Constructed in 1925, this earthen dam stands at a height of 25 feet and has a maximum storage capacity of 194 acre-feet. With a primary purpose of irrigation, the dam plays a crucial role in water supply for the surrounding area, storing up to 131 acre-feet of water during normal conditions.
Despite being classified as having a low hazard potential and a satisfactory condition assessment, Hanson #2 is also considered to have a high risk level (2) based on the data provided. The dam features a spillway width of 12 feet and is equipped with slide and uncontrolled outlet gates. Its last inspection was conducted in September 2020, with inspections scheduled every 6 years. While the dam does not have an Emergency Action Plan (EAP) prepared, it meets regulatory guidelines and is subject to state permitting, inspection, and enforcement.
For water resource and climate enthusiasts, Hanson #2 serves as a fascinating example of early 20th-century engineering for irrigation purposes. Its location in Delta County, Colorado, within the Omaha District, highlights the importance of maintaining and monitoring aging infrastructure to ensure the safety and security of water resources in the region. As climate change impacts water availability and usage patterns, understanding and safeguarding dams like Hanson #2 become increasingly critical for sustainable water management practices.
