Summary
Built in 1995 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a hydraulic height of 27 feet. With a storage capacity of 145 acre-feet and a drainage area of 169.98 square miles, the dam serves the primary purpose of flood risk reduction in the area.
The dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite not being regulated or inspected by the state, the structure has a moderate risk assessment rating of 3. The spillway type is uncontrolled, with a width of 30 feet, and there are no outlet gates associated with the dam. Overall, Big Creek-Hurricane Creek T- 23 plays a crucial role in managing flood risks in the region and is a significant asset for water resource and climate enthusiasts to study and appreciate.
As part of the Rock Island District, the dam is not managed by the US Army Corps of Engineers and does not have a designated Emergency Action Plan in place. While there are no associated structures or locks, the dam's design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water resource management. With its strategic location and purposeful design, Big Creek-Hurricane Creek T- 23 stands as a testament to the importance of proactive flood mitigation measures in safeguarding communities and ecosystems against the impacts of extreme weather 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.
