Summary
Designed by USDA NRCS, this earth dam stands at a height of 32 feet and has a length of 420 feet. Completed in 1961, it serves the primary purpose of flood risk reduction and debris control in the area. With a low hazard potential and moderate risk assessment rating, this gully plug plays a crucial role in managing water resources in the region.
Managed and funded by the Natural Resources Conservation Service, Ionine Creek Gully Plug #1 has a normal storage capacity of 1 acre-foot and a maximum storage of 15 acre-feet. Despite its age, the dam's condition assessment data is not available, pointing to the need for further inspection and evaluation. The structure features an uncontrolled spillway with a width of 20 feet, ensuring effective water discharge during high flow events. With a drainage area of 0.12 square miles, this gully plug plays a vital role in protecting the surrounding areas from flooding and erosion.
Located in Grady County, Oklahoma, Ionine Creek Gully Plug #1 stands as a testament to effective water resource management and climate resilience efforts in the region. With its strategic design and purposeful construction, this structure continues to safeguard the local community against the impacts of extreme weather events. As climate enthusiasts and water resource professionals, understanding and monitoring the performance of such vital infrastructure is essential for ensuring the sustainable management of our natural resources.

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.
