Summary

Constructed in 2000 by MUETING ENGINEERING & SURVEYING, the dam stands at 22 feet tall and stretches 590 feet in length, with a storage capacity of 72 acre-feet. Despite being unlisted by federal agencies and having no state regulation or inspection, the dam has a low hazard potential and is considered to have moderate risk, with a maximum discharge of 555 cubic feet per second.

With a surface area of 3.4 acres and a drainage area of 0.22 square miles, Dd No 200 serves as a vital structure in mitigating flood risks in the region. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. Although its condition is currently not rated, the dam is assessed to meet guidelines for emergency action plans. Overall, Dd No 200 plays a crucial role in protecting the local community from potential flooding events, showcasing the importance of proper water resource management and climate resilience strategies in safeguarding vulnerable areas.

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.
