Summary
Constructed in 1972 by the USDA NRCS, this Earth dam stands at 22 feet high and spans 506 feet in length, with a storage capacity of 86 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections and enforcement to ensure its safety and compliance.
With a low hazard potential and a very high risk assessment rating, Farrell Lake is equipped with a controlled spillway and a single outlet valve. Despite being in a rural area near the TR-J-N Creek, the lake's surface area covers 11 acres and offers a vital water source for agricultural activities in the region. Congressman Markwayne Mullin represents the area where Farrell Lake is situated, within the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.
Although the condition of Farrell Lake has not been officially rated, its risk management measures and emergency action plans are under scrutiny to ensure the safety of the surrounding community. With its modest storage capacity and strategic location for irrigation, Farrell Lake plays a crucial role in water resource management in Bryan, Oklahoma, making it a key asset for climate and water resource enthusiasts in the region.

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.
