Post Falls Dam is a dam on the Spokane River in the city of Post Falls, Idaho. The current dam was constructed in 1906 on the site of an older wooden dam that was used to power a sawmill. Post Falls Dam is commonly referred to in the singular, but the facility actually contains three dams spanning three channels of the Spokane River as it navigates around the Avista Islands.[3] It is the most-upstream dam on the Spokane River, just nine miles from its source at Coeur d'Alene Lake, and the first of seven total dams on the Spokane River.[4]
