The South Thompson River has finally receded enough to allow boats to navigate its length.

Nearly a month ago, high water led the RCMP to ban watercraft from the river.

A police assessment on Wednesday determined boats can now safely pass under the CN Rail trestle and the Red Bridge.

But rainfall predicted for the Shuswap drainage basin over the next few days could raise water levels to make the area below the CN trestle once again impassable.

“There could be the potential for another closure. We hope not,” said RCMP Staff Sgt. Grant Learned.

The last of the closed areas between the Red Bridge and the confluence can now be accessed by watercraft.

RCMP officers patrolling the South Thompson River on Wednesday decided water levels under the CN Train trestle at Riverside Park had receded enough for typical boats to safely pass underneath.

Those piloting watercraft that ride high or have towing towers or antennae are asked to be extremely careful when passing through the area.

“They have to be very, very aware that while the waterway is open through there, their craft might not be suitable,” said Learned.

All the Gabion baskets have now been removed but fencing remains. Popular beach areas along Riverside Park will become accessible again on Saturday, according to a City news release.

And the swimming area is closed until further notice with strong currents and floating debris causing hazardous conditions.

The Thompson Drive boat launch is also closed until further notice after suffering water-damaged.

The Pioneer Park and McArthur Island boat launches are open to the public.
