The earth dam, standing at 12 feet high with a storage capacity of 170 acre-feet, was completed in 1920 along the TR-Rattlesnake Creek. With a low hazard potential and no current condition rating, the dam plays a crucial role in supporting agricultural activities in the region.
Despite being under state jurisdiction and regulation by the Department of Natural Resources and Conservation (DNRC), Peterson Lake has not been rated for its condition assessment. While it has not been inspected recently and lacks an Emergency Action Plan (EAP), the dam remains a vital infrastructure for water storage and distribution in the area. The risk management measures and preparedness for potential emergencies are areas that could be improved for the long-term sustainability of the dam.
With its location in the beautiful city of Missoula and its importance for irrigation, Peterson Lake serves as a significant water resource for the community. As climate change continues to impact water availability and usage patterns, ensuring the safety and efficiency of dams like Peterson Lake will be crucial for adapting to the changing environmental conditions and maintaining a reliable water supply for agricultural activities in the region.
