Scs-Stillwater Creek Site-40 dam
Scs-Stillwater Creek Site-40
SCS-Stillwater Creek Site-40, also known as Mcmurtry Lake, is a state-owned structure located in Noble, Oklahoma, specifically in Stillwater. This earth dam was completed in 1971 and serves primarily as a water supply source for the area. Standing at 64 feet tall with a length of 3039 feet, the dam has a storage capacity of 24,726 acre-feet and a surface area of 1155 acres, drawing water from a drainage area of 25 square miles.
Managed by the USDA NRCS, this dam on the North Stillwater Creek is regulated by the OWRB and meets state permitting, inspection, and enforcement requirements. The spillway is designed to be controlled with a width of 4 feet, and the dam poses a high hazard potential due to its condition assessment being fair. While the risk assessment is very high, emergency action plans and management measures are not explicitly detailed in the available data, indicating potential areas for further development and improvement in risk mitigation strategies.
Despite its age, SCS-Stillwater Creek Site-40 continues to play a crucial role in water resource management for the region, emphasizing the importance of maintaining and monitoring its structural integrity and risk management protocols. As climate change poses increasing challenges to water availability and quality, the significance of such water supply infrastructure becomes even more pronounced, underlining the need for proactive measures to ensure the resilience and sustainability of our water resources in the face of a changing climate.

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-Stillwater Creek Site-40
Where does the data for Scs-Stillwater Creek Site-40 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.
