Watercraft banned from Clear Lake this summer to halt zebra mussels By: Carol Sanders Posted: 7:15 PM CDT Thursday, May. 9, 2024 Last Modified: 8:58 PM CDT Thursday, May. 9, 2024 Updates

The federal government will close Clear Lake to all watercraft this summer in an effort to stop the spread of zebra mussels in southwestern Manitoba.

“Zebra mussels present a real and significant threat to the waters of Riding Mountain National Park and all areas downstream,” said federal Environment Minister Steven Guilbeault in a news release Thursday. “The temporary watercraft management measures in place for Clear Lake in 2024 will provide the best opportunity for Parks Canada and partners to fully assess the situation and protect ecological integrity for future generations.”

Effective immediately, motorized boats, canoes, kayaks, and paddleboards are barred from Clear Lake, which is 90 kilometres north of Brandon. Swimming and angling are still permitted.

Manitoba Natural Resources Minister Jamie Moses held a news conference late Thursday to confirm the lake will remain open to swimmers and encouraged Manitobans to enjoy the water, boardwalk and beach this weekend.

“We’re excited that the federal government is willing to at least have things like beach toys on the lake — that the lake will be open for swimming,” Moses told reporters from his office. “I think that comes from some of our advocacy work on behalf of Manitobans.”

Moses said he’s been working to get Guilbeault and Parks Canada to consider other options and to consult more with those impacted at Clear Lake. The provincial minister said he was in Clear Lake two weeks ago to meet with those who’d be affected the most, including businesses at the townsite of Wasagaming and the local chamber of commerce.

“I think what we want is to have a very balanced approach — one that sees opportunities for Manitobans to have access to the lake — to be able to use the lake and ensure there are economic activities like tourism at Clear Lake,” said Moses. A “balanced approach” would take the local economic interests into consideration as well as the long-term health and sustainability of the lake, he said.

“I think we could find the balance if there was further consultation with the government but sadly we haven’t seen that.”

There are three exemptions to the no watercraft rule: commercial tour boat the Martese, a vessel from Keeseekoowenin Ojibway First Nation for cultural use, and boats used by Parks Canada for emergency or research needs.

Keeseekoowenin Chief Dwayne Blackbird said he supported the efforts to “give the lake a break” this summer.

“We want our great-great grandchildren to enjoy a clean and healthy Clear Lake,” Blackbird said in a statement.

Zebra mussels were discovered by Parks Canada officials in Clear Lake in November. It said an infestation of the invasive species that can spread by attaching itself to boats could cause irreversible ecological damage to the lake and downstream bodies of water.

While water testing over the winter did not turn up any zebra mussel environmental DNA, Parks Canada had said more research and scientific evidence was needed before a decision on closing the lake was made.

Wasagaming averages 300,000 visitors a season, has hundreds of private cabins, a full-service campground, golf course and restaurants, hotels and businesses catering to the swell of tourists.

Winnipeg Liberal Terry Duguid, the federal government’s special adviser on water, said there’s “no question” it’s the right decision to protect the lake and surrounding bodies of water.

“I understand local businesses’ worries… but at the end of the day… the consequences of it could be devastating,” he said. “This is what the science and the evidence show to protect the lake.”

Duguid said the government expects the last water sample to be taken in mid-July, though testing could take longer if the deepest part of the lake isn’t within the testing temperature window, which must be between 10 C and 12 C.

If no evidence of zebra mussels or larvae is found in samples, Park’s Canada could reopen the lake to boaters, said Duguid, who doesn’t believe the decision will affect reservations for the park’s campground.

Duguid said Parks Canada will issue financial support to tourism operators, but details have yet to be determined.

Moses wouldn’t say if he was disappointed by the decision, instead saying: “What we’ve supported from the start is having a clear communication process on this plan. What we heard from the start is there wasn’t enough consultation from the federal government and Parks Canada.”

He said the province has advocated for Ottawa to support impacted businesses.

“I think we’re going to see some financial package being put out by the federal government,” said Moses. The province is not planning to top up any federal support for local businesses that take a hit from the watercraft ban, he said.

The government is instead beefing up funding to fight invasive species like zebra mussels with $500,000 — a 40 per cent budget increase, the minister said.

It means more washing stations and decontamination stations in Manitoba, some of which will be operational this weekend with parks in the province set to open.

“We’re doing our part as a province,” Moses said. “I encourage Manitobans to do their part as well, to make sure that they clean, drain and dry all watercraft as they enter and exit water bodies in Manitoba — to make sure we’re doing our part to prevent zebra mussels from spreading in Manitoba.”

Riding Mountain Tory MLA Greg Nesbitt criticized the move, saying it will devastate the local economy, which generates a year’s worth of income in just a few months.

He questioned whether temporary financial support is sustainable.

“How long can you keep subsidizing local businesses who are only open during the summer?” he said. “My overriding concern is if they close (the lake), will they ever open it again?”

Nesbitt questioned the move as other lakes in Manitoba have zebra mussel infestations without being closed.

“Once a lake gets zebra mussels, its pretty hard to eradicate them… you just have to work with what you have, decontaminate boats,” he said.

He proposed continued water testing and more watercraft inspections in lieu of closing the lake.
