The Coal Bank Watershed Cb-1 is a federal-owned structure located in Weld County, Colorado, specifically in the city of Eaton. This watershed is regulated by the Colorado Department of Water Resources and serves the primary purpose of flood risk reduction. Completed in 1961, the Earth-type dam stands at 51 feet high with a hydraulic height of 51 feet and a structural height of 64 feet, spanning a length of 2544 feet. It has a maximum storage capacity of 2754 acre-feet and covers a drainage area of 27 square miles, with a spillway width of 302 feet for uncontrolled discharge.

Despite being classified as having a low hazard potential and being in a satisfactory condition as of the last assessment in 2016, the Coal Bank Watershed Cb-1 still poses a moderate risk. It is subject to regular inspections every three years to ensure its safety and effectiveness in flood prevention. The structure, designed by the USDA NRCS, plays a crucial role in managing water resources in the area and protecting the surrounding communities from potential flooding events. As water resource and climate enthusiasts, understanding and monitoring the operations and maintenance of structures like the Coal Bank Watershed Cb-1 is essential for sustainable water management practices and mitigation of climate-related risks.
