Ballston Pond, the wetlands created by beavers between I-66 and Fairfax Drive, will be drained completely in order to restore the pond.

The pond has already begun draining after Arlington’s Dept. of Environmental Services removed the stop logs on the pond’s weir, after which the county will begin the construction bidding and plant treatments.

Construction to the “new and improved pond design that will provide stormwater treatment benefits, as well as improved habitat for wildlife,” is expected to begin in spring 2014, according to Arlington Stormwater Outreach Specialist Jen McDonnell.

The pond will be drained to encourage the wildlife to find new homes during the construction. When construction is complete, stop logs will be placed back in a new weir, and the pond will refill naturally from Lubber Run, McDonnell said. The pond will still receive water flow from Lubber Run until the construction begins.

“Draining the pond will not have any long-term impact on the animal habitat,” McDonnell wrote in an email. “The construction and subsequent addition of native plants will result in a ‘new’ pond that will provide a better variety of wildlife habitats and improved stormwater treatment.”
