East Fork Big Creek Dam E- 61 dam
East Fork Big Creek Dam E- 61
East Fork Big Creek Dam E-61, located in Harrison, Missouri, is a private earth dam designed by the USDA NRCS for flood risk reduction along the East Fork Big Creek. Completed in 2010, this dam stands at a height of 19.5 feet and has a storage capacity of 137.4 acre-feet, with a normal storage level of 35.8 acre-feet. The dam spans a length of 580 feet and has a spillway width of 40 feet to manage maximum discharges of up to 183 cubic feet per second.
Despite being privately owned, East Fork Big Creek Dam E-61 falls under the regulatory jurisdiction of the state of Missouri, with no state permits, inspections, or enforcement currently in place. The dam is classified as having a low hazard potential and a moderate risk level, with a condition assessment of "Not Rated." While the dam does not have an emergency action plan in place, it meets guidelines for risk management measures. Overall, East Fork Big Creek Dam E-61 serves as a crucial infrastructure for flood risk reduction in the area, highlighting the importance of proper dam management and monitoring for water resource and climate enthusiasts.
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- 61
Where does the data for East Fork Big Creek Dam E- 61 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.
