Our Work

Colorado Parks and Wildlife has three full-time Dam Safety Engineers who, with the help of other dedicated staff located around the state, manage all the work and monitoring on CPW’s dams. They perform regular dam safety inspections on all CPW-owned dams and maintain current Emergency Action Plans for First Responders.

Dam Repairs and Maintenance

Public Safety is Our First Priority

Public infrastructure and population centers are often located downstream, which increases the likelihood of devastating consequences in the event of a dam failure. Maintenance and rehabilitation of CPW’s dams is of paramount importance to CPW.

    In 2014, CPW undertook a Screening Level Risk Analysis (SLRA) to provide an overview of the condition of CPW dams and develop a repair and rehabilitation priority list. Since that time, CPW has made extensive progress on achieving those necessary improvements. CPW is currently working through an update to the conditional assessment and prioritization list, to update and enhance the SLRA (started in 2023 and planned to be complete in early 2025).

    • Rito Hondo Dam Comprehensive Rehabilitation - Construction Manager General Contractor (CMGC) project delivery
