Dry Wash No. 2 is a significant irrigation structure located in San Juan, Utah, along Johnson Creek. Constructed in 1962 by the USDA NRCS, this earth dam stands at a hydraulic height of 63 feet and a structural height of 68 feet, with a storage capacity of 660 acre-feet. The dam serves the primary purpose of irrigation and is regulated by the Utah Division of Water Rights, ensuring that it meets state standards for inspection, enforcement, and permitting.

Managed by a private owner, Dry Wash No. 2 plays a crucial role in water resource management in the region, with a drainage area of 0.14 square miles and a maximum discharge of 72 cubic feet per second. The dam's spillway width of 40 feet and inspection frequency of every two years highlight its importance in maintaining water quality and safety for downstream communities. Despite its significant hazard potential, with a condition assessment currently listed as "Not Rated," efforts are being made to ensure the structure's integrity through regular inspections and potential emergency action planning.

As a key component of the local water infrastructure, Dry Wash No. 2 represents the intersection of climate resilience and resource management in the arid landscape of Utah. With its earth core and stone foundation, this dam stands as a testament to the collaborative efforts of federal and state agencies in safeguarding water resources for agricultural purposes. Its location in Blanding, Utah, under the jurisdiction of the Sacramento District, showcases the importance of strategic water storage and distribution in mitigating the impacts of a changing climate on regional water availability.
