Summary
Built in 1970, this earth dam stands at 28 feet high and has a storage capacity of 170 acre-feet, primarily used for irrigation purposes. With a surface area of 4 acres and a controlled spillway, Stone Ralph is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its safety. Despite being classified as having low hazard potential, the dam's risk assessment is rated as very high due to its age and condition assessment not being rated.
Owned and operated by a private entity, Stone Ralph serves as a vital water resource for the surrounding area, providing irrigation water for agricultural purposes. The dam's primary purpose is to store and regulate water flow for optimal irrigation practices, with a maximum discharge capacity of 2000 cubic feet per second. Although the dam is considered to have a low hazard potential, its risk assessment is deemed very high, emphasizing the importance of regular inspections and maintenance to mitigate any potential risks associated with its aging infrastructure.
Located in Okfuskee County, Stone Ralph is part of the Tulsa District and is under the jurisdiction of the Oklahoma Water Resources Board. With a history dating back to 1970, this earth dam with stone core plays a crucial role in water management and agricultural activities in the region. Despite its low hazard potential, the dam's risk assessment indicates a high level of risk, highlighting the need for continued monitoring and evaluation to ensure the safety and functionality of this essential water resource infrastructure.

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.
