About Lake Sugema Silt Control Dam
The primary purpose of Lake Sugema Silt Control Dam is debris control. The dam is designed to catch sediment, rocks, and debris carried by flowing water — particularly important in areas prone to mudslides or heavy erosion. The dam is owned by Iowa Department of Natural Resources (state). It impounds the Tr-indian Creek near Lake Sugema.
