Summary
With a height of 25 feet and a storage capacity of 80 acre-feet, the dam serves the surrounding area by providing a reliable water source for these essential needs. Situated along the TR-Big Creek river/stream, the dam covers a surface area of 6 acres with a drainage area of 152 acres.
Although the dam's hazard potential is rated as low, it is important to note that its condition has not been formally assessed to date. Despite this, the dam continues to play a crucial role in the community, supporting recreational activities and maintaining water levels for various uses. The dam's location within Carroll County highlights its significance in the region, with Congressman Sam Graves representing the area.
The Rock Island District of the US Army Corps of Engineers oversees Harts Lake Dam, ensuring its safe operation and compliance with regulatory standards. While the dam does not currently have a designated emergency action plan or risk assessment in place, its low hazard potential suggests a minimal risk to surrounding areas. As water resource and climate enthusiasts, it is important to monitor and support the responsible management of dams like Harts Lake to protect water resources and maintain ecological balance in our communities.

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.
