the war, it was a good fishing and boating port, with the Jefferson Memorial in its center. When the bombs fell, mirelurks colonized in it, hundreds breeding and infesting the water. The basin is filled with many row boats, tugboats, and Dinghies. Many boxes of loot are still aboard the half-sunken, and deteriorated boats that mar in the shallows of the District's port basin.

It's surrounding territory was being fought over by the Brotherhood of Steel, The Enclave, and the super mutant hordes that occupied Downtown Washington D.C., and in 2277 the Brotherhood won it over and gained control of Project Purity.

Appearances
Tidal Basin appears in Fallout 3.
