Summary
Completed in 1977, this Earth dam stands at a height of 30 feet and spans 130 feet in length, with a storage capacity of 26 acre-feet. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
With a low hazard potential and a moderate risk assessment rating, Hartsook Pond Dam 1 poses minimal danger to surrounding areas. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge rate of 232 cubic feet per second. Despite its condition assessment being listed as "Not Available," the dam continues to serve its intended purpose effectively and remains a vital resource for the local fish and wildlife population. As a key component of the TR- Nassa Creek NE watershed, this dam plays a crucial role in the overall ecological health of the region.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like Hartsook Pond Dam 1 in maintaining biodiversity and preserving natural habitats. By understanding the design, purpose, and regulatory oversight of such dams, we can work towards sustainable water management practices and ensure the continued protection of our environment for future generations.

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.
