How can Randall Pond be used as an effective flood control tool when it appears to be at maximum capacity all the time?

Although the pond water level appears to remain at the top of the concrete outlet structure, the pond is not at maximum capacity, says city of Wilmington project engineer Robert Gordon.

“There is a smaller, two-foot deep weir in the center of the larger, 120-foot long weir that restricts the outflow from the pond and provides a downstream flood control benefit,” Gordon explains.

He said Randall Pond is approximately 25 acres in size, or 30 acres if the islands in its center are included.

“A pond of this size can store a very large volume of stormwater without causing a substantial rise in water level or increase in outflow.  The 120-foot long concrete weir is designed to safely pass the flows from the larger storms that enter the pond,” Gordon says.

All new development remains subject to the city’s comprehensive stormwater management ordinance and most projects are required to provide on-site flood control measures, Gordon adds.

“The Randall Pond was intended to supplement these on-site measures as well as provide flood control for older adjacent neighborhoods that do not have flood control measures in place,” he says.
