Bel Air's Bynum Run Pond is bright green, but not with envy

Bel Air's Bynum Run Pond, long popular with both humans and large geese, has been looking a little brighter than usual.

In fact, it's bright green.

The culprit is actually Harford County's own doing, along with the help of some robust algae.

The county has been treating the pond with AquaShade, a pond dye and treatment designed to screen sunlight so it minimizes algae growth, explained Paul Magness, chief of capital planning and development for the county's parks and recreation department.

"It's Gatorade, is what it kind of reminds you of," Magness said with a laugh about the pond's new color.

The treatment is a mix of blue and yellow dyes, he said. That, combined with a healthy dose of goose "activity," has been turning heads from passers-by along Route 22.

Although all of the county's dozen or so ponds get the treatment, Bynum is perhaps the most visible, Magness said.

"Bynum is probably the greenest, and part of that is because of the number of geese," Magness said. "We have geese that are basically resident geese there."

With roughly 200 geese regularly hanging out at Bynum Pond and being fed by visitors despite the signs against it, there is not much the county can do, Magness said.

Also, the pond is fairly shallow, which means it heats up very quickly, promoting the algae growth, he said.

"The health of the pond would probably be better if we had fewer geese there, but there's frankly not much we can do," he said.

The pond was treated on April 24 and June 5, and will get another round in another month or so.

That means residents can expect to see a very green Bynum Run Pond for at least a little while longer.
