Pyramid Dam, located in TENSLEEP WY, Wyoming, is a gravity dam constructed in 2003 with a primary purpose listed as "Other." The dam, managed by the Bureau of Land Management, stands at a structural height of 30 feet and has a hydraulic height of 25 feet. It has a storage capacity of 59.21 acre-feet, with a normal storage level of 29.64 acre-feet.
Despite being classified as having a low hazard potential, Pyramid Dam is currently in poor condition, as reported in the last inspection in August 2016. The dam lacks an emergency action plan and has not been assessed for its condition in recent years. With a high risk assessment rating of 2, there is a need for improved risk management measures and updated emergency preparedness protocols for the dam.
Overall, Pyramid Dam serves as a critical water resource in Washakie, Wyoming, regulating the flow of the PYRAMID DRAW river. As a federal structure under the jurisdiction of the Bureau of Land Management, there is a call for increased attention to its maintenance and safety measures to ensure the continued protection of the surrounding communities and environment in the face of potential climate challenges.
