Summary
Completed in 1979, this earth dam with a height of 20 feet and a length of 1050 feet serves as a crucial component for water resource management in the area. With a normal storage capacity of 96 acre-feet and a drainage area of 0.24 square miles, the dam contributes to the conservation and protection of water resources in the region.
Managed by a private entity, Tisons Pond Dam 1 poses a low hazard potential and is currently assessed as "Not Available" in terms of its condition. Despite the lack of detailed inspection data, the dam's primary purpose and design by the USDA NRCS highlight its significance in the local ecosystem and water management infrastructure. With a maximum discharge capacity of 591 cubic feet per second and a spillway width of 80 feet, the dam is equipped to handle potential water flow and contribute to the overall water security in the area.
As a vital structure in the management of Tr- Rector Creek, Tisons Pond Dam 1 serves as a testament to the collaborative efforts of various agencies and designers in ensuring water resource sustainability and environmental conservation. Its completion in 1979 marked a milestone in the region's water management practices, providing essential benefits for fire protection, stock maintenance, and wildlife habitat preservation. With its strategic location and design features, the dam remains a key asset in the broader context of climate resilience and water resource protection in Illinois.

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.
