About this dam

Ipava Settling Basin Dam

Located in Fulton, Illinois, the Ipava Settling Basin Dam serves as a crucial water resource management structure along the Francis Creek. Built in 1978 by AMAX COAL CO., this private-owned Earth dam stands at a height of 24 feet and spans 480 feet in length, with a storage capacity of 478 acre-feet. Despite its uncontrolled spillway and outlet gates, the dam's hazard potential is classified as low, making it a stable and essential component of the local water infrastructure.

Managed by the Illinois Department of Natural Resources (IDNR), the Ipava Settling Basin Dam presents a moderate risk assessment level, indicating a need for continued monitoring and maintenance. The dam's primary purpose is listed as "Other," suggesting a multifunctional role in water resource management. With state-regulated permitting, inspection, and enforcement in place, the dam operates under strict guidelines to ensure the safety and integrity of its structure, as well as the surrounding environment.

For water resource and climate enthusiasts, the Ipava Settling Basin Dam offers a fascinating case study in dam engineering and management. From its unique design features to its low hazard potential and moderate risk assessment, this Earth dam provides valuable insights into the complexities of maintaining water infrastructure in a dynamic natural environment. As a pivotal structure along the Francis Creek, the dam plays a crucial role in flood control, water storage, and environmental protection, highlighting the intricate interplay between human intervention and natural systems in water resource management.

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.

FAQ

About Ipava Settling Basin Dam

Where does the data for Ipava Settling Basin Dam 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.
