Summary
Constructed in 2004, this earth dam with a buttress core type reaches a height of 35.5 feet and spans 300 feet in length. With a storage capacity of 29 acre-feet and a normal storage level of 24 acre-feet, this dam serves a crucial role in managing water resources for the surrounding area.
Despite its low hazard potential, Brown's Dam #3 is subject to regular state inspections and enforcement, ensuring its structural integrity and safety. While it is not currently rated for condition assessment, the dam's last inspection in November 2011 indicated a satisfactory state. The dam's location in Rock Port, Missouri, within the jurisdiction of the DAM AND RESERVOIR SAFETY PROG, highlights the importance of state oversight in safeguarding water resources and mitigating potential risks associated with dams.
In the hands of a private owner, Brown's Dam #3 plays a vital role in water management and flood control within the region. As climate change continues to impact water resources, the presence of well-maintained dams like Brown's Dam #3 is crucial for ensuring the resilience and sustainability of water infrastructure in Missouri. With state regulation, regular inspections, and a commitment to safety, Brown's Dam #3 stands as a model for responsible water resource management 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.
