South Lodgepole No. 1 is a privately owned water resource structure located in Weston, Wyoming, along HWY. 450. Constructed in 1969 by Delbert E Robinson, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a hydraulic height of 13 feet and a structural height of 18 feet, the dam has a storage capacity of 197 acre-feet and covers a surface area of 19 acres. Despite its low hazard potential, the dam is in poor condition as of its last inspection in September 2017.

Situated on the WELL DRAW tributary of the Lodgepole Creek, South Lodgepole No. 1 plays a crucial role in flood risk reduction for the area. The dam has an uncontrolled spillway with a width of 100 feet and an outlet gate for controlled water release. Although it has not been modified over the years, the dam is subject to regular state inspection, enforcement, and permitting, as it falls under Wyoming's jurisdiction and is regulated by the State Engineer's Office.

With a moderate risk assessment rating of 3, South Lodgepole No. 1 requires attention to improve its condition assessment and ensure the safety and effectiveness of its operations. As climate change continues to impact water resources and infrastructure, enthusiasts and stakeholders in water management and climate resilience should monitor the maintenance and regulatory efforts concerning this vital water resource structure in Wyoming.
