Located in Okanogan, Washington, the Owhi dam was completed in 1915 by the Bureau of Indian Affairs with a primary purpose of serving as a Fish and Wildlife Pond. The earth dam has a structural height of 12 feet and a length of 150 feet, creating a storage capacity of 3000 acre-feet along the Little Nespelem River. The dam is owned and funded by the Bureau of Indian Affairs, with responsibilities for design, construction, regulation, inspection, and operations all falling under their jurisdiction.

Despite being categorized with a high hazard potential, the condition assessment of the dam is not available. The last inspection took place in 2012, with a scheduled frequency of inspections every 5 years. The Emergency Action Plan (EAP) status is unclear, and there is no risk management plan in place. The risk assessment indicates a very high risk level, highlighting the need for further evaluation and potential measures to enhance the safety and resilience of the Owhi dam. Enthusiasts of water resources and climate change will find the Owhi dam to be a key feature in the landscape of Washington, warranting attention and proactive management to ensure its continued functionality and safety in the face of potential hazards and changing environmental conditions.
