Summary

Built in 1960, this earth dam stands at a height of 19 feet, with a hydraulic height of 18 feet and a length of 475 feet. The dam has a storage capacity of 58 acre-feet and a maximum discharge of 85 cubic feet per second, making it suitable for recreational activities like fishing and boating on the TR-Flat Branch river or stream.

Despite its low hazard potential, Knight Lake Dam has not been rated for its condition assessment. However, it serves as a key water resource in Elmore County, Alabama. The dam has not been modified over the years and does not have any associated structures or outlet gates. While the dam's emergency action plan status is unknown, it is essential for water resource and climate enthusiasts to monitor its condition and ensure that it continues to provide safe and enjoyable recreational opportunities for the community.

As a vital part of the local water infrastructure, Knight Lake Dam contributes to the conservation and management of water resources in the area. Its strategic location, close to Congressional District 02, Alabama, and under the jurisdiction of the Mobile District, highlights its importance in the region. With its recreational purposes and historical significance dating back to the 1960s, the dam serves as a valuable asset for water enthusiasts and climate advocates alike, emphasizing the need for sustainable management practices to maintain its functionality for future generations.

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.
