Langston Lake dam
Langston Lake
Langston Lake, located in Langston, Oklahoma, is a state-owned water supply reservoir with a primary purpose of providing water to the surrounding area. Built in 1966 by Collins, Flood & Associates, this earth dam structure stands at a height of 65 feet and has a storage capacity of 7,720 acre-feet. With a surface area of 420 acres and a drainage area of 6 square miles, Langston Lake plays a crucial role in managing water resources in the region.
Despite its fair condition assessment and high hazard potential, Langston Lake continues to serve as a vital water source for the community. The dam features a controlled spillway with a width of 4 feet and a slide gate outlet. With a maximum discharge capacity of 80,080 cubic feet per second, the reservoir is well-equipped to handle potential flood events. Maintained and regulated by the Oklahoma Water Resources Board, Langston Lake remains a key component of the local water infrastructure, ensuring water supply reliability and flood control measures are in place.
As an essential water resource in Logan County, Langston Lake stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions. With a very high risk assessment rating and a designated emergency action plan, the reservoir is prepared to address potential risks and ensure the safety of the surrounding community. Langston Lake serves as a valuable asset in water supply management and environmental stewardship, highlighting the critical role that water resources play in the sustainability of our ecosystems and communities.

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 Langston Lake
Where does the data for Langston 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 High 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.
