Summary

Built in 1950, this earth dam stands at 27 feet high and serves multiple purposes including irrigation, recreation, and water supply. With a storage capacity of 144 acre-feet, Reynolds Creek is the primary water source for this reservoir, which covers a surface area of 15 acres.

Managed by the Colorado Division of Water Resources, Reynolds Dam has a low hazard potential and is in fair condition as of the last inspection in October 2011. The dam features a slide gate and uncontrolled outlet gates, but lacks a spillway. Despite its age, Reynolds Dam has been deemed to meet guidelines for emergency action plans, although risk assessments indicate a high risk level (2). With a history of state regulation and maintenance, Reynolds Dam remains a vital resource for water management in the Hotchkiss area.

Overall, Reynolds embodies a blend of historical significance and practical utility in the realm of water resource management. Its role in providing irrigation water and recreational opportunities underscores the importance of maintaining and monitoring aging infrastructure to ensure the safety and sustainability of water resources in the region. As climate change continues to impact water availability and quality, structures like Reynolds play a crucial role in adapting to evolving environmental challenges and securing water supplies for future generations.

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.
