Delamar Wmp-1, also known as Kinross-Delamar H2o Treatment Pond #1, is a private water management structure located in Idaho's Owyhee County. This water treatment pond plays a crucial role in tailings management, primarily serving as a containment structure for waste materials. Completed in 2009, this earth dam with a stone core stands at a height of 41.5 feet and has a storage capacity of 376 acre-feet.

Managed by the Idaho Department of Water Resources, Delamar Wmp-1 is subject to state regulations, inspections, and enforcement to ensure its safe operation. Despite being classified as having a low hazard potential, the structure received a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and management. The dam's condition was last assessed as satisfactory in April 2016, with regular inspections scheduled every five years to ensure its continued safety and reliability.

Located in a remote area and situated near the Henrietta Drainage and Jordan Creek, Delamar Wmp-1 serves as a critical component of water resource management in the region. With its uncontrolled spillway and valve outlet gates, this structure plays a vital role in safeguarding the surrounding environment and communities from potential water-related risks. As water resource and climate enthusiasts, understanding and monitoring the operation of structures like Delamar Wmp-1 is essential for ensuring the sustainable management of water resources in the face of changing environmental conditions.
