Summary
Built in 1939 with a height of 12 feet, this dam serves the primary purpose of water supply, providing a storage capacity of 51 acre-feet. Situated on the TR Thomson River offstream, it covers a surface area of 8 acres and has a drainage area of 5 square miles. Despite its age, the dam is deemed to have low hazard potential and its condition is currently not rated.
Managed by the Rock Island District of the US Army Corps of Engineers, Mononame 574 has not undergone recent inspection or assessment for emergency preparedness. While it does not fall under state jurisdiction or regulation, it remains a crucial infrastructure for water resource management in the region. The dam's location and purpose make it a significant component of the local water supply infrastructure, contributing to the overall water management efforts in Grundy County.
As a key element in the water supply network, Mononame 574 plays a vital role in ensuring water availability and security for the residents of Trenton and surrounding areas. Its historical significance, combined with its functional importance, underscores the need for continued monitoring and maintenance to uphold its integrity and safeguard against potential risks. As water resource and climate enthusiasts, understanding and advocating for the upkeep of such structures is essential to ensure sustainable water management practices in the face of changing environmental conditions.

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.
