Big Creek-Hurricane Creek L- 6 dam
Big Creek-Hurricane Creek L- 6
Big Creek-Hurricane Creek L-6 is a local government-owned earth dam located in Carroll, Missouri, specifically in the city of DeWitt. The dam was designed by the USDA NRCS and completed in 2010 with a primary purpose of flood risk reduction along the TR-Lick Branch river or stream. Standing at a height of 24.4 feet and a length of 710 feet, the dam has a storage capacity of 212.7 acre-feet and serves a drainage area of 170.24 square miles.
Despite its low hazard potential and moderate risk assessment rating, the condition of Big Creek-Hurricane Creek L-6 is currently marked as "Not Rated" in terms of its structural integrity and maintenance. With no recent inspection date or emergency action plan in place, there is a need for ongoing monitoring and risk management to ensure the dam's effectiveness in flood risk reduction. The spillway type of the dam is uncontrolled with a width of 34 feet, allowing for a maximum discharge of 177.7 cubic feet per second.
Overall, Big Creek-Hurricane Creek L-6 plays a crucial role in mitigating flood risks in the area and protecting the surrounding communities from potential inundation. As a part of the Rock Island District, the dam stands as a testament to the collaborative efforts between local government and federal agencies in safeguarding water resources and managing climate-related risks in Missouri. Continued vigilance and maintenance will be key in ensuring the long-term functionality and safety of this important infrastructure.

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 Big Creek-Hurricane Creek L- 6
Where does the data for Big Creek-Hurricane Creek L- 6 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.
