Summary
Standing at 30 feet high and spanning 357 feet in length, this earth dam holds a storage capacity of 95 acre-feet, with a normal storage level of 65 acre-feet. The dam is situated on the TRIB EAST FORK SHOAL CREEK and falls under the regulatory jurisdiction of the Illinois Department of Natural Resources.
With a significant hazard potential and a moderate risk assessment rating, the dam poses potential threats that require regular inspections and maintenance. The last inspection took place in June 2018, with an inspection frequency of every three years. The dam features an uncontrolled spillway, outlet gates, and a buttress core type, making it essential for water resource management and climate monitoring to ensure the safety and integrity of the structure. For water resource and climate enthusiasts, the Rocky Ford Sportsman Club South Lake Dam provides a recreational haven while also serving as a vital piece of infrastructure that requires careful oversight and management to mitigate potential risks.

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.
