Summary
Built in 1950 for fire protection, stock, or small fish pond purposes, this dam has a hydraulic height of 17 feet and a structural height of 20 feet. It stands along the TR RAMAR CREEK and has a storage capacity of 210 acre-feet, with a normal storage level of 153 acre-feet. Despite its age, the dam is considered to have a low hazard potential and its condition is currently not rated.
Managed by the US Army Corps of Engineers' Mobile District, Underwood No 1 serves as a crucial resource for water supply and wildlife habitat in the region. The dam has a length of 590 feet and can discharge a maximum of 644 cubic feet per second. While it has not undergone recent inspections and its emergency action plan status is unknown, the dam continues to support local fire protection needs and ecological diversity in the area.
Underwood No 1's historical significance and functional importance make it a valuable asset in water resource management and climate adaptation efforts. As climate change impacts become more pronounced, maintaining and monitoring dams like Underwood No 1 will be essential to ensure water security and ecosystem resilience in the face of evolving environmental challenges.

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.
