Avista's Post Falls Hydroelectric Development (HED) has been generating low-cost renewable energy since 1906. To ensure the legacy of this valuable resource, we are restoring the dam on the south channel on the Spokane River in Post Falls, Idaho, beginning in spring 2014 with construction expected to be completed in December 2014.
Here is what will be happening during the project:
- The original 1906 facing concrete and gate frames, along with the manual rack and pinion hoists will be removed. New facing concrete, spillway gates and hoists will be installed.
- New electrical and controls will be added to automate the opening and closing of the spillway gates, increasing efficiencies and reducing costs.
- Other structural and operating upgrades are also included in the project.
- Construction begins in spring 2014 and is expected to be completed in December 2014.
Access to some areas of Q'emiln Park, including the boat launch, trailhead and pavilion, as well as the Spokane River will be impacted during construction to maintain the safety of the public, recreationalists and workers. 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 better understood after a contractor is selected, which is expected to be in January 2014.

Post Falls HED
The Post Falls HED is a series of three structures on the Spokane River, nine miles downstream of Lake Coeur d'Alene in Post Falls, Idaho.
The Middle Channel Dam houses six generating units producing 15 megawatts of clean, renewable energy. That's enough to power 11,250 homes.
The North and South Channel Dams help control water levels of Lake Coeur d'Alene and part of the Coeur d'Alene, St. Joe and St. Maries rivers during the summer recreation season.
