Summary

Completed in 1955, this earth dam stands at a height of 29 feet and has a maximum storage capacity of 123 acre-feet. With a normal storage capacity of 74 acre-feet and a drainage area of 1 square mile, this structure plays a crucial role in managing the flow of Kiowa Creek and reducing the risk of flooding in the surrounding area.

Managed by the Colorado Division of Water Resources, Kiowa Creek Watershed 2-G-10 has a low hazard potential and is in satisfactory condition as of the last inspection in April 2014. The dam features an uncontrolled spillway with a width of 100 feet and a maximum discharge capacity of 2345 cubic feet per second. While the structure has not been modified in recent years, it is subject to regular inspections to ensure its continued effectiveness in flood risk reduction. Overall, the risk assessment for this dam is moderate (3), highlighting the importance of ongoing monitoring and maintenance to mitigate potential hazards and safeguard the local community.

Kiowa Creek Watershed 2-G-10 serves as a vital infrastructure asset in the Kiowa area, protecting residents and properties from the threat of flooding. With its historical significance and engineering design by the Natural Resources Conservation Service, this earth dam stands as a testament to the collaborative efforts between local government and state regulatory agencies in managing water resources and climate challenges. As climate change continues to impact water systems, the role of structures like Kiowa Creek Watershed 2-G-10 becomes increasingly crucial in maintaining the resilience and sustainability of the region's water infrastructure.

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.
