The Upper Pahranagat Dam, located in Glendale, NV, is a Federal-owned structure managed by the Fish and Wildlife Service. Constructed in 1937, this Earth-type dam stands at a height of 15 feet and spans a length of 1515 feet along the White River. Its primary purpose is to serve as a Fish and Wildlife Pond, with a normal storage capacity of 2170 acre-feet and a maximum storage of 4688 acre-feet.

Despite its low hazard potential, the dam's condition assessment is rated as poor as of November 2018. It has undergone modifications in 1998 and 2010 to enhance its hydraulic capabilities. The dam's spillway is uncontrolled and has a width of 123 feet, allowing for a maximum discharge of 905 cfs. While the risk assessment deems the dam to have a moderate risk level, there are no Emergency Action Plans in place, raising concerns for potential emergency response scenarios.

Water resource and climate enthusiasts monitoring the Upper Pahranagat Dam should take note of its critical condition assessment and lack of emergency preparedness measures. With its location in Lincoln, Nevada, and under the jurisdiction of the Nevada Department of Water Resources, there is a need for ongoing monitoring and maintenance to ensure the safety and integrity of this vital water infrastructure for the surrounding ecosystem and wildlife habitats.
