Gregg Winters dam
Gregg Winters
Gregg Winters is a privately owned dam located in Jackson, Oklahoma, along the North Fork of the Red River. Constructed in 1996, this Earth type dam stands at a height of 27 feet and serves a variety of purposes beyond flood control, with a storage capacity of 172 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its structural integrity and safety.
Despite its low hazard potential, Gregg Winters is classified as having a very high risk factor, emphasizing the importance of ongoing risk management measures and emergency preparedness. The dam features a controlled spillway and a single valve outlet gate for water release. The area surrounding the dam has a drainage area of 960 square miles and a maximum discharge capacity of 331 cubic feet per second, making it a crucial part of the local water resource infrastructure.
Located within the Tulsa District of the US Army Corps of Engineers, Gregg Winters is a significant asset in water resource management for the region. With its strategic position along the North Fork of the Red River, this dam plays a vital role in flood control, water storage, and overall environmental protection efforts. Enthusiasts interested in water resources and climate will find Gregg Winters to be a fascinating case study in dam design, regulation, and risk assessment.

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 Gregg Winters
Where does the data for Gregg Winters 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.
