Summary
This dam, with a height of 30 feet and a length of 300 feet, serves a primary purpose that is categorized as 'Other'. It has a storage capacity of 72 acre-feet and a normal storage level of 50 acre-feet, covering a surface area of 5 acres and draining an area of 0.16 square miles.
The dam, regulated by IDNR and situated on TR- ADAMS CREEK W, has an undetermined hazard potential and an inspection frequency of 0. The spillway is uncontrolled with a width of 15 feet, while the outlet gates are also uncontrolled. This structure, part of the St. Louis District, does not have any associated locks and has a moderate risk assessment rating of 3. Despite its condition assessment being unavailable, the dam has not been determined to pose an immediate threat.
Water resource and climate enthusiasts interested in the maintenance and regulation of dams will find Whitfield Pond Dam 3 to be a structure of significance. Its historical completion date, design details, and current risk assessment provide valuable insights into the management of water resources in Illinois. As a privately owned dam with state jurisdiction, its role in flood control and water storage within the region of Macoupin Station makes it an essential component of the local water infrastructure.

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.
