Ewing dam
Ewing
Ewing is a private dam located in Major County, Oklahoma, near the city of Isabella. Built in 1970, this Earth dam stands at a height of 20 feet and has a storage capacity of 100 acre-feet. The dam's primary purpose is listed as "Other", with a low hazard potential and a very high risk assessment rating. Despite being in a state of "Not Rated" condition assessment, Ewing is regulated, inspected, and enforced by the Oklahoma Water Resources Board.
Situated on TR-Deep Creek, Ewing serves as a vital structure for water resource management in the region. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 100 cubic feet per second. Although the last inspection dates back to 1997, Ewing's emergency action plan status and risk management measures are not fully documented, raising concerns about its preparedness for potential emergencies. As a significant contributor to the local water supply, ongoing monitoring and maintenance of Ewing are crucial to ensure its continued safety and effectiveness.
With its unique design elements and historical significance, Ewing stands as a testament to the importance of proper dam management in the face of changing climate conditions. As climate enthusiasts and water resource advocates continue to push for sustainable solutions, the case of Ewing serves as a reminder of the critical role that infrastructure plays in safeguarding our communities against water-related risks. By staying informed and engaged in the management of structures like Ewing, individuals can help support a more resilient and secure water future for all.

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 Ewing
Where does the data for Ewing 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.
