The dam, situated on a tributary of the Cheyenne River, has a maximum storage capacity of 270 acre-feet and a normal storage capacity of 150 acre-feet. With a low hazard potential, the dam is not currently rated for its condition.
Despite being privately owned, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state jurisdiction, permitting, inspection, and enforcement. The dam is not associated with any federal agencies or funding sources. While it does not have a designated primary purpose or specified purposes, Hay Canyon Dam serves as a crucial infrastructure for managing water resources in the region, particularly during times of increased discharge.
Hay Canyon Dam, overlooked by U.S. Representative Dusty Johnson, plays a vital role in water resource management in South Dakota. Its strategic location and design ensure the effective control of water flow and storage, contributing to the overall conservation efforts in the area. As climate change continues to impact water resources, the maintenance and monitoring of dams like Hay Canyon will be essential in ensuring the sustainability and resilience of water systems in the region.
