Summary

Built in 1970 by the USDA NRCS, the dam stands at a hydraulic height of 20 feet and a structural height of 22 feet, with a length of 300 feet. The reservoir created by the dam has a storage capacity of 61 acre-feet and covers a surface area of 1.4 acres.

Despite its low hazard potential, the dam has a moderate risk assessment rating of 3. It is not currently regulated or inspected by the state, but it serves as an important recreational and water supply resource for the surrounding area. With a maximum discharge of 237 cubic feet per second, the dam plays a crucial role in managing water resources in the region, particularly in times of high water flow.

T A Smith Lake Dam, situated on Terre Rouge Creek, is a vital structure for maintaining water supply and supporting recreational activities in the area. While it may have moderate risks associated with it, the dam continues to serve its intended purposes effectively. As a point of interest for water resource and climate enthusiasts, this dam exemplifies the importance of infrastructure in managing water resources and adapting to changing environmental conditions.

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.
