[2][3] In 1975, the Juneau Lions Club built a trail from the Eaglecrest Ski Area to the lake.

[5][6] On June 7, 2010, the Juneau Assembly was to appropriate a $133,180 grant from the Alaska Department of Natural Resources to fund improvements to a nearby trail from the Eaglecrest lodge to a bridge over Fish Creek.

The soil around the shores of the lake consists mainly of muskeg covering till (glacial sediment) above bedrock.
