Summary
This privately owned earth dam stands at a height of 30 feet and has a storage capacity of 48 acre-feet. Situated on the TR-Missouri River, the dam serves to protect the surrounding area from debris and enhance recreational opportunities for the community.
Despite its low hazard potential, Parsons Lake Dam has not been rated for its condition assessment. The dam's design features a buttress core type and an unlisted/unknown foundation. While it does not fall under state jurisdiction or regulation, the dam's maintenance and safety remain a priority for its private owner. The dam's location in Warren County, Missouri, makes it an essential structure for water resource and climate enthusiasts interested in the region's hydrological management.
The Parsons Lake Dam's significance lies in its role in debris control and recreational activities along the TR-Missouri River. With a storage capacity of 48 acre-feet and a surface area of 3 acres, the dam contributes to the local ecosystem's stability and provides a valuable resource for the community. While its condition assessment remains unknown, the dam's historical completion date and ongoing operational status make it a point of interest for water resource enthusiasts looking to understand the region's infrastructure and environmental management efforts.

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.
