SITE OVERVIEW:
1003 is located near the spillway for Maple Grove Reservoir along Lena Gulch. Downstream locations are protected by Maple Grove Reservoir up to a 100-year event. Once an event reaches 500-year runoff the reservoir must begin releasing a large volume of water to protect the structure. Downstream floodplain areas will be at risk in large events.
