Summary
Built in 1998 by USDA NRCS, this Earth-type dam stands at a height of 47.6 feet with a storage capacity of 94.55 acre-feet. The dam serves as a crucial structure on Flying Creek, providing flood control and water storage for the surrounding area.
Despite being rated as having a low hazard potential, the dam is classified as being at very high risk due to its condition assessment not being rated. With only one valve for outlet gates and a controlled spillway, the dam requires regular inspections which are mandated every five years. The risk mitigation measures and emergency action plan for the dam are not clearly outlined, highlighting the need for improved management and preparedness in case of any unforeseen events.
For water resource and climate enthusiasts, Mike Wilson Gss 1 presents an intriguing case study in dam management and risk assessment. With its location in Roger Mills County and the potential impact on the surrounding area in case of failure, this dam serves as a reminder of the importance of proper maintenance and monitoring of critical infrastructure in the face of changing environmental conditions.

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.
