Phillips No. 1 is a privately owned earth dam located in Torrington, Wyoming, along the Phillips Draw river. Built in 1953 for irrigation purposes, this dam stands at 28 feet high with a storage capacity of 122 acre-feet. Despite its low hazard potential, the dam is currently in poor condition, as assessed in August 2019. It has a moderate risk assessment score of 3, indicating the need for risk management measures to mitigate potential issues.

The dam's primary purpose is irrigation, but it also serves for fire protection, stock watering, and small fish pond purposes. With a spillway width of 50 feet and an uncontrolled spillway type, Phillips No. 1 has a slide gate for outlet control. However, the dam lacks drainage area and maximum discharge capacity, which could pose challenges during periods of heavy rainfall or flooding. Despite these limitations, the dam has been inspected every 5 years to ensure its structural integrity and safety.

Located in Albany County, Wyoming, Phillips No. 1 is overseen by the Wyoming State Engineer's Office and falls under state jurisdiction for regulation, permitting, inspection, and enforcement. As climate change continues to impact water resources in the region, maintaining and upgrading infrastructure like Phillips No. 1 will be crucial for sustainable water management and resilience against changing weather patterns.
