Summary
This earth dam with a buttress core type serves the purpose of water storage, with a maximum capacity of 235 acre-feet. The dam is situated on the Meramec River watershed with a drainage area of 575 square miles, providing essential water resources for the surrounding area.
With a surface area of 16 acres, the dam poses a high hazard potential due to its uncontrolled spillway type and lack of inspection and enforcement measures. While the condition assessment is listed as "Not Rated," the risk assessment indicates a moderate level of risk. Despite being privately owned, Bridgewater Lake Dam falls under the jurisdiction of the state of Missouri, with no federal regulations or permitting in place.
Water resource and climate enthusiasts can appreciate Bridgewater Lake Dam's role in water storage and management within the region. The dam's location on the Meramec River watershed highlights its importance in regulating water flow and providing essential resources for both human consumption and ecological balance. However, the high hazard potential and lack of regulatory oversight underscore the need for proactive risk management measures to ensure the safety and sustainability of this vital infrastructure in the face of changing environmental conditions.

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.
