Colorado Parks and Wildlife Dams
Colorado Parks and Wildlife owns and operates the largest inventory of dams in the state of Colorado. The water impounded is used for purposes such as downstream irrigation, fisheries management and aquatic operations, and a multitude of recreational activities including fishing, boating and swimming.

Our Work
The average age of CPW’s High and Significant Hazard dams is 77 years. Six of these dams were constructed over 100 years ago. Most of CPW’s dams were built between 1950 and the mid-1970s. Colorado Parks and Wildlife has four 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).
Repair and rehabilitation construction was completed on several dams in 2024:
- Tarryall Dam Comprehensive Rehabilitation - Construction Manager General Contractor (CMGC) project delivery
- Dragonfly Pond Dam Comprehensive Rehabilitation
- Heart Lake Dam Outlet Valve Repairs
Completed engineering studies and designs in 2024 include:
- Meadow Creek Dam Final Design and CMGC Pre-Construction
- Garnet Mesa Dam (Sweitzer Lake) Final Design
- Big Beaver Dam (Lake Avery) Outlet Rehabilitation Final Design
- Elk Falls Dam CMGC Pre-Construction
- Lake Christine Dam Slope Stabilization and Spillway Rehabilitation Design
- Risk-Informed Prioritization of CPW's Inventory of High and Significant Hazard Dams (ongoing)
- Lake Christine Dam Construction
- Meadow Creek Dam Construction
- Garnet Mesa Dam (Sweitzer Lake) Spillway Replacement Construction
- Upper Highline Dam (Highline Lake) Spillway Rehabilitation Preliminary Design
- Big Beaver Dam (Lake Avery) Outlet Rehabilitation Construction
Ongoing work continues for smaller-scale projects involving dam maintenance, improvements, and engineering studies.
Annual Release of Upcoming Projects Anticipated over the next 2 Years
Colorado Parks & Wildlife (CPW) has a number of dam-specific projects anticipated over the next 2 years. In an effort to help engineering firms and construction contractors plan for these potential upcoming opportunities, the CPW Dam Safety Program is providing the general projects’ information below. Typically this list will be updated annually near the end of Q1. Please note that these project details are subject to change based on a number of factors such as funding and future inspections, and therefore there is no guarantee that the projects will occur as described herein. Similarly, the CPW Dam Safety Program may release additional projects during this time period that are not listed below. When a project is initiated, the solicitation will be posted on the Colorado Vendor Self Service website. Those who are interested in viewing active solicitations or registering for automatic alerts can do so at https://vss.state.co.us.
