Summary
Built in 1940, this Earth dam stands at 38 feet tall with a hydraulic height of 32 feet and a length of 250 feet. Its primary purpose is for fire protection, stock, and as a small fish pond, with a storage capacity of 510 acre-feet and a surface area of 18 acres. The dam is state-regulated, with the Department of Natural Resources and Conservation (DNRC) overseeing its permitting, inspection, and enforcement.
Despite being classified as low hazard potential, Sugar has not been rated for its condition assessment. The dam has not undergone any modifications over the years and lacks specific details on its drainage area, spillway type, and max discharge. As a water resource and climate enthusiast, the lack of comprehensive data on Sugar sparks curiosity and raises questions about its overall risk management measures, emergency action plan preparation, and whether it meets current safety guidelines. As a vital structure for fire protection and wildlife conservation in the area, it is essential to ensure proper maintenance and monitoring of Sugar to prevent any potential hazards or failures in the future.

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.
