Summary
Completed in 1986, this earth dam stands at a height of 41 feet and stretches 340 feet in length, serving primarily for recreational purposes. With a normal storage capacity of 56 acre-feet and a maximum storage of 72 acre-feet, Seebrook Dam is situated along the TR Charrette Creek, within the St. Louis District of the US Army Corps of Engineers.
This dam, regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, poses a high hazard potential due to its location and structure. However, it has been assessed as satisfactory in condition, with the last inspection conducted in February 2017. Despite its moderate risk assessment, Seebrook Dam has not had any emergency action plans (EAP) prepared or updated recently, raising concerns about its readiness for potential emergencies. With a drainage area of 32 square miles and a surface area of 4 acres, the dam has a maximum discharge capacity of 156 cubic feet per second.
For water resource and climate enthusiasts, Seebrook Dam offers a fascinating case study in private dam ownership and the management of recreational water resources. With its unique design and location along the TR Charrette Creek, this dam serves as a vital asset for the surrounding community of Innsbrook. However, ongoing monitoring and maintenance efforts are crucial to ensure the safety and sustainability of this structure in the face of changing environmental conditions and potential hazards.

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.
