Upper Cottonwood is a Federal-owned dam located in Thermopolis, Wyoming, along the Cottonwood Drain Draw. Constructed in 1973, this Earth dam stands at a height of 12 feet and has a storage capacity of 194 acre-feet. The primary purpose of Upper Cottonwood is to serve as a Fish and Wildlife Pond, while also providing fire protection and stock watering capabilities.

Managed by the Bureau of Reclamation, Upper Cottonwood has a low hazard potential rating and is state-regulated for permitting, inspection, and enforcement. The dam features an uncontrolled spillway and a slide (sluice gate) outlet gate. Despite its moderate risk assessment rating, the dam's condition assessment is currently unavailable, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity and safety for the surrounding community and environment. For water resource and climate enthusiasts, Upper Cottonwood presents an intriguing case study in dam management and regulation within the state of Wyoming.
