Coal And Crane Creek Structure 1 dam
Coal And Crane Creek Structure 1
Coal and Crane Creek Structure 1, located in Schuyler, Illinois, is a privately owned earth dam designed by USDA NRCS and completed in 1971. The dam, standing at 40 feet tall and 500 feet long, serves as a crucial water management infrastructure for the TRIB COAL CREEK DITCH. The primary purpose of this structure is listed as "Other," with a low hazard potential and a moderate risk assessment rating.
Managed by the Illinois Department of Natural Resources, Coal and Crane Creek Structure 1 is state regulated, permitted, inspected, and enforced. The dam features an uncontrolled spillway, outlet gates, and a buttress core type. With a storage capacity of 150 acre-feet and a normal storage level of 70 acre-feet, this dam plays a vital role in flood control and water resource management in the region. Despite its age, the condition assessment of the dam is currently listed as "Not Available," with the last inspection conducted in September 2020.
For water resource and climate enthusiasts, Coal and Crane Creek Structure 1 presents an intriguing case study of a privately owned earth dam that continues to provide essential water management functions in Illinois. With its design by USDA NRCS and state regulation by IDNR, this structure showcases the collaboration between different agencies to ensure the safety and efficiency of water infrastructure. The detailed data on the dam's specifications, regulatory status, and risk assessment rating offer valuable insights into the challenges and importance of maintaining such critical infrastructure in the face of changing climate conditions.
Dam data reference
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 Coal And Crane Creek Structure 1
Where does the data for Coal And Crane Creek Structure 1 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.
