Summary
This structure, situated on the TRIB BLUFF DITCH, serves as a crucial water resource management tool in the area. With a dam height of 44 feet and a length of 240 feet, the dam has a storage capacity of 49 acre-feet, providing vital water storage for irrigation and flood control purposes.
Managed by the Illinois Department of Natural Resources, the dam is subject to state regulation, inspection, and enforcement. Despite being classified as having a low hazard potential, it is considered to have a moderate risk level. The dam features an uncontrolled spillway, outlet gates, and buttress core design. Although the condition assessment is not available, the dam is inspected every five years to ensure its structural integrity and functionality.
With a primary purpose of "Other," Coal and Crane Creek Structure 15 plays a significant role in water management and conservation efforts in the region. Its association with the Natural Resources Conservation Service highlights the importance of sustainable practices in maintaining and enhancing water resources. As climate change impacts water availability and quality, structures like Coal and Crane Creek Structure 15 become vital components in ensuring resilience and adaptation to changing environmental conditions.

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.
