Biscuit is a privately owned dam located in Niobrara, Wyoming, with a primary purpose of irrigation. Constructed in 1977 by Lawrence T. Price, the Earth-type dam stands at a height of 24 feet and has a hydraulic height of 17 feet. The dam stretches 506 feet in length and has a storage capacity of 83 acre-feet, with a maximum discharge of 4,423 cubic feet per second.
Despite being regulated and inspected by the State of Wyoming, Biscuit is currently assessed as being in poor condition with a low hazard potential. The dam's spillway type is uncontrolled, with a spillway width of 200 feet and an outlet gate in the form of a slide (sluice gate). With a risk assessment rating of moderate (3), there are no emergency action plans in place, and the last inspection took place in March 2020, highlighting the need for continued monitoring and maintenance to ensure the safety and efficiency of this vital water resource infrastructure.
Situated on the Conley Draw tributary of Indian Creek, Biscuit serves as a critical water management structure in the region, supporting agricultural activities through irrigation. As climate change impacts intensify, the proper functioning and maintenance of dams like Biscuit become even more crucial in ensuring water security and resilience in the face of changing environmental conditions. It is essential for stakeholders to prioritize the upkeep and improvement of such infrastructure to safeguard water resources for current and future generations.
