Summary
The dam, designed by USDA NRCS, serves primarily as a Fish and Wildlife Pond, with additional purposes including recreation. Standing at a height of 23 feet and a length of 735 feet, the dam has a storage capacity of 71 acre-feet and covers a surface area of 7 acres. It is regulated and inspected by the Illinois Department of Natural Resources, ensuring its safety and compliance with state regulations.
The dam's spillway type is uncontrolled, with a width of 20 feet, and it has a low hazard potential. The risk assessment for Gower Pond Dam 1 is moderate (3), highlighting the importance of proper risk management measures. Although the condition assessment is currently not available, the dam's last inspection date was in June 2016. With its role in supporting fish and wildlife habitats and recreational activities, Gower Pond Dam 1 stands as an integral part of the local ecosystem, contributing to water resource management in the area.
Overall, Gower Pond Dam 1 is a significant structure in the Rock Island District, Illinois, serving multiple purposes while maintaining a focus on conservation and recreation. With its modest hazard potential and moderate risk assessment, the dam underscores the importance of proactive risk management and regular inspections to ensure the continued safety and functionality of the structure. As a privately owned entity under state regulation, Gower Pond Dam 1 plays a crucial role in water resource management and climate resilience efforts in the region, contributing to the overall environmental sustainability of the area.

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.
