Summary
Clair, Alabama. Constructed in 1957, this earth dam stands at a structural height of 20 feet with a hydraulic height of 17 feet. The dam has a storage capacity of 50 acre-feet and serves as a popular spot for water recreation activities in the area.
Managed by the Mobile District of the US Army Corps of Engineers, Purvis is a significant water resource with a hazard potential rating of "Significant". While the dam's condition assessment is currently "Not Rated", its emergency action plan status and risk management measures remain unknown. Despite lacking state jurisdiction and regulation, Purvis continues to attract visitors for its recreational purposes, offering a serene environment for fishing, boating, and other water-related activities.
While there are no associated structures or locks, Purvis remains a key feature in the TR Kelly Creek watershed. The dam's maximum discharge capacity is 140 cubic feet per second, ensuring proper water flow management in the area. As a vital part of the local water infrastructure, Purvis stands as a testament to the importance of maintaining and monitoring dams for the safety and enjoyment of all water resource enthusiasts 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.
