Scs-Ionine Creek Site-101 dam
Scs-Ionine Creek Site-101
SCS-Ionine Creek Site-101 in Chickasha, Oklahoma, is a state-regulated earth dam constructed in 1961 by the USDA NRCS for flood risk reduction purposes. The dam stands at 15 feet high with a hydraulic height of 11 feet and a structural height of 14 feet. It has a length of 780 feet and a storage capacity of 50 acre-feet, with a normal storage level of 25 acre-feet. The dam is located on TR-East Ionine Creek in Grady County, Oklahoma, and is under the regulatory oversight of the Oklahoma Water Resources Board (OWRB).
Despite its low hazard potential, SCS-Ionine Creek Site-101 is considered to have a very high risk level according to a rating of 1. The dam features a controlled spillway, with one valve outlet gate for water release. The last inspection of the dam was conducted in 1980, with an inspection frequency of every 5 years. The dam is currently in a not-rated condition assessment, with no emergency action plan (EAP) prepared or updated. Although the risk assessment indicates a high level of risk, the dam remains an essential infrastructure for flood risk reduction in the area and is subject to ongoing regulatory oversight and maintenance by the OWRB.
In conclusion, SCS-Ionine Creek Site-101 serves as a critical flood risk reduction structure in Grady County, Oklahoma. Despite its age and risk level, the dam continues to provide vital protection to the surrounding area. Ongoing inspections and regulatory oversight by the OWRB ensure that the dam remains in a safe and functional condition for the community. As water resource and climate enthusiasts, it is important to monitor the status of such infrastructure to ensure the safety and resilience of our water systems in the face of changing environmental conditions.

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-Ionine Creek Site-101
Where does the data for Scs-Ionine Creek Site-101 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.
