Creating a Catch Bench for a Sliding Bank !

Why Build a Log Wall ?


    Just downstream of the historic Canmore Mines #1, there was a valley slope that consisted of old mine tailings left over from the mining operations. At one location along the creek, the tailings were sliding down into the stream annually and smothering the streambed with coal mine spoil. In order to remediate this problem, BVHD determined that constructing a log wall at the base of the slope, would catch any slippage before it entered the creek. The log wall would need to be approximately 150 feet in length and 2 feet in height. A design was created and the project was completed in 1998.

    The log wall was constructed with peeled spruce and pine logs from a forest wood lot approximately 15 kilometres away. The top of the log wall was planted with indigenous willow cuttings that were pre-rooted before they were planted overhanging the log wall and stream channel.

    This log wall project was a perfect solution to a problem that had been influencing the health of this trout stream for over 70 years. The photos tell the story!

Canmore Creek Rock Wall Project

“Building a Rock Wall to Prevent Bank Erosion!”

A Rock Wall Did the Job!


    It was a difficult task getting all of the rock that was needed down to the bottom of the valley, but we managed to get it there! The objective was to armour the outside of a bend in the stream channel, where fine material was being eroded. By constructing a rock wall with a few rock deflectors repelling the flow in the channel, the project turned out to be a successful one!

    It was rewarding to return to the site in 2008 and see how natural everything appeared and beneath the riparian cover, you could still see some of the large rock that we used to get the job done. (Below: Eric Lardazable and Duncan McColl finish landscaping the site in 1998).

TransAlta Corporation funded these projects on Canmore Creek!

Creating a catch bench at the base of a sliding slope is a great way to prevent fine material from entering the creek!
