I was wondering how a lake would be heated, so I did some google searching and found that Belews Lake is heated by Belews Creek Power Station, a coal-burning power plant. They have a 38% efficiency rating. The remaining 62% is released in the form of heat, and dumped into the lake. In fact, the lake was formed for the purpose of providing cooling water for the power station.
I'm sure this is great during the winter, but I'm wondering how warm it gets in the summer!
