Summary
Completed in 1957, this dam stands at a height of 28 feet and stretches 1000 feet in length, with a storage capacity of 333 acre-feet and a maximum discharge of 4560 cubic feet per second. The spillway, controlled by a 1-foot wide structure, helps manage water flow during periods of high precipitation, showcasing the importance of effective water resource management in mitigating flood risks.
Despite being rated as having a high hazard potential, SCS-Cavalry Creek Site-20 is assessed to be in fair condition. The dam's emergency action plan status remains unclear, highlighting the need for updated risk management measures. With a very high risk rating and the presence of a spillway for controlled water release, this site underscores the critical role of infrastructure in protecting communities from potential flooding events. As climate change continues to impact precipitation patterns, the maintenance and monitoring of dams like SCS-Cavalry Creek Site-20 are vital for safeguarding water resources and enhancing climate resilience in the region.
Managed by the Natural Resources Conservation Service, this earth dam serves as a key component of flood risk reduction efforts in the area. With a primary purpose of flood risk reduction, SCS-Cavalry Creek Site-20 plays a crucial role in regulating water flow and protecting downstream areas from inundation. As part of the state-regulated infrastructure, this dam exemplifies the collaborative efforts between government agencies and local communities to ensure the sustainable management of water resources and adaptation to changing climate conditions.

Dam Data Reference
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.
