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 funds will allow Arlington and Alexandria to create new wetland areas near the stream, thus adding needed habitat, enhancing aesthetics and improving water quality.

“This federal grant will help us fund the crucial first phase of the comprehensive restoration of Four Mile Run,” Arlington County Board Chairman Christopher Zimmerman said in a statement. “Restoration of the wetland and stream banks in tidal Four Mile Run, which we expect to begin work on next year, is central to the effort to return the stream to a more natural, better functioning waterway that will serve people from across the region.

The Ballston Beaver Pond, as it’s called, was initially designed to collect stormwater runoff from I-66. But that started to change in the 1990s when beavers moved in and dammed up the drainage system, creating a pond and wetlands to form. The Beaver Pond is now a habitat frequented by muskrat, geese, ducks, heron, egrets, redwing blackbirds, fish, turtles and the occasional beaver.

The Beaver Pond is located next to a bike trail that connects Ballston and the Custis Trail, just north of the ramp from Fairfax Drive to I-66.

With all this talk of blizzards and groundhogs seeing their shadows, now might be a good time to willfully escape from reality and dream about spring (which is exactly a month and a half away.) Tonight, naturalist Greg Zell will lead a presentation about the wide variety of natural habitats and unique wildlife that reside within Arlington’s borders. Imagine, while everybody else is fighting for bread, milk and toilet paper at the grocery store, you can be learning about natural wonders that exist in your own backyard.
