Summary
This earth dam structure, designed by the USDA NRCS in 1963, serves multiple purposes including fire protection, stock watering, and flood risk reduction. With a low hazard potential and a moderate risk assessment rating, this dam provides a storage capacity of 82 acre-feet and covers a surface area of 5 acres.
The dam, situated on the TR-Maple River, has a drainage area of 0.59 square miles and a maximum discharge capacity of 0 cubic feet per second. Despite its uncontrolled spillway type, the dam's condition assessment is currently not rated, signaling a need for further evaluation. With a structural height of 0 feet and a hydraulic height of 0 feet, the dam stands at 38 feet tall and has a normal storage capacity of 32 acre-feet. The risk management measures and emergency action plan for this dam are yet to be fully documented, highlighting the need for continued monitoring and assessment to ensure the safety and effectiveness of this vital water resource.

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.
