Zebra Mussels (ND Game & Fish)

JAMESTOWN, N.D. (Prairie News Service) – Compared with other states, North Dakota has yet to see a big invasion of aquatic nuisance species. But officials are not letting their guard down, and to protect regional lakes, they ask boaters to pitch in with key cleaning steps.
The North Dakota Game and Fish Department says because of its location, North Dakota has largely been shielded from nonnative plants, insects and other organisms infesting its waterways as they have in coastal areas and the Great Lakes region.
Ben Holen, the department’s aquatic nuisance species or ANS coordinator, said the southeastern part of the state has seen activity, namely with zebra mussels.
“Zebra mussels, they’re manipulators of the ecosystem. They completely cover docks,” he explained. “They clog water intakes. They push nutrients to the bottom, which increases vegetation growth out there.”
That’s bad news for native species, as well as economic activity from water recreation. As North Dakotans prepare their boats for the summer, they’re asked to memorize key steps for each outing. Those include cleaning, draining and drying all equipment after every use, with a focus on removing all plants or animals from the watercraft prior to leaving the site. Doing so means these tiny creatures won’t find their way to the next lake.
While his department does its mitigation work, Holen said, boat owners are being given tools to aid in their responsibility. Each year, boat-cleaning stations are being set up at access points to various North Dakota lakes.
“We’ve been looking to provide more and more each year for boaters, so it’s never been easier for boaters to get cleaned, drained, dry at the boating access,” he continued.
Holen said if boaters are not eager to help out, they could feel an economic pinch later through tax increases and higher water bills if state and local agencies have to clean or replace infrastructure damaged by an infestation.
