Summary
Built in 1958 for recreational purposes, the dam stands at a height of 20 feet with a hydraulic height of 16 feet. It has a storage capacity of 140 acre-feet, with a maximum discharge of 170 cubic feet per second. Despite its low hazard potential, the dam's condition has not been rated, and its emergency action plan and risk assessment measures are not currently in place.
This dam, managed by the Mobile District of the US Army Corps of Engineers, serves as a vital water resource for the community, providing not only recreational opportunities but also crucial storage capacity for water management. The surrounding area benefits from the reservoir's normal storage of 80 acre-feet, contributing to the overall water supply in Calhoun County, Alabama. With its strategic location and purpose, Mccullars No 1 plays a significant role in the local water infrastructure and climate resilience efforts.
As water resource and climate enthusiasts, understanding the importance and functionality of structures like Mccullars No 1 is essential for promoting sustainable water management practices and ensuring the safety and reliability of our water systems. With the dam's history dating back to the late 1950s, ongoing monitoring and assessment are crucial to maintaining its integrity and effectiveness in the face of changing environmental conditions. By staying informed and engaged in the management of water resources like Mccullars No 1, we can work towards a more resilient and sustainable future for our communities.

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.
