Summary
Built in 1911, this earth dam stands at a height of 24 feet and stretches 1434 feet in length, with a storage capacity of 650 acre-feet. Despite its low hazard potential, the dam's condition was assessed as unsatisfactory in 2016, highlighting the need for regular inspections and potential maintenance or upgrades to ensure its continued safety and functionality.
With a maximum discharge capacity of 4750 cubic feet per second and a surface area of 33 acres, Dover plays a crucial role in water resource management in the region. The dam is regulated by the Colorado Division of Water Resources, which oversees its permitting, inspection, and enforcement processes. While the risk assessment for Dover is considered moderate, efforts to mitigate potential hazards and improve risk management measures may be necessary to enhance its overall safety and resilience in the face of changing climate conditions.
Overall, Dover serves as a vital infrastructure for water supply and management, supporting agricultural irrigation and other essential needs in the area. As water resources and climate enthusiasts, it is important to monitor and advocate for the proper maintenance and regulation of dams like Dover to ensure the sustainable and efficient use of water resources for current and future generations. By staying informed and engaged in water resource issues, we can contribute to the protection and preservation of these critical assets in the face of evolving environmental challenges.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
