Summary

Built in 1975, this dam stands at a structural height of 28.4 feet and has a hydraulic height of 26.2 feet. With a NID storage capacity of 64 acre-feet, Goodwin serves a primary purpose that is not specified in the data provided. The dam has a low hazard potential and a moderate risk assessment rating of 3.

Despite not being regulated or permitted by the state of Tennessee, Goodwin has a history of regular inspections, with the last one conducted in January 2018. The dam does not have an Emergency Action Plan (EAP) prepared, and its condition has not been rated. In terms of risk management measures and emergency preparedness, there is limited information available. The dam does not have any associated structures and does not feature a controlled spillway, but rather an uncontrolled spillway type.

Water resource and climate enthusiasts may find Goodwin's location along Fox Creek to be of interest, given its role in water storage and management in the region. The dam's modest size and low hazard potential make it a relatively low-risk structure, but the lack of a comprehensive risk assessment and emergency preparedness plan may raise concerns. Further data on the dam's purposes, condition assessment, and risk management measures could provide a more comprehensive understanding of its role in the local water infrastructure and its potential impact on the surrounding environment in the face of climate change.

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.
