Nisqually River Project

For more than 80 years, the Nisqually River Project has generated clean, renewable electricity while supporting recreation, fish and wildlife, and environmental stewardship in the Nisqually River watershed.

Located along the Nisqually River in Pierce County, the project includes Alder Dam (1945) and LaGrande Dam (1945), two powerhouses, Alder Lake, recreation areas, and thousands of acres of protected wildlife lands. Tacoma Power works with Tribal partners, state and federal agencies, and local communities to balance reliable renewable energy with stewardship of the river and surrounding lands.
