Summary
Built in 1945, this dam stands at a structural height of 28 feet and has a hydraulic height of 25.5 feet, providing a maximum storage capacity of 94 acre-feet. Despite its age, the dam is in satisfactory condition and is inspected annually by the Tennessee Safe Dams Program to ensure its safety and regulatory compliance.
With a high hazard potential due to its location and design, Pioneer #2 poses a moderate risk, as indicated by a risk assessment rating of 3. Although the dam does not feature an outlet gate or a controlled spillway, its uncontrolled spillway design helps manage excess water during periods of high flow. The dam's satisfactory condition and regular inspections contribute to its overall reliability in protecting the surrounding area from potential flooding events.
The surrounding community in Dyer, Tennessee, can rest assured knowing that Pioneer #2 is being closely monitored and maintained to prevent any risk of failure. With its historical significance and vital role in water resource management along the Forked Deer River, this dam stands as a testament to the importance of infrastructure maintenance in mitigating climate-related challenges and ensuring the safety of both people and property in the region.

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.
