Long Lake Dam
Lake Spokane, a 24 mile long reservoir, is so named because of its close proximity to Spokane, Washington. However, some people call it Long Lake, after its dam, Long Lake Dam. The dam was built in a spot where the Spokane River makes a complete horseshoe bend and was completed in 1915. At that time Long Lake Dam had the distinction of being the tallest dam in the world.
Nine Mile Falls Dam
Today, Long Lake Dam is listed in the National Register of Historic Places due to it’s previous architectural reign. Nine Mile Falls Dam is located at the headwaters of Lake Spokane.
