Summary
Built in 1959 by designer E.T. Archer, this Earth-type dam stands at a height of 43 feet and stretches 1350 feet in length. Its primary purpose is for recreation, with additional use for water supply. The dam holds a storage capacity of 1775 acre-feet and covers a surface area of 106 acres, serving a drainage area of 658 square miles.
Managed by the Dam and Reservoir Safety Program in Missouri, Brookfield Dam is regulated, inspected, and enforced by the state. Its spillway type is uncontrolled, with a width of 100 feet. Despite being classified as having a high hazard potential, the dam's condition is deemed satisfactory as of the last assessment in 2007. With a moderate risk level assigned, the dam is subject to regular inspections every two years to ensure safety measures are in place.
Brookfield Dam remains a vital structure in the region, providing both recreational opportunities and water supply for the surrounding area. Its presence on TR West Yellow Creek adds to the natural beauty of the landscape while also serving as a crucial component of the local infrastructure. Enthusiasts of water resources and climate will appreciate the detailed information on the dam's design, purpose, and regulatory oversight, highlighting its importance in maintaining both safety and sustainability in the community.

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.
