September 8, 2015 - The 2015 MN DNR State Fair polling results are now published.  Question #9 pertains to Aquatic Invasive Species:

February 5, 2014 - Lake George in New York has implemented a new program to prevent the spread of Aquatic Invasive Species. Lake George is about half the size of Lake Winnibigoshish and twice the size of Otter Tail Lake. FULL ARTICLE

September 17, 2013 - Minnesota Public Radio's Dan Gunderson reports on AIS in Minnesota.  Some feel the Department of Natural Resources is hampering locals from doing what they feel is necessary to protect public waters from the spread of Aquatic Invasive Species (AIS).  Others indicate public monies need to be available to protect public waters.

August 15, 2013 - READ ARTICLE: "How Many More Lakes will we Lose?"  writes Joe Shneider; Chair of the Coaltion of Minnehaha Creek Waters, a nonprofist organization of 13 lake, creek, and homeowner associations in the Minneapolis area.  There mission is to preserve, protect and improve the Minnehaha Creek Watershed and surrounding area waters from aquatic invasive species and storm water runoff.

May 26, 2013 - Non-Native Species Invade Lake Erie -  .....Unlike some of the other issues facing the lake, the one of invasive species seems to be the hardest to predict and most difficult to manage. One can regulate the frequency and amount of wastewater discharge. Reduce phosphorus run-off by changing agricultural practices. Stop beach littering by changing attitudes. Stemming the tide of invasive species is a tougher nut to crack. READ THE FULL ARTICLE

May 25, 2013 - ‘What are lakes worth?’ - Public concern and awareness have dramatically increased the last couple of years as invasive species such as zebra mussels have infested more Minnesota lakes. As a result, local funding to fight aquatic invasive species has increased by 40 percent over the past three years, with watershed districts, park districts, cities, counties and other local governments spending more than $5 million on it. “The interest in this issue is rising each year,” said Jeff Forester, executive director of the Minnesota Lakes and Rivers Advocates. “It will have devastating effects for everyone even if you don’t use the lakes.” Losing water and fishing quality could put a dent in the state’s $11-billion-a-year tourism industry, which relies heavily on resorts. “What are the lakes worth to Minnesota?” said Barb Halbakken Fischburg, president of the Lake Detroiters Association. “They support industry and jobs and tourism.” READ THE FULL STORY.....

May 2, 2013 - A zebra mussel scare has halted work on the new bridge over the St. Croix River. Six of eight barges hauled by truck from Wisconsin and slated to be floated in the river this week were found to contain dead zebra mussels, according to the Minnesota Department of Natural Resources. The DNR is investigating the incident, which could lead to misdemeanor charges of transporting invasive species for the state contractor building the new St. Croix bridge.

May 1, 2013 - Prevent invasive mussels from infesting Okanagan Lake - D.D. Davis - Lake Mead Instructor

Boat inspection trainer D.D. Davis of Lake Mead, Nevada holds a collection of the quagga mussels that have invaded the lake, incased in clear plastic at her talk on control of invasive aquatic species Tuesday. By Judie Steeves - Kelowna Capital News - Halfway measures will get halfway results, warns D.D. Davis, boat inspection trainer in the Lake Mead National Recreation Area in Nevada—and once invasive quagga mussels are in your lake, they’re there forever.

So, she advocates taking severe measures upfront to prevent an infestation, in order to avoid billions of dollars in damage to everything aquatic, from the valley’s ecology to waterworks, bridges, boats and beaches.

Davis was one of the speakers at an Aquatic Invasive Species Workshop held in Kelowna Tuesday by the Invasive Species Council of B.C.

In her neck of the woods, and in many other western U.S. states, there are mandatory inspections of boats before they can leave or enter a different waterway, in an effort to prevent the spread of both zebra and quagga mussels, invasive species that have already forever altered the Great Lakes.

Davis told those attending the workshop a new fish hatchery on Lake Mead had to be shut down because it couldn’t continue to operate under the infestation of quagga mussels.

As well, the mussels have gotten into the penstocks and they clog pipes, screens, gates and other equipment at the Hoover, Davis and Parker Dams, she reported, costing millions a year.

A ‘Don’t Move a Mussel’ campaign is underway  there, while other states run similar campaigns to alert boaters and all other water users of the danger of transferring anything from a wakeboard or fishing rod to a boat or scuba gear from one body of water to another without a thorough cleaning and appropriate treatment.

Because the Lake Mead area is a half day drive for 30 million people, it’s a busy recreation area, and a popular place for those who enjoy water sports, Davis noted.

Compliance with regulations regarding movement of boats is expensive so boaters are not likely to voluntarily comply, she warned, and commercial marinas don’t want to annoy customers, so they can’t be relied upon to ensure compliance, she added.

De-contamination equipment can cost a quarter million dollars, and it will sit idle without enforcement, she said.

All weekend boaters are asked to Clean, Drain and Dry every surface of their boats and equipment, including bilges in order to stop aquatic hitchhikers.

The veligers, or microscopic larval stage can last for 27 days in standing water, so protocols to get rid of them are essential before leaving a contaminated water so they are not moved to infest new waters.

She advised B.C. to be proactive; to have a strategy ready, to focus on early detection and to learn from other jurisdictions where they already have the invasive mussels and have been trying to control them.

Consistency in messaging and ways of dealing with the problem would help water users to comply with recommendations regarding control and preventing their spread, she said.

Boat inspections where boaters are asked where their boat was last and how long it’s been out of the water are needed, she said.

She was impressed with the beginning this province has made to pass stringent legislation to prevent the movement of such invasive aliens, and to launch an information campaign to alert people to the dangers of their spread.

The good news is, Davis says she’s confident the valley can prevent contamination with the mussel with adequate effort.

This provincial government passed new legislation last December amending the Controlled Alien Species Regulation to prevent shipping or transport of a single mussel—alive or dead.

Offenders face a penalty of $100,000 or a year in prison, or both.

The Conservation Officer Service plans to set up checkpoints in areas such as Osoyoos and Golden to check boats this summer and try to prevent contaminated boats from entering B.C., said Gail Wallin, organizer of the conference and executive-director of the ISCBC.

They are working with marinas across the province to inform boaters about the mussels and will mount a multi-pronged campaign to spread the Clean, Drain and Dry message, but she says they’re now working on getting the attention of people like wakeboarders who can transport the veligers in the ballast of their boards; and snowbirds who took their boats to southern spots like Lake Mead during the winter months and are now bringing them home to put into Okanagan Lake.

Federal legislation is needed so that inspections could take place at the border, to ensure only decontaminated boats are permitted into Western Canada, but the difficulty is, they’re already in Eastern Canada, so regulations would have to be drafted that only applied to the West.
