The Friesland Dairy Lagoons in Yakima, Washington, are privately owned and regulated by the Washington Department of Ecology. These lagoons, completed in 2013, have a hydraulic height of 5.5 feet and a storage capacity of 10 acre-feet. The primary purpose of these earth dams is for other uses, and they serve as an essential water resource management system in the region.

Despite being privately owned, the Friesland Dairy Lagoons are subject to state regulations, inspections, and enforcement to ensure their safety and environmental compliance. The dams have a high hazard potential, but their condition is assessed as fair. The last inspection in 2018 deemed them to be in satisfactory condition, with a regular inspection frequency of every five years.

Located in Congressional District 04, Washington, the Friesland Dairy Lagoons play a crucial role in water management and climate resilience efforts in the region. With their strategic design and state oversight, these lagoons serve as a model for effective water resource management and environmental protection in the dairy industry.
