Ponch is a privately owned earth dam located in Campbell, Wyoming, near Powderville Montana. Built in 1968 by designer Walter J Pilch, Ponch serves multiple purposes including fire protection, stock watering, and a small fish pond. The dam stands at 19 feet high with a hydraulic height of 14 feet, holding a maximum storage capacity of 235 acre-feet and a normal storage of 114 acre-feet. Despite its low hazard potential, Ponch is in poor condition as of the last inspection in August 2017.

Situated on White Tail Creek, Ponch has a spillway width of 50 feet and is equipped with a single slide (sluice gate) outlet gate. The dam's primary source agency is in Wyoming, and it falls under the jurisdiction of the State Regulatory Agency (SEO) with permitting, inspection, and enforcement in place. The risk assessment for Ponch is considered moderate, highlighting the need for ongoing management measures to ensure the safety and integrity of the structure. With its unique location and multiple uses, Ponch remains a significant feature in the water resource and climate landscape of the region.

Ponch's presence on White Tail Creek not only provides essential water resources for fire protection and livestock but also contributes to the local ecosystem as a small fish pond. As climate change continues to impact water availability and quality, the maintenance and management of structures like Ponch become increasingly crucial. With a focus on risk assessment and mitigation, stakeholders can work towards ensuring the long-term sustainability and resilience of Ponch as a valuable water resource in Campbell, Wyoming.
