Hulet No 2 Dike, also known as Sinker Creek Dike, is a privately owned structure located in Owyhee, Idaho. This earth dam was completed in 1987 for the primary purpose of irrigation, with a storage capacity of 2500 acre-feet and a surface area of 347 acres. The dam is situated on the Snake River and an unnamed stream, helping to provide water resources for agricultural activities in the area.

Despite its low hazard potential, Hulet No 2 Dike has been assessed to be in poor condition as of May 2018. The dam has a hydraulic height of 8 feet and a total height of 12.5 feet, built with stone core and foundations of rock and soil. While the dam lacks a spillway, it serves its intended purpose of irrigation for the surrounding area. The risk assessment for this structure is considered high, highlighting the importance of regular inspections and maintenance to ensure its continued functionality.

The location of Hulet No 2 Dike in an area vulnerable to climate change impacts underscores the significance of water resource management and infrastructure resilience. As a state-regulated and inspected dam, it plays a vital role in supporting agricultural activities in Idaho. Continued monitoring and potential upgrades will be crucial for maintaining the safety and effectiveness of this essential water resource infrastructure in the face of evolving environmental challenges.
