There are five hydroelectric dams on the Pend Oreille River: Waneta (owned by Teck Cominco) and Seven Mile (B.C. Hydro) dams in Canada, Boundary (Seattle City Light), Box Canyon, (Pend Oreille County PUD), and Albeni Falls (U.S. Army Corps of Engineers) dams in the United States. The combined generating capacity of all the dams is approximately 2480 megawatts (MW). Boundary Dam has the largest generating capacity of the five, at 1070 MW. The smaller Albeni Falls Dam regulates the level of Lake Pend Oreille to provide some flood control during the summer and increased flows during dry winters. None of the dams provide for fish passage or navigation.
