“Tacoma Power began generating electricity on the Nisqually River over 90 years ago. The original LaGrande Dam, completed in 1912, was replaced in 1945 with Alder Dam and the new LaGrande Dam. The Nisqually River Project is now Tacoma Power’s second-largest hydroelectric resource, generating nearly 600 million kilowatt-hours of electricity each year, enough to serve nearly 43,000 Northwest homes.

Alder Dam forms the 3,000-acre Alder Lake. The Alder Lake Recreation Area is ideal for boating, fishing, swimming and camping. Tacoma Power provides several top-quality recreational facilities at Alder Lake…

A popular community service at the Nisqually Hydroelectric Project is free group tours. Tours are available for school, civic, business and recreational groups during regular working hours by appointment. To make arrangements for a tour, call Tacoma Power at 253-502-8759.”
