West Fork Big Creek Dam B-166 dam
West Fork Big Creek Dam B-166
West Fork Big Creek Dam B-166, located in Pattonsburg, Missouri, is a flood risk reduction structure constructed in 1999 by the USDA NRCS. This Earth dam, with a height of 26 feet and a length of 730 feet, serves to protect the surrounding area from potential flooding events. The dam has a normal storage capacity of 26 acre-feet and a maximum storage of 109 acre-feet, with a drainage area of 90 square miles.
The dam is designed with a stone core and soil foundation, and features an uncontrolled spillway with a width of 30 feet. Despite being classified with a low hazard potential, the dam's risk assessment is moderate (3). While the dam itself is not regulated by the state of Missouri, it is owned and operated by the local government in Harrison County. With its strategic location along the TR-NOBEL BRANCH river, West Fork Big Creek Dam B-166 plays a crucial role in managing water resources and mitigating flood risks in the region.
Enthusiasts of water resource management and climate resilience will appreciate the importance of West Fork Big Creek Dam B-166 in safeguarding the community from potential flooding events. As a key infrastructure project in flood risk reduction, the dam stands as a testament to the collaborative efforts of the USDA NRCS and local government in protecting the area. With its capacity to store and manage water flow, this Earth dam serves as a vital component in the region's overall water resource infrastructure, contributing to the resilience of the surrounding ecosystem and community.

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 West Fork Big Creek Dam B-166
Where does the data for West Fork Big Creek Dam B-166 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.
