Summary

Completed in 2020, the earth dam stands at a height of 21 feet, with a hydraulic height of 18 feet and a total structural height of 25 feet. The dam has a storage capacity of 95.8 acre-feet, with a normal storage level of 72.8 acre-feet and a surface area of 7.5 acres.

Situated on TR-Mills Creek, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. With a moderate risk level of 3, the dam does not fall under the jurisdiction of any state regulatory agency and is not subject to regular inspections or enforcement measures. Despite its uncontrolled spillway type, the dam has a maximum discharge capacity of 168 cubic feet per second, serving as a vital structure for both water resource management and recreational opportunities in the area.

Overall, Brown Lake # 1 Dam serves as a crucial component of the local landscape, providing essential storage capacity for water resources while offering a wide range of recreational activities for enthusiasts to enjoy. Its completion in 2020 underscores its modern design and functionality, ensuring its continued contribution to the community's well-being and environmental sustainability.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
