Best, also known as Trimble, is a private water resource located in Kiowa County, Colorado. This reservoir, completed in 1904, serves multiple purposes including fire protection, stock, small fish pond, and irrigation. With a dam height of 10 feet and a length of 3200 feet, Best has a storage capacity of 1422 acre-feet and a surface area of 161 acres. The reservoir is regulated by the Colorado Department of Water Resources and is inspected regularly to ensure its structural integrity.

Despite being classified as low hazard potential, Best poses a high risk due to its condition assessment being labeled as "Not Rated." The reservoir lacks an Emergency Action Plan (EAP) and has not been updated or prepared for emergency situations. However, it is reassuring to note that the state agency responsible for the regulation, inspection, and enforcement of water resources has confirmed that the dam meets state permitting requirements. With its location in Las Animas and proximity to Mustang Creek-OS, Best is a vital resource for the surrounding community and wildlife.

For water resource and climate enthusiasts, Best presents an intriguing case study of a historical earth dam that continues to serve its primary purposes despite its aging infrastructure. The reservoir's risk assessment and lack of an EAP highlight the importance of regular maintenance and emergency preparedness for water storage facilities. As climate change impacts water availability and quality, ensuring the safety and reliability of reservoirs like Best becomes increasingly crucial in sustaining ecosystems and communities that depend on them.
