Twin Lakes Estates is a 55+ mobile home park in Shasta Lake, California. The project site is a small manmade pond (reservoir) bounded on the upstream side by the clubhouse structure, which straddles the creek, and on the downstream side by an earthen dam with a concrete spillway. Beavers are present in the reservoir and have blocked the concrete outlet spillway, raising the pond level by 8-10 inches and causing damage from flooding of nearby buildings and infrastructure. Foraging beavers have also caused damage to trees surrounding the reservoir, increasing risk to human safety and infrastructure from falling trees. The Twin Lakes Estates Beaver Coexistence Project will install one beaver exclusion fence across a manmade spillway with one floating pond leveler installed into this fence to manage water levels (a common flow device strategy called pipe-and-fence). This project will also protect 20 large deciduous trees with fencing to protect them from beaver foraging.
