Summary
Standing at a height of 25 feet and a length of 500 feet, the dam has a storage capacity of 98 acre-feet and a surface area of 8 acres. With a low hazard potential and a very high risk assessment rating, the dam is state regulated by the Oklahoma Water Resources Board and undergoes regular inspections, permitting, and enforcement.
Despite not being rated for its condition, the dam poses a very high risk due to its location and potential impact on the surrounding area in case of failure. While it does not have a designated dam type or designer listed, the structure has a controlled spillway and is equipped with emergency action plans and contacts for mitigation in case of emergencies. With a maximum discharge of 15 cubic feet per second, the dam serves as both a recreational spot and a crucial water resource in the region.
Water resource and climate enthusiasts interested in Hamilton East Dam can explore its unique features, including its location on Sandy Creek and its regulation by the state of Oklahoma. The dam, owned privately, offers recreational opportunities while also providing essential storage for water resources in the area. With a focus on risk assessment and emergency preparedness, the dam plays a key role in both water management and safety measures for the surrounding community.

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.
