Little Blue Creek is a privately owned water resource located in Owyhee, Idaho, with a significant impact on the surrounding area. Completed in 1914, this earth dam stands at a height of 37.2 feet and serves multiple purposes, including flood control and water storage for irrigation. With a normal storage capacity of 2100 acre-feet and a drainage area of 30 square miles, Little Blue Creek plays a crucial role in managing water resources in the region.

Despite its importance, the condition assessment of Little Blue Creek is rated as poor, with a significant hazard potential and a very high risk assessment. The dam's last inspection in 2015 highlighted the need for improvements to ensure its continued safety and functionality. Located in a remote area, the dam's ownership by a private entity raises questions about its maintenance and regulatory oversight, especially with regards to state permitting, inspection, and enforcement.

As a key feature in the watershed of Little Blue Creek and Blue Creek, this dam requires attention and investment to address its poor condition and mitigate potential risks. With its controlled spillway and limited emergency preparedness measures, the future of Little Blue Creek's impact on water resources and climate resilience in the region hinges on proactive maintenance and regulatory actions to ensure its safety and effectiveness for years to come.
