Summary
Owned by the local government, this earth dam was completed in 1979 and primarily serves the purpose of water supply. With a height of 37 feet and a normal storage capacity of 933 acre-feet, the dam spans Troublesome Creek and covers a surface area of 112 acres within a drainage area of 1318 acres.
Managed by the Missouri Dam and Reservoir Safety Program, La Belle Lake Dam has a low hazard potential and is considered to be in satisfactory condition. Inspected last in September 2013, the dam meets state regulations and is regularly monitored for safety. While lacking specific spillway information, the dam's design features a buttress core type on an unlisted/unknown foundation. Situated in Quincy, IL, the dam plays a crucial role in water management for the surrounding area and supports the local ecosystem.
Water resource and climate enthusiasts can appreciate the significance of La Belle Lake Dam as a key component of the region's water supply infrastructure. With its low hazard potential and satisfactory condition, the dam provides essential storage and regulation for Troublesome Creek. As a state-regulated structure, La Belle Lake Dam exemplifies the importance of proper design, maintenance, and oversight in ensuring the safety and efficiency of water resource management systems.

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.
