Scs-Waterfall-Gilford Creek Site-11 dam
Scs-Waterfall-Gilford Creek Site-11
Located in McCurtain County, Oklahoma, the SCS-Waterfall-Gilford Creek Site-11 is a state-regulated dam with a primary purpose of flood risk reduction. Constructed in 1980 by the USDA NRCS, this earth dam stands at a height of 31 feet and spans 1520 feet in length. With a storage capacity of 1100 acre-feet and a normal storage of 96 acre-feet, it serves as a crucial structure for managing water resources in the area.
Situated on TR-Harris Bayou in Harris, Oklahoma, this dam is owned by the state and regulated by the Oklahoma Water Resources Board. It features a controlled spillway and one valve outlet gate, with a hazard potential rated as low. Despite being constructed over four decades ago, the condition assessment of the dam is currently marked as "Not Rated," highlighting the need for ongoing monitoring and maintenance to ensure its effectiveness in flood risk reduction. Water resource and climate enthusiasts can appreciate the engineering marvel of this dam and its role in safeguarding the surrounding communities from potential flooding events.
As a part of the flood risk reduction infrastructure in McCurtain County, the SCS-Waterfall-Gilford Creek Site-11 plays a critical role in water management and protection. With a drainage area of 2.3 square miles and a maximum discharge capacity of 1553 cubic feet per second, this dam serves as a vital line of defense against potential flood hazards. Despite its low hazard potential, ongoing inspection and maintenance are essential to ensure the continued safety and effectiveness of this important water resource management structure.

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-Waterfall-Gilford Creek Site-11
Where does the data for Scs-Waterfall-Gilford Creek Site-11 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.
