Crooked Arroyo Det Ca-1, also known as Danny Round, is a local government-owned earth dam located in La Junta, Colorado. Built in 1973 by the Soil Conservation Service, USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Crooked Arroyo-TR river or stream. With a height of 46 feet and a length of 2730 feet, the dam has a maximum storage capacity of 5754 acre-feet and covers a surface area of 204 acres.

Managed by the Colorado Department of Water Resources, Crooked Arroyo Det Ca-1 has a significant hazard potential with a fair condition assessment as of December 2018. The dam features an uncontrolled spillway with a width of 74 feet and a maximum discharge of 7250 cubic feet per second. While the risk assessment indicates a moderate level of risk, the dam is inspected every three years to ensure its structural integrity and safety measures are up to standards. The emergency action plan for the dam was last revised in June 2019, highlighting the importance of preparedness and response in the event of a disaster.
