Summary
Built in 1953 by the USDA NRCS, this earth dam stands at a height of 30 feet and stretches 400 feet in length, with a storage capacity of 26 acre-feet. Its primary purpose is for irrigation, but it also serves for recreation and other uses.
Managed by the Illinois Department of Natural Resources, Nugent-Shapanski 2 is regulated, inspected, and permitted by the state agency. Despite its age, the dam's hazard potential is labeled as "undetermined" with a condition assessment of "not available." The last inspection was conducted in 2013, with no specific risk assessment or emergency action plan in place. With a spillway width of 10 feet and a maximum discharge capacity of 85 cubic feet per second, this dam plays a crucial role in water resource management in the region.
Overall, Nugent-Shapanski 2 represents a significant piece of infrastructure in the Kansas City District, providing essential water storage for irrigation purposes in Jersey County, Illinois. Its historical significance, combined with its state-regulated status, highlights the importance of proper maintenance and monitoring to ensure the safety and efficiency of this vital water resource structure.

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.
