Summary

Cole Pond, located in Grand Cane, Louisiana, is a private recreational water source that also serves as a water supply. Built in 1955, this earth dam structure stands at 15 feet in height and spans 785 feet in length, with a maximum storage capacity of 200 acre-feet. The pond covers a surface area of 22 acres and has a drainage area of 2.1 square miles, with a spillway width of 181 feet for uncontrolled water discharge.

Managed by the Louisiana Department of Transportation and Development, the dam is regularly inspected with a low hazard potential and fair condition assessment as of August 2016. With a moderate risk rating, the structure poses minimal risk to its surroundings. The primary purpose of the pond is recreational, attracting water resource and climate enthusiasts seeking a tranquil environment to enjoy outdoor activities. Overall, William J. Cole Pond is a well-maintained water feature that contributes to the local ecosystem while providing a safe and enjoyable recreational space for the community.

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.
