Regal Lake dam
Regal Lake
Regal Lake, located in Oklahoma City, is a privately owned recreational reservoir with a rich history dating back to its completion in 1920. Managed by the Thurman Engineering firm, this picturesque lake sits on Spring Creek and offers a serene escape for water resource and climate enthusiasts alike. With a dam height of 16 feet and a storage capacity of 81 acre-feet, Regal Lake provides ample opportunity for outdoor activities such as fishing, boating, and wildlife observation.
Despite its scenic beauty, Regal Lake poses a high hazard potential due to its poor condition assessment and very high risk rating. The dam, primarily constructed of earth and stone materials, has a controlled spillway and a maximum discharge capacity of 6,320 cubic feet per second. While the lake's primary purpose is for recreation, its critical infrastructure demands regular inspection, enforcement, and regulatory oversight by the Oklahoma Water Resources Board to ensure public safety and environmental sustainability.
As a cherished recreational spot in Oklahoma, Regal Lake serves as a vital water resource for the local community while also posing significant risks that require diligent management and mitigation strategies. Its unique combination of historical significance, natural beauty, and regulatory complexities make it a fascinating case study for water resource and climate enthusiasts seeking to understand the delicate balance between human enjoyment and environmental stewardship in today's changing climate landscape.

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 Regal Lake
Where does the data for Regal 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.
