Hawkins, a private water resource in Idaho, is a crucial component of the state's irrigation infrastructure. Built in 1870, this earth dam on Hawkins Creek and Marsh Creek has a height of 35.1 feet and a storage capacity of 880 acre-feet. With a significant hazard potential and fair condition assessment, Hawkins is subject to frequent inspections by the Idaho Department of Water Resources to ensure its structural integrity and safety.

Managed by the Natural Resources Conservation Service, Hawkins features an uncontrolled spillway and a slide gate outlet for water release. The dam's proximity to Marsh Center in Bannock County makes it a key resource for agricultural irrigation in the region. Its moderate risk assessment of 3 highlights the importance of ongoing risk management measures to mitigate potential hazards and ensure the continued functionality of Hawkins for water supply and flood control purposes.

Located within the Walla Walla District, Hawkins plays a vital role in water management and conservation efforts in Idaho. With a drainage area of 26.6 square miles and a maximum discharge capacity of 418 cubic feet per second, this dam exemplifies the intersection of water resource management and climate resilience. As climate change impacts water availability and quality, maintaining and enhancing infrastructure like Hawkins becomes increasingly crucial for sustainable water resource management in the state.
