Stop zebra mussels, protect Candlewood Lake

Volunteers inspect every out-of-town boat for signs of invasive species, delaying scourge for now

Stop zebra mussels, protect Candlewood Lake

It may be that zebra mussels will show up in Candlewood Lake some day, but a handful of people are trying hard to put that awful event off for as long as possible.

Volunteers are examining every boat that enters the lake from out of town, setting up watch at the boat launches and eyeballing each hull.

If any evidence of zebra mussels is found, the volunteers take down the boater, cuff his wrists and ankles, and burn his boat right there on the ramp.

Just kidding! That is what I would advise them to do, but they are much more civilized.

In fact, the Connecticut Department of Environmental Protection designed the Volunteer Invasive Investigator Program to “help educate people on ways to keep our waters clean and prevent the spread of aquatic hitchhikers into the lakes and rivers of Connecticut.”

The Investigators check for signs of invasive species, collect information about where the boats have been, and what cleaning steps the boat owner took before venturing near Candlewood Lake.

The DEP looks for volunteers with good communication skills, willingness to work weekend and holiday hours and a “sincere interest in lake protection.”

Catrina Morgan is one of those volunteers.

She is a senior biology major at Western Connecticut State University. Last year, she worked on a project with the university and the Candlewood Lake Authority to study an invasive plant called Eurasion water milfoil, the weed that clogs shoreline waters all around the lake.

Morgan grew up in Newtown, which is not a lake community, but some of her friends lived on the lake and she says she always had an affinity for Candlewood.

She started at Western as a nursing major but soon found she liked the idea of “being outside and working on the world’s health instead of an individual’s health.”

She switched to biology, and is planning to pursue a master’s in an ecology-related field after graduation and an eventual career in some kind of nature-based job, possibly with a focus on invasive species and finding ways to stop them without chemicals.

“I’d rather find the natural balance,” Morgan said.

Zebra mussels have been found in lakes Zoar and Lillinonah, which are dammed portions of the Housatonic River. Water from the Housatonic is pumped into Candlewood during times of low power use. The lake’s owner, FirstLight Power Resources, then allows water to flow from Candlewood through a generator when more power is needed. Although the pumps from the river to the lake have screens, they are not fine enough to prevent zebra mussel larvae from entering.

But the most common method of zebra mussel infestation, apparently, is via boats that have been transported from mussel-laden waters. That is what Morgan and her fellow volunteers are trying to stop.

“I think the best way to prevent the spread of mussels is educational outreach,” Morgan said. “It would benefit everyone if we can keep them out of the lake.”

She spent part of the Memorial Day weekend at the Danbury boat launch, inspecting every boat. On Saturday, she worked at the Lattin’s Cove launch from 8 a.m. to noon.

If you are as good a person as Catrina Morgan, you can become an Invasive Investigator, too.

The next training will take place on June 18 at the New Fairfield Community Room on Route 37 from 9:30 a.m. to about noon.

DEP staff will teach you how to recognize local invasive species along with how to conduct a voluntary inspection and to collect data.
