Summary

Completed in 1965, this dam stands at a height of 57 feet and has a storage capacity of 528 acre-feet. The dam spans 613 feet in length and is designed as a buttress type structure.

Regulated by the Illinois Department of Natural Resources, Santa Fe Lake Dam has a significant hazard potential and is subject to regular inspections with a frequency of 3 years. The dam features an uncontrolled spillway with a width of 18 feet and outlet gates that are also uncontrolled. In the event of an emergency, the dam's Emergency Action Plan status and contact information are not available.

While Santa Fe Lake Dam has a moderate risk assessment rating, its risk management measures and condition assessment details are not currently available. The dam's location on TRIB HALLOCK CREEK, its association with offstream CHILLIOOTHE0OFFSTREAM city, and its proximity to the Rock Island District highlight its importance in water resource management and climate resilience efforts in the region.

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. 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

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, 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.
