Summary

This earth dam on TR-Goose Creek stands at a height of 27 feet and spans 660 feet in length, with a storage capacity of 164.2 acre-feet. Its primary purpose is for recreation, providing a serene and picturesque spot for water resource and climate enthusiasts to enjoy.

Although the dam's hazard potential is currently undetermined and its condition is not rated, it is subject to regular inspections with a frequency of one per year. The emergency action plan status, risk assessment, and management measures are all marked as unknown, suggesting a need for further evaluation and preparation. Despite these uncertainties, Woodall Dam continues to offer a valuable recreational resource in the area, attracting visitors with its tranquil surroundings and potential for outdoor activities.

As climate change increasingly impacts water resources, the maintenance and assessment of structures like Woodall Dam become crucial for ensuring safety and sustainability. With its connection to TR-Goose Creek and the Baltimore District, this dam serves as a vital part of the local ecosystem and provides a valuable opportunity for residents and visitors to appreciate the intersection of water management and recreational enjoyment in the face of evolving environmental challenges.

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.
