Mountain Pond Dam, also known as Broetje Mountain Pond Dam, is a privately owned structure in Walla Walla, Washington, designed for irrigation purposes. Completed in 1992, this earth dam stands at a hydraulic height of 40 feet and a structural height of 42 feet, with a storage capacity of 26 acre-feet. Situated on the Snake River offstream, the dam serves the crucial function of providing water for irrigation in the region.

Managed by the Washington Department of Ecology, the dam is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with environmental standards. With a hazard potential rated as high and a fair condition assessment, the dam is regularly inspected every five years to monitor its structural integrity. Despite its relatively small surface area and drainage area, Mountain Pond Dam plays a significant role in supporting agricultural activities in the area, highlighting the importance of water resource management in a changing climate.

As climate change poses threats to water availability and quality, the maintenance and regulation of dams like Mountain Pond Dam become increasingly important in sustaining water resources for irrigation and other purposes. With its critical role in supporting agriculture in the region, ensuring the safety and efficiency of Mountain Pond Dam is essential for both water resource and climate enthusiasts who recognize the significance of water management in a changing environment.
