Summary
Constructed in 2006 by the USDA NRCS, this private-owned Earth dam serves the primary purpose of grade stabilization, with a dam height of 30 feet and a maximum storage capacity of 25.4 acre-feet. The dam's low hazard potential and moderate risk assessment highlight its crucial role in mitigating flooding and protecting the surrounding area.
With a spillway type of "Uncontrolled" and uncontrolled outlet gates, Adams Dam ensures effective water management and regulation in the event of heavy rainfall or high discharge rates. Despite being not rated for its condition assessment, the dam's structural integrity and design by the Natural Resources Conservation Service uphold its reliability in safeguarding the local community and environment. The dam's proximity to Brashear and its strategic location in the St. Louis District underscore its significance in the broader water resource infrastructure of Missouri.
As an essential component in the conservation and management of TR-Floyd Creek's watershed, Adams Dam plays a vital role in maintaining the ecological balance and hydrological stability of the region. The dam's association with the St. Louis District and its primary source agency being the state of Missouri reflect a collaborative effort in water resource management, emphasizing the importance of public-private partnerships in safeguarding water resources and adapting to the challenges of climate change. For water resource and climate enthusiasts, Adams Dam stands as a symbol of resilience and innovation in sustainable water management practices.

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.
