Summary
As a private-owned dam with a primary purpose of a Fish and Wildlife Pond, it stands at a height of 26 feet and has a length of 430 feet, creating a surface area of 8 acres and a maximum storage capacity of 171 acre-feet. The dam is situated on TR-LOTT'S CREEK and is under the jurisdiction of the Rock Island District of the US Army Corps of Engineers.
Despite its low hazard potential and moderate risk assessment rating, Cottrel Lake Dam has not been rated for its condition assessment, and no emergency action plan (EAP) has been prepared or updated. The dam features an uncontrolled spillway with a width of 22 feet and lacks outlet gates for controlled water release. While it has not undergone recent inspections or maintenance, the dam continues to provide essential environmental and recreational benefits to the local community.
Water resource and climate enthusiasts can appreciate the unique role that Cottrel Lake Dam plays in supporting fish and wildlife habitats, stabilizing grades, and offering recreational opportunities in the area. Its peaceful setting and connection to TR-LOTT'S CREEK make it a valuable asset for conservation efforts and outdoor enjoyment, highlighting the importance of responsible dam management and maintenance to ensure its continued functionality and safety for generations to come.

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.
