Summary
Managed by a private owner, the dam stands at a height of 22.2 feet with a hydraulic height of 19 feet. The dam's primary purpose is for irrigation, providing a storage capacity of 57 acre-feet and covering a surface area of 6.5 acres.
Constructed primarily with earth and stone materials, Dewitt Gaddy Dam is classified as having a low hazard potential and fair condition assessment. Despite being uncontrolled, the dam has a spillway type and outlet gates to regulate water flow. With a moderate risk assessment rating, the dam is regularly inspected and deemed to meet safety guidelines. The dam's location on Mill Creek-Tr contributes to a drainage area of 95 square miles, with a maximum discharge of 142 cubic feet per second.
Water resource and climate enthusiasts will appreciate the importance of Dewitt Gaddy Dam in sustaining agricultural activities in the region. Its construction by the USDA NRCS underscores the collaboration between private entities and government agencies to enhance water management infrastructure. As a key component of the local irrigation system, the dam plays a crucial role in ensuring water supply reliability and supporting sustainable farming practices.

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.
