Thunderbird Park Reservoir, located in Glendale, Arizona, serves as a crucial water supply source in Maricopa County. Built in 1985, this Earth dam stands at a height of 44 feet and spans 600 feet in length, with a storage capacity of 39.8 acre-feet. The reservoir covers a surface area of 2.4 acres and has a drainage area of 0.01 square miles, providing essential water resources for the region.

Managed by the Arizona Department of Water Resources, Thunderbird Park Reservoir boasts a high hazard potential due to its location along an unnamed wash. Despite this, the condition assessment in 2018 deemed the dam to be satisfactory. With a maximum discharge capacity of 75 cubic feet per second and an uncontrolled spillway type, the reservoir plays a vital role in mitigating flood risks and ensuring water supply reliability. Climate and water resource enthusiasts will find Thunderbird Park Reservoir to be a fascinating example of infrastructure designed to address the challenges of water management in a changing climate.
