Summary
Completed in 1961, this earth dam stands at a height of 31 feet and stretches 363 feet in length, with a storage capacity of 25 acre-feet. Situated on the TR-ILL River W, this structure plays a crucial role in mitigating flood risks in the area with a low hazard potential, as it is regulated, inspected, and enforced by the IDNR.
The Hambaugh-Martin WS Str 8 dam not only serves flood risk reduction but also supports fire protection, stock, or small fish ponds in the region. With a drainage area of 0.08 square miles and a maximum discharge capacity of 182 cubic feet per second, this structure provides essential water resource management in Meredosia. Although its condition assessment is currently not available, the dam's moderate risk level suggests the need for ongoing risk management measures to ensure its continued functionality and safety for the surrounding community.
In the event of emergencies, the structure's emergency action plan (EAP) status and risk assessment readiness remain unclear. However, with a history of periodic inspections and a regulated state jurisdiction, the Hambaugh-Martin WS Str 8 dam stands as a critical infrastructure for water resource and climate enthusiasts to monitor and support in safeguarding against potential flood risks and ensuring sustainable water management in the region.

Dam Data Reference
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.
