Summary
Completed in 1965, this dam serves the primary purpose of "Other" and has a maximum storage capacity of 210 acre-feet. It is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections and enforcement.
The dam's spillway type is "Controlled" with a width of 1 foot, and it has one outlet gate. Despite being rated as having a low hazard potential, the risk assessment for Hurst Jl is considered very high. The dam is not owned or funded by any federal agency and has not undergone any modifications since its completion. Although the condition of the dam is currently not rated, it is important for water resource and climate enthusiasts to monitor its status and ensure proper risk management measures are in place.
Overall, Hurst Jl presents an intriguing case study for water resource and climate enthusiasts, with its unique design by USDA NRCS, state-regulated status, and high-risk assessment. As a privately-owned dam in Oklahoma, it highlights the importance of regular inspections and enforcement to mitigate potential hazards and ensure the safety of surrounding communities. It serves as a reminder of the critical role that infrastructure plays in water resource management and the need for proactive risk management measures in the face of changing climate patterns.

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.
