About this dam

Warrenton Lake

Warrenton Lake, located in Tulsa, Oklahoma, is a privately owned earth dam constructed in 1936 by the Works Progress Administration (WPA). With a dam height of 30 feet and a length of 400 feet, the lake serves primarily for recreational purposes and has a storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections to ensure its safety and functionality.

The South Fork of Little Joe Creek feeds into Warrenton Lake, providing a surface area of 4 acres for outdoor activities. The controlled spillway with a width of 6 feet ensures proper water management and flood control. Despite being classified as a high hazard potential structure, the dam is in fair condition as of the last inspection in November 2021. The risk assessment for Warrenton Lake is very high, emphasizing the importance of proper risk management measures to mitigate potential hazards.

As a key feature in the Tulsa District and under the jurisdiction of the state of Oklahoma, Warrenton Lake stands as a vital water resource for the community. Its historical significance, combined with its recreational value and regulatory oversight, make it a noteworthy site for water resource and climate enthusiasts to appreciate and monitor for conservation and safety.

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.

FAQ

About Warrenton Lake

Where does the data for Warrenton 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.
