Forest Hills Lake Dam Reservoir Report
Nearby: Lake Diamond Dam Pinewild Lake Dam
Last Updated: March 4, 2026
Forest Hills Lake Dam, located in Chain of Rocks, Missouri, is a privately owned structure primarily used for recreation purposes.
Summary
This earth dam stands at a height of 25 feet and has a storage capacity of 120 acre-feet, with a normal storage level of 75 acre-feet. The dam overlooks the TR-McCoy Creek and covers a surface area of 9 acres within a drainage area of 65 acres.
Despite being a low hazard potential structure, Forest Hills Lake Dam has not been rated for its condition assessment. With no state regulation, inspection, or enforcement in place, the dam's maintenance and safety are left in the hands of its private owner. As water resource and climate enthusiasts, the unique design elements of this buttress core dam, situated in St. Charles County, Missouri, present an intriguing case study for understanding the importance of proper dam management and safety protocols in recreational settings.

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.
