Summary
Completed in 1899, this dam stands at 15 feet tall and spans 250 feet in length, providing a storage capacity of 230 acre-feet for agricultural use. Despite its age, Antelope has a satisfactory condition assessment and a low hazard potential, making it a reliable water resource for the surrounding area.
Managed by the local government and regulated by the Colorado Division of Water Resources, Antelope undergoes regular inspections every six years to ensure its structural integrity and safety. With a maximum discharge of 200 cubic feet per second and a spillway width of 200 feet, this dam is equipped to handle high-risk situations and protect downstream areas in the event of an emergency. The dam's location in Hardin, Colorado, along with its compliance with state permitting and enforcement requirements, demonstrates a commitment to water resource management and climate resilience in the region.
Antelope serves as a vital piece of infrastructure for the community, balancing the needs of irrigation with the importance of environmental stewardship. With a history dating back over a century, this earth dam continues to play a crucial role in water management along Spring Creek, showcasing the intersection of engineering ingenuity, natural resource conservation, and climate adaptation in the Colorado landscape.

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.
