This was a Digital Photography Meetup at Kerr Dam In Polson MT. Two of us attended. Kerr Dam is a three-unit hydroelectric plant on the Flathead River about five miles southwest of Polson and the natural outlet of Flathead Lake. The units have a total generating capacity of 196 megawatts. (One megawatt can satisfy the average energy needs of 750 households.)

The dam, which began operation in 1938, is 541 feet long and 205 feet high. Its installation raised the level of Flathead Lake by 10 feet over the natural lake outlet. The dam’s 28-mile-long reservoir has a storage capacity of 1.2 million acre-feet. Kerr Dam is classified as a “storage generation” project because it uses the water stored in its reservoir to generate electricity.
