Porter is a private irrigation dam located in Teton, Wyoming, along Wallace Creek. Built in 1951, this earth dam stands at 17 feet high and stretches 245 feet in length, with a storage capacity of 52 acre-feet. Despite its low hazard potential, the dam is rated as being in poor condition, with a moderate risk assessment indicating the need for attention and potential improvements.

Owned privately, Porter is regulated and permitted by the Wyoming State Engineer's Office, with regular inspections conducted to ensure its structural integrity and compliance with safety standards. The dam serves multiple purposes, including irrigation, fire protection, stock watering, and small fish pond management. Its spillway, with a width of 15 feet, is uncontrolled, and the dam features a single valve outlet gate for water release when necessary.

Situated in the Congressional District 00 of Wyoming, Porter is overseen by Liz Cheney (R) and falls under the jurisdiction of the state regulatory agencies. With its location in a scenic area near Moose, this dam on Wallace Creek plays a vital role in supporting water resource management and agricultural activities in the region, highlighting the importance of maintaining and upgrading infrastructure to meet evolving climate challenges and water conservation needs.
