Surface Waters

The City of Tumwater is fortunate to have an abundance of fresh water within its jurisdiction. Most of Tumwater's surface waters fall within the Deschutes Watershed. From the Deschutes River and Percival Creek to Barnes and Trosper Lakes, Tumwater's surface waters provide local beauty, habitat for wildlife, and recreation opportunities for community members. 

The Deschutes River, the largest river in the Deschutes Watershed, ends its journey by flowing through Tumwater. The Deschutes flows through Pioneer Park at Henderson Blvd., through the Tumwater Valley Municipal Golf Course, over Tumwater Falls and glides by Tumwater Historical Park. It them empties into the Capitol Lake basin at the base of Budd Inlet.

The Deschutes River provides habitat for many fish and animal species, including the Chinook salmon run managed by the Washington Department of Fish and Wildlife. The numerous parks along the river provide ideal walking and picnic sites. A favorite summertime activity for Tumwater residents is rafting down the Deschutes River from Pioneer Park.
