Summary
Built in 2010 by the USDA NRCS, this earth dam stands at a height of 21.6 feet and has a storage capacity of 185.5 acre-feet. The primary purpose of the dam is to mitigate flooding along the tributary Hurricane Creek, with a normal storage capacity of 50.1 acre-feet and a maximum discharge of 232.1 cubic feet per second.
With a low hazard potential and a moderate risk assessment rating, Big Creek-Hurricane Creek H-27 plays a crucial role in managing the risk of floods in the area. Despite its structural height of 31 feet and a spillway width of 34 feet, the dam has not been rated for its condition assessment. It is operated and maintained by local government authorities and has not been subject to state regulation, inspection, or enforcement.
Situated within the Rock Island District and overseen by the Natural Resources Conservation Service, Big Creek-Hurricane Creek H-27 is a vital component of the region's flood control infrastructure. This earth dam, constructed with stone core types and soil foundations, covers a surface area of 3.3 acres and serves a drainage area of 115.2 square miles. While its emergency action plan status and risk management measures remain undisclosed, the dam continues to safeguard the community from potential inundation events.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
