Scs-Stillwater Creek Site-12 dam
Scs-Stillwater Creek Site-12
SCS-Stillwater Creek Site-12 is a state-regulated dam located in Payne County, Oklahoma, specifically in the city of MEHAN. The dam was designed by the USDA NRCS and completed in 1987 for the primary purpose of flood risk reduction along the TR STILLWATER CREEK. This earth dam stands at a height of 30 feet and has a length of 1075 feet, with a storage capacity of 910 acre-feet and a normal storage capacity of 82 acre-feet.
The dam has a controlled spillway type with a width of 1 foot and is equipped with a valve outlet gate. Despite being rated as having a low hazard potential, the dam is considered to have a very high risk level (1) based on the risk assessment. It is under state jurisdiction and regulation by the Oklahoma Water Resources Board (OWRB), with permitting, inspection, and enforcement responsibilities managed by the state agency. The dam is regularly inspected every 5 years, with the last inspection recorded in 1980 and the condition currently assessed as not rated.
Overall, SCS-Stillwater Creek Site-12 serves as an important infrastructure for flood risk reduction in the region, ensuring the protection of local communities and properties from potential water-related disasters. As a part of the state's water resource management efforts, this dam plays a crucial role in managing water flow, storage, and discharge along the TR STILLWATER CREEK, contributing to the overall resilience of the area against floods and other hydrological risks. Climate and water resource enthusiasts can appreciate the technical details and management aspects of this dam, as well as its significance in enhancing the safety and sustainability of the local 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 Scs-Stillwater Creek Site-12
Where does the data for Scs-Stillwater Creek Site-12 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.
