Blatt Lake, located in Sublette, Wyoming, is a private fish and wildlife pond that serves as a vital resource for the local ecosystem. Built in 2001, this Earth dam is designed to hold a maximum storage capacity of 600 acre-feet of water and covers a surface area of 35.6 acres. Despite its low hazard potential, the dam's condition assessment indicates it is currently in poor condition, warranting further inspection and potential maintenance in the future.

The dam's primary purpose is to provide a habitat for fish and wildlife, with a normal storage capacity of 149 acre-feet. The lake is fed by Willow Creek offstream and boasts a spillway width of 30 feet. While the risk assessment is categorized as moderate, with a risk level of 3, the dam is not under the jurisdiction of the US Army Corps of Engineers. Notably, the dam is situated on an unnamed ranch in an idyllic rural setting, making it a picturesque location for water resource and climate enthusiasts to explore and appreciate.
