Summary
Built in 1978 by the USDA NRCS, this earth dam stands at a height of 22 feet and has a maximum storage capacity of 236 acre-feet. The primary purpose of Lunt is for irrigation, with a spillway type classified as "Controlled" and a hazard potential rated as "Low".
Managed by the OWRB, Lunt is subject to state regulation, permitting, inspection, and enforcement. Despite being classified as having a low hazard potential, the risk assessment for this dam is rated as "Very High (1)". With a controlled spillway width of 1 foot and a maximum discharge capacity of 279 cubic feet per second, it is crucial for stakeholders to monitor and maintain this structure to ensure the safety of downstream communities and water resources along TR-ISLAND BAYOU.
As a key water resource in the area, Lunt plays a vital role in supporting agricultural activities through irrigation. With its strategic location and design, it serves as a critical infrastructure for water management in Bryan, Oklahoma. However, given the high risk assessment, stakeholders must prioritize regular inspections, maintenance, and emergency preparedness to mitigate potential hazards and safeguard the surrounding environment.

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.
