Farrell Lake dam
Farrell Lake
Located in Bryan, Oklahoma, Farrell Lake is a privately-owned reservoir primarily used for irrigation purposes. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Farrell Lake
Where does the data for Farrell Lake come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
