The Deschutes Estuary is in the cities of Olympia and Tumwater in Thurston County where the mouth of the Deschutes River enters Budd Inlet. The estuary became Capitol Lake with construction of the Fifth Avenue Dam in 1951. Developing a politically acceptable strategy for restoration of the estuary has been a long term effort. Percival Creek Watershed drains to the west side of the estuary. The historical Estuary could be defined to include several small tributaries in south Budd including Indian-Moxlie Creek Watershed, now buried and entering East Bay in a pipe, as well as Schneider Creek Watershed at West Bay. The Estuary is a MTCA cleanup site, part of the Puget Sound Initiative.
