Managed by private owners, Deweese Dam is regulated and inspected by the Colorado Division of Water Resources, ensuring its safety and compliance with state regulations. The dam's spillway, with a width of 446 feet, is uncontrolled, and the dam has a high hazard potential with a satisfactory condition assessment as of the last inspection in June 2020. While the risk assessment indicates a moderate level of risk, there are no specific risk management measures or emergency action plans mentioned for the dam.
Water resource and climate enthusiasts would find Deweese Dam intriguing due to its historical significance, engineering design, and multi-purpose functionality. The dam's location along Grape Creek, its impact on the local water supply, and its risk profile highlight the importance of proper management and maintenance of such critical infrastructure. The presence of a high hazard potential and moderate risk assessment underscore the need for ongoing monitoring and potential mitigation measures to ensure the safety and reliability of Deweese Dam for the future.
