Scs-Whitegrass-Waterhole Cr Site-6 dam
Scs-Whitegrass-Waterhole Cr Site-6
SCS-Whitegrass-Waterhole Cr Site-6 is a state-regulated dam located in McCurtain, Oklahoma, with a primary purpose of flood risk reduction. Built in 1961 by the USDA NRCS, this earth dam stands at a height of 35 feet and stretches 1300 feet in length, providing a maximum storage capacity of 4143 acre-feet. The dam is equipped with a controlled spillway and a single valve outlet gate for water management.
Despite its low hazard potential, SCS-Whitegrass-Waterhole Cr Site-6 is classified as having a very high risk due to its location and structural characteristics, receiving a risk assessment rating of 1. While the dam's condition is currently not rated, it undergoes inspections every five years to ensure its integrity and safety. The Fort Worth District of the USACE has no involvement with this dam, as it is owned and managed solely by the state of Oklahoma through the OWRB.
Water resource and climate enthusiasts would find SCS-Whitegrass-Waterhole Cr Site-6 to be an intriguing case study of a state-regulated dam designed for flood risk reduction in a high-risk area. Its historical construction by the USDA NRCS, along with its impressive storage capacity and controlled spillway system, highlight the importance of effective water management infrastructure in mitigating potential flooding events. The ongoing inspections and state oversight further emphasize the commitment to maintaining the dam's safety and functionality for the surrounding community in Iron Stob Corner.

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 Scs-Whitegrass-Waterhole Cr Site-6
Where does the data for Scs-Whitegrass-Waterhole Cr Site-6 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.
