A second dam, built of concrete in 1926 and opened in 1927, replaced the first dam, which was not removed and lies submerged in the reservoir. Almost unchanged since 1926, the dam is 782 ft long and 34.5 ft high, and its powerhouse contains three turbines capable of generating seven megawatts (MW) of power each. The maximum power output of the dam is 18 MW. Montana Power Company built the second dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014. The reservoir behind the dam has no official name, but was called the Long Pool for many years. The reservoir is about 2 mi long, and has a storage capacity of 1,710 acre.ft to 1,820 acre.ft of water.

Spokane House Spokane House was a fur trading post founded in 1810 by the British-Canadian North West Company, located on a peninsula where the Spokane River and Little Spokane River meet. When established, it was the North West Company's farthest outpost in the Columbia River region. An American rival of the NWC, the Pacific Fur Company opened a station adjacent to Spokane House, called Fort Spokane. The War of 1812 and ongoing supply issues caused the collapse of the PFC, with its posts now under the control of the NWC. The original Spokane House was abandoned in favor of Fort Spokane, though the latter location was still called Spokane House. The second Spokane House saw use as a major post in the interior Oregon Country until the NWC was absorbed by the Hudson's Bay Company in 1821. During a general tour of the Pacific Northwest, Spokane House was abandoned by George Simpson in 1825, in favor of a new post that became Fort Colvile. The site of Spokane House is in Spokane County in the U.S. state of Washington, just northwest of the city of Spokane.
