Summary

Built in 1958 by the USDA NRCS, this earth dam stands at a height of 28 feet and has a hydraulic height of 30 feet, providing protection to the surrounding area from potential flooding events. With a storage capacity of 430 acre-feet and a maximum discharge rate of 9083 cubic feet per second, this dam plays a crucial role in managing water resources in the region.

The dam, situated on Kiowa Creek, covers a drainage area of 4 square miles and has a spillway width of 200 feet for uncontrolled overflow. Despite being classified as having a low hazard potential, the structure is reported to be in fair condition as of the last inspection date in October 2020. With a moderate risk assessment rating of 3, ongoing risk management measures are likely in place to ensure the continued safety and effectiveness of the dam in mitigating flood risks for the local community.

Overall, Kiowa Creek Watershed 1-P-10 serves as a vital infrastructure asset for flood control in the area, with its construction and maintenance overseen by the local government and regulatory agencies. Its strategic location and design parameters make it a significant component of the water resource management system in Elbert County, highlighting the importance of sustainable infrastructure for climate resilience and disaster preparedness in the region.

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.
