Summary
Constructed by the USDA NRCS in 1978, this dam stands at a height of 9 feet and has a storage capacity of 65 acre-feet, with a maximum discharge of 7 cubic feet per second. The spillway type is uncontrolled, with a spillway width of 1 foot, and there are no associated locks for navigation.
With a low hazard potential and a moderate risk assessment rating, Gaylon Williams Lake has not been rated for its condition assessment. Despite not having a designated emergency action plan or updated inundation maps, this dam plays a crucial role in managing flood risks in the Montgomery County area. The dam is owned by a private entity and is not regulated by the state, indicating the importance of private ownership in water resource management and climate resilience efforts.
Overall, Gaylon Williams Lake stands as a testament to the collaborative efforts between private owners and government agencies in mitigating flood risks and protecting communities from potential disasters. As an essential infrastructure for flood risk reduction, this earth dam serves as a valuable resource for water resource and climate enthusiasts interested in understanding the intersection of public and private interests in managing water resources effectively.

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.
