West Fork Big Creek Dam B-108 dam
West Fork Big Creek Dam B-108
West Fork Big Creek Dam B-108 is a vital structure located in Harrison, Missouri, built in 1991 by the USDA NRCS for flood risk reduction purposes. This earth dam stands at a height of 26.4 feet, with a hydraulic height of 26 feet and a structural height of 27 feet. It spans 380 feet in length and has a storage capacity of 64 acre-feet, serving a drainage area of 140 square miles. Despite its moderate risk assessment rating of 3, the dam is considered to have low hazard potential, making it a crucial asset for the local government in Bethany.
Managed by the Natural Resources Conservation Service, West Fork Big Creek Dam B-108 has no associated structures and features an uncontrolled spillway with a width of 32 feet. While its condition is currently not rated, the dam has not undergone any modifications since its completion. With no outlet gates and a surface area of 5 acres, the dam remains a key component in the area's flood risk reduction strategy. Although it is not regulated by the state and does not have an emergency action plan in place, the dam plays a significant role in protecting the surrounding community from potential flooding events.
Situated in the Rock Island District and owned by the local government, West Fork Big Creek Dam B-108 exemplifies the collaborative efforts between federal agencies and local authorities in managing water resources. Despite its unassuming hazard potential, the dam's strategic location along the TR-WEST FORK BIG CREEK underscores its importance in safeguarding the region against flooding risks. As climate enthusiasts and water resource professionals continue to monitor and assess the dam's condition, its role in flood risk reduction remains indispensable for the safety and well-being of the residents in Harrison, Missouri.

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-108
Where does the data for West Fork Big Creek Dam B-108 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.
