East Fork Big Creek Dam E- 27 dam
East Fork Big Creek Dam E- 27
East Fork Big Creek Dam E-27, also known as Site E-27, is a local government-owned earth dam located in Bethany, Missouri. Designed by the USDA NRCS and completed in 1990, this dam serves the primary purpose of flood risk reduction along the East Fork Big Creek. Standing at 27 feet tall with a length of 440 feet, the dam has a storage capacity of 76 acre-feet and covers a surface area of 8 acres.
With a low hazard potential and a moderate risk assessment rating, East Fork Big Creek Dam E-27 plays a crucial role in mitigating flood risks in the region. The dam features an uncontrolled spillway with a width of 16 feet and has not been modified since its completion. While the condition assessment is currently not rated, the dam is not regulated by the state and does not require regular inspections, indicating a stable and well-maintained structure.
For water resource and climate enthusiasts, East Fork Big Creek Dam E-27 presents an interesting case study of a locally-owned flood control infrastructure in Missouri. With its strategic location and design by the USDA NRCS, this dam serves as a vital component in managing flood risks along the East Fork Big Creek, showcasing the importance of effective water management strategies in mitigating natural disasters and protecting communities.
Dam data reference
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 East Fork Big Creek Dam E- 27
Where does the data for East Fork Big Creek Dam E- 27 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.
