Lewiston Lake Professional Review and Guide
"Lewiston Lake is unusual for a reservoir because its level doesn’t fluctuate. Its purpose is to provide a constant flow of water through the Clear Creek Tunnel, which delivers water to a power house at Whiskeytown Reservoir. As a result, it looks very much like a natural lake with some marshy shores.
