Godfrey Jack dam
Godfrey Jack
Godfrey Jack is a private earth dam located in Marshall, Oklahoma, with a primary purpose of recreation. Completed in 1960, this dam stands at a height of 45 feet and has a storage capacity of 159 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a low hazard potential and a very high risk assessment rating.
Situated on the TR WHISKEY CR river, Godfrey Jack offers a surface area of 38 acres for recreational activities. The dam features a controlled spillway and a single valve outlet gate. Despite not being rated for its condition assessment, the dam poses a minimal risk due to its low hazard potential. The surrounding area, represented by Congressman Markwayne Mullin, enjoys the benefits of this well-maintained water resource.
In the realm of water resource and climate management, Godfrey Jack serves as a vital recreational hub in Marshall, Oklahoma. With its regulated state jurisdiction and adherence to inspection protocols, the dam stands as a testament to responsible water infrastructure. Enthusiasts and stakeholders in water resource and climate conservation can appreciate the importance of maintaining the integrity and safety of structures like Godfrey Jack for the well-being of the community and the environment.

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 Godfrey Jack
Where does the data for Godfrey Jack 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.
