Standley Lake Regional Park & Wildlife Refuge is a major municipal reservoir and bird sanctuary located in Westminster, Colorado. It serves as a primary drinking water source for several surrounding communities, resulting in strict water-quality regulations. The park encompasses over 1,200 acres of water surface area and extensive surrounding trails. It acts as a critical nesting site for bald eagles, which leads to periodic seasonal closures of specific shoreline areas. The refuge is a designated stop for various migratory waterfowl species. Recreational activities include fishing, kayaking, canoeing, and stand-up paddleboarding, all of which require specific seasonal permits.
