Probably, one of the most unusual proposals to use the waters of Eagle Lake was for mining operations at Hayden Hill, located some twenty-five miles north of the lake. It just goes to show, there are a lot of creative individuals out there, past and present.
During the 1920s and 1930s, both the mining activity and the population at Hayden Hill declined. In 1934, Stratton & Stratton of Spokane, Washington consolidated the mine ownership. They had high hopes to revive the Hill. One of the main drawbacks that Hayden Hill suffered was the lack of water for milling. In 1938, Stratton & Stratton proposed to pipe water from Eagle Lake, at a rate of 2,500 gallons per minute. This scheme never came to fruition. There was no Hayden Hill revival.
