Summary

Built in 1964, this Earth-type dam stands at a height of 56 feet and has a storage capacity of 1,547 acre-feet, primarily used for water supply purposes. The dam is regulated by the Colorado Department of Water Resources and undergoes regular inspections to ensure its structural integrity.

The dam's spillway, with a width of 245 feet, is of the uncontrolled type, allowing for the release of excess water during periods of high discharge. While the dam's hazard potential is rated as high, its condition assessment is deemed satisfactory. In the event of an emergency, the dam is equipped with a slide gate outlet for controlled water release. With a moderate risk assessment score of 3, the dam's risk management measures and emergency action plan are critical components in ensuring the safety of downstream communities and the surrounding environment.

Jerry Creek #1 serves as a vital water resource infrastructure in the region, supporting agriculture, municipal, and industrial water needs. Its presence along the Plateau Creek helps in regulating water flow and providing necessary storage for times of water scarcity. As climate change impacts water availability, the proper maintenance and management of dams like Jerry Creek #1 become increasingly important in ensuring sustainable water resource management for the future.

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.
