Webb dam
Webb
Webb, located in Bryan County, Oklahoma, is a privately owned earth dam constructed in 1975 by the USDA NRCS. This structure, with a height of 20 feet and a length of 700 feet, serves multiple purposes and is regulated by the Oklahoma Water Resources Board. The dam has a low hazard potential and a very high risk assessment rating, indicating the importance of monitoring and maintenance to ensure its safety and functionality.
With a maximum storage capacity of 59 acre-feet and a normal storage of 53 acre-feet, Webb plays a crucial role in water resource management for the area, specifically in the Rock Creek watershed. The dam features a controlled spillway and one valve outlet gate for controlled water release. Despite being last inspected in 2004, the dam has not been rated for its current condition, highlighting the need for a thorough assessment to determine any necessary maintenance or improvements to mitigate risks associated with its aging infrastructure.
As a significant water management structure in the region, Webb's design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water resource practices. With its state-regulated status and the potential impact of its failure on downstream communities, continued monitoring and adherence to regulatory guidelines are essential to ensure the safety and integrity of this vital infrastructure in Bryan County, Oklahoma.

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 Webb
Where does the data for Webb 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.
