South Channel Dam at Avista’s Post Falls HED to be Restored   

Tags: Avista Utilities, Hydro power, Spokane River

When you think about historic structures in our region that have undergone important restoration, buildings like The Davenport Hotel, Fox Theater or the Steam Plant might come to mind.
Next year, one of Avista’s historic facilities will be given a much-needed facelift as well.
Built in 1906, the South Channel Dam at the Post Falls Hydroelectric Development (HED) is more than 100 years old. While it’s stood the test of time, we plan to continue the safe and reliable operation of the facility with an extensive restoration and upgrade beginning in spring 2014. Work is scheduled to be completed by December 2014.
The structure’s original facing concrete and gate frames, as well as the gates and manual rack and pinion hoists will be removed and replaced with new facing concrete, automated spillway gates and hoists.  The improvements will preserve the life of the 106-year-old structure and automation will improve operation efficiencies.
During construction the project will affect some areas of Q’emiln Park. To maintain public safety, access to areas including the boat launch, trailhead and pavilion will be impacted. The west entrance road and adjacent portion of the park will be an active construction site with material, equipment and vehicles in the area. More information on the impact will be known after a contractor is selected in January 2014.
It’s easy to stay up-to-date on project information and impacts. Just send us an email at and you will be added to the distribution list for our e-newsletter. Be sure to type "Post Falls Updates" in the subject line and include your name and email address in the body text. You can also get timely project information, including the project fact sheet on our Website.
The Post Falls HED has been a key to helping Avista produce clean, renewable, low-cost power and it creates recreational opportunities like boating and swimming near Q’emiln Park.
Made up of three dams in the area, the Post Falls HED produces 15 megawatts of clean energy – that’s enough to power 11,250 homes – and helps control water levels of Lake Coeur d’Alene during the summer recreation season.
