Summary
Constructed in 1971, this earth-filled dam stands at a height of 29 feet and spans a length of 490 feet, providing a storage capacity of 131 acre-feet. Located in the Lone Trees Corners area, the dam regulates water flow in the tributary of Crow Creek, contributing to the overall ecosystem health of the region.
Managed by the Illinois Department of Natural Resources, the Newton-Hager Lake Dam has a low hazard potential and a moderate risk assessment rating. Despite its age, the dam's condition assessment is not available, indicating a need for further evaluation to ensure its structural integrity and safety. With a spillway width of 80 feet and uncontrolled outlets, the dam operates effectively to manage water levels and maintain the surrounding environment.
As a significant feature in the Rock Island District, the Newton-Hager Lake Dam offers a picturesque setting for outdoor enthusiasts and climate advocates to appreciate the intersection of water resources and conservation efforts. With its strategic location and vital role in water management, this dam serves as a reminder of the importance of sustainable practices in safeguarding our natural resources for future generations.

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.
