Mud Creek Dam, located in Malheur, Oregon, is a federal-owned structure primarily designed for water supply purposes. Completed in 1961 by the Bureau of Land Management, this gravity dam stands at a structural height of 7 feet and has a hydraulic height of 6 feet, with a length of 570 feet. The dam has a storage capacity of 295 acre-feet, with a normal storage level of 126 acre-feet, serving a drainage area of 10.2 square miles.

With a low hazard potential and a moderate risk assessment rating, Mud Creek Dam is considered to be in good condition, albeit not rated for its current state. The dam has not been modified in recent years and does not have an emergency action plan prepared. Despite its uncontrolled spillway type, the dam has not had any issues with discharge, with a maximum capacity of 76 cubic feet per second. The last inspection in September 2018 indicated a need for inspections every 5 years to ensure the dam's continued safety and functionality.

In the event of an emergency, there is no designated emergency contact list or inundation maps prepared for the area. However, with the Bureau of Land Management overseeing its construction, regulation, inspection, and operation, Mud Creek Dam remains a vital water resource infrastructure in Oregon, providing essential water supply to the surrounding area.
