Buck Butte Reservoir, located in Klamath, Oregon, is a privately owned Earth dam structure primarily used for irrigation purposes. Constructed in 1976 by the Natural Resources Conservation Service, this reservoir stands at a height of 25 feet with a storage capacity of 114 acre-feet. The reservoir covers a surface area of 19.5 acres and is fed by Simons Creek, with a drainage area of 4.01 square miles.

Despite its low hazard potential, Buck Butte Reservoir is regulated and inspected by the Oregon Water Resources Department, ensuring its structural integrity and compliance with state regulations. The reservoir has not been rated for its condition assessment, and its last inspection was conducted in August 2017. With a normal storage capacity of 114 acre-feet and a maximum discharge of 188 cubic feet per second, Buck Butte Reservoir plays a crucial role in sustaining irrigation activities in the region.

While the reservoir does not have a spillway or outlet gates, its relatively small size and low-risk profile make it a vital water resource for the surrounding agricultural lands. As water resource and climate enthusiasts, the unique features and purpose of Buck Butte Reservoir provide an interesting case study in sustainable water management and the importance of maintaining infrastructure for irrigation in a changing climate.
