Summary

Built in 1936, this private-owned structure stands at a height of 7 feet and has a storage capacity of 137 acre-feet, with a normal storage level of 40 acre-feet. Situated along the Threemile Creek-OS river or stream, it plays a crucial role in irrigation activities in the region, highlighting its importance in water resource management.

Despite its low hazard potential, the Hunter dam remains regulated and inspected by the Colorado Division of Water Resources. The dam's primary purpose for fire protection and stock maintenance underscores its significance in ensuring water availability for agricultural and environmental needs in the area. With a risk assessment rating of "High (2)", there is a clear recognition of the importance of managing and maintaining this structure to mitigate potential risks and ensure its longevity in safeguarding water resources in the region.

The Hunter dam, with its earth-type construction and 800-foot length, is a key component of the water infrastructure in Jackson County. While currently rated as "Not Rated" in terms of its condition assessment, ongoing inspections and regulatory oversight ensure its continued functionality. As climate change impacts water availability, this dam's role in providing essential water resources for various purposes underscores the need for proactive management and maintenance to address potential risks and ensure sustainable water management practices in the face of changing environmental conditions.

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.
