Simplot Lrar Lagoon, located in Moses Lake, Washington, is a privately owned offstream lagoon that was completed in 2006 by Pharmer Engineering. This earth dam structure has a hydraulic height of 24 feet and a length of 1448 feet, providing a storage capacity of 67 acre-feet for water resource management. The lagoon covers a surface area of 2.7 acres and is regulated by the Washington Dept of Ecology, ensuring compliance with state permitting, inspection, and enforcement requirements.

With a low hazard potential and a condition assessment of "Not Rated," Simplot Lrar Lagoon serves a primary purpose of "Other" and is classified as an earth dam with rockfill core types and soil foundations. The lagoon plays a crucial role in water management for the Crab Creek watershed, contributing to the conservation of water resources in the region. Despite not having a designated spillway type or outlet gates, the lagoon's design and construction meet state regulatory standards for water storage and management.

For water resource and climate enthusiasts, Simplot Lrar Lagoon offers a fascinating case study in private water infrastructure development and management. Its strategic location in the Moses Lake area and affiliation with the Seattle District of the USACE highlight the importance of sustainable water storage solutions in arid regions like Grant County, Washington. As the lagoon continues to support local agriculture and environmental conservation efforts, it stands as a testament to the innovative engineering and regulatory oversight that drive effective water resource management in the Pacific Northwest.
