Anderson Brothers #1, also known as Labbe #3, is a privately owned earth dam located in Mesa County, Colorado. Built in 1940 for irrigation purposes on Leon Creek, this structure stands at a height of 27 feet with a length of 775 feet, providing a storage capacity of 387 acre-feet. The dam underwent modifications in 1952 to enhance its hydraulic, mechanical, and structural features, ensuring its continued effectiveness in water management.

The dam's spillway, with a width of 100 feet, is uncontrolled, and it has a low hazard potential with a fair condition assessment as of the last inspection in July 2015. The risk assessment for Anderson Brothers #1 indicates a moderate level of risk, prompting the need for ongoing monitoring and maintenance efforts. Despite its age, the dam serves as a vital asset for the local irrigation system, highlighting the importance of sustainable water resource management in the face of changing climate conditions. With the involvement of the Natural Resources Conservation Service in its design, Anderson Brothers #1 stands as a testament to collaborative efforts in safeguarding water resources for future generations.
