Summary

Built in 1968, this earth dam stands at a height of 192 feet and has a capacity to store up to 3,625 acre-feet of water. The reservoir covers a surface area of 63 acres and is situated along the East Fork Eagle River, ensuring a reliable water source for the surrounding area.

Managed by a public utility, Eagle Park Reservoir is regulated by the Colorado Division of Water Resources and undergoes regular inspections to ensure its safety and functionality. With a spillway width of 105 feet and a maximum discharge capacity of 1,500 cubic feet per second, the dam is equipped to handle high hazard potential scenarios. While the condition assessment currently rates as fair, risk management measures are in place to address any potential issues and ensure the reservoir continues to serve its primary purpose of water supply effectively.

Despite its age, Eagle Park Reservoir remains a crucial infrastructure in the region, providing essential water resources for residents and wildlife alike. With a moderate risk assessment rating, efforts are made to mitigate any potential hazards and ensure the continued operation and safety of this important reservoir. Its picturesque location and significant capacity make it a key feature in the water resource landscape of Colorado.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
