Summary
Completed in 1947, this earth dam stands at a height of 16 feet and stretches for 2000 feet, providing a storage capacity of 190 acre-feet. The dam overlooks the Wattensaw Bayou, contributing to the irrigation needs of the region.
Despite its low hazard potential and a current "Not Rated" condition assessment, the dam has not undergone recent inspections or assessments. The lack of state regulation, permitting, and inspection raises concerns about the safety and maintenance of this essential water resource infrastructure. With a surface area of 19.9 acres and a drainage area of 0.18 square miles, Mccallie-North Lake Dam plays a significant role in managing water resources in the area.
As water resource and climate enthusiasts, it is crucial to monitor the condition and management of structures like Mccallie-North Lake Dam to ensure the safety and sustainability of our water systems. With its primary purpose being irrigation, the dam remains a vital asset for agricultural activities in the region. Efforts must be made to prioritize inspections, risk assessments, and maintenance to safeguard this valuable water resource infrastructure for the future.

Dam Data Reference
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.
