Genesee's Water Storage Reservoir:
Genesee Water & Sanitation District built a dam and reservoir in 2008 that is on a small gulch tributary to Bear Creek half way between Idledale and Kittredge near mile marker 12 on State Highway 74. It can only be viewed from a small section of eastbound 74.
Dam Statistics: Building a safe and secure dam was the number one concern of the District. Minimizing environmental impacts and preserving the natural beauty of the canyon followed by safety were top priorities as well. The following summarizes key elements of the project:
