Summary

This earth dam stands at a height of 25 feet and spans 370 feet in length, with a hydraulic height of 27 feet and a structural height of 29 feet. It serves the primary purpose of flood risk reduction, with a maximum storage capacity of 36 acre-feet and a normal storage of 22 acre-feet. The dam, situated on Kiowa Creek, is regulated by the Colorado Division of Water Resources and undergoes regular inspections, with its condition assessed as fair.

The Kiowa Creek Watershed 3-D-30 dam, overseen by local government authorities, has a low hazard potential and a moderate risk assessment rating. The spillway, which is uncontrolled, has a width of 60 feet to manage a maximum discharge of 1200 cubic feet per second. While the dam has not been modified in recent years, it is important to note that it is subject to regular inspection and enforcement by the state regulatory agency. The surrounding area is at a moderate risk level (3) in terms of potential hazards, emphasizing the importance of proper risk management measures and emergency preparedness.

Overall, Kiowa Creek Watershed 3-D-30 serves as a vital infrastructure for flood risk reduction in the region, safeguarding against potential inundation and offering protection to the local community. With its fair condition assessment and regular inspections, this earth dam stands as a testament to effective water resource management and climate resilience efforts in Elbert County, Colorado. As water resource and climate enthusiasts, it is crucial to recognize the significance of such structures in ensuring the safety and sustainability of our natural environment.

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.
