East Fork Big Creek Dam E- 76 dam
East Fork Big Creek Dam E- 76
East Fork Big Creek Dam E- 76, also known as Str E-76, is a flood risk reduction structure located in Harrison, Missouri. Built in 1986 by the USDA NRCS, this earth dam stands at 29 feet high and spans 600 feet in length along the East Fork Big Creek. With a storage capacity of 149 acre-feet and a drainage area of 161.92 square miles, the dam serves a primary purpose of flood risk reduction to protect the surrounding area from potential water overflow.
Despite being non-federally regulated, East Fork Big Creek Dam E- 76 has a low hazard potential and a moderate risk assessment rating. The dam's spillway, which is uncontrolled and 40 feet wide, helps manage excess water flow during heavy rainfall events. While the dam's condition is currently not rated, its structural integrity and risk management measures are closely monitored by the local government to ensure the safety of nearby residents and infrastructure. With no outlet gates and a small surface area of 5 acres, this dam plays a crucial role in mitigating flood risks in the region.
Although East Fork Big Creek Dam E- 76 does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, its risk assessment indicates a moderate level of risk (3 out of 5). With no associated locks or inspection frequency listed, it is apparent that this dam primarily relies on its design and construction quality to maintain its function. As a key flood risk reduction asset in the area, the dam's importance lies in its ability to protect the local community from potential water-related disasters.

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- 76
Where does the data for East Fork Big Creek Dam E- 76 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.
