Summary
Constructed in 1979 by the USDA NRCS, this dam serves a variety of purposes, with a primary purpose classified as "Other." With a height of 29 feet and a length of 512 feet, Mcgaha Jesse has a storage capacity of 50 acre-feet and a maximum discharge of 1375 cubic feet per second. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a low hazard potential and a risk assessment rating of "Very High (1)."
Managed by the Natural Resources Conservation Service, Mcgaha Jesse plays a crucial role in water resource management and flood control along TR LITTLE RIV in Oklahoma. Despite its relatively low hazard potential, the dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. With a controlled spillway and one outlet valve, the dam's risk management measures and emergency action plan status are not specified in the available data. The surrounding area's risk assessment suggests a very high level of concern, reflecting the importance of maintaining and monitoring this essential infrastructure for water resource and climate enthusiasts.

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.
