River users told to be careful around Tolmie slide

Undercutting erosion from spring runoff is bringing down chunks of the Tolmie slide on the Chilliwack River.
"It's a dynamic river. It's been doing that for many years," said Dave Lamson, president of the Chilliwack River Action Committee. "But it means it's more dangerous now.
"People have to know that they have to be more careful."
The river has been fairly high due to the runoff for the past three weeks, but it's starting to recede now, he said.
Charlie Hilliard with Kids in the Nest Educational Society has trained her river cam on the slide, and is worried about the safety of kayakers and rafters coming down the river.
She uploaded up a five-minute video on Youtube called "Danger Tolmie Slide June 24/09" that clearly shows debris coming down.
"The kayakers are oblivious to the dangers as they come down," she said.
Hilliard has been watching chunks of mud and trees splashing into the water since mid-June, including a very large tree now wedged in the water near the bottom of the slide.
"It's a lot worse now," she said on Wednesday. "The public needs to know is should stop kayaking along the slide area."
Hilliard, who is also an avid kayaker herself, said she wants more signs put up to warn river users.
Lamson said they are already two signs up as it is, near the parking lot at Obyrne Road, and on the riverside near private property. He said he's not sure if more signage can be put upstream of the slide.
"Actually the Anderson slide is sloughing even more," said the CRAC official. "That's our major concern now."
CRAC is a group of volunteers that has applied for and been granted thousands in funding over the years to install protective groynes at several clay slide sites along the river. The groynes, which are large boulders, protect the "toe" of the slide from being eaten away by erosion.
In terms of Tolmie, he said the 21 protective boulders that went in were doing a good job at the upstream end. A slump on the downstream side also covered some of the groynes. But there isn't adequate funding in place yet to complete the terracing needed to make the slide area even more stable, Lamson added.
