Ashlu Creek is a short and swift river-like creek in British Columbia. It is a tributary of the Squamish River and enters it about 24.3 km northwest of Squamish. Course Ashlu Creek, often called the "Ashlu River" (due to its size) or "the Ashlu", begins at the outlet of an unnamed lake east of Mount Crerar. From there all the way to its mouth, it flows southeast. Starting at Ashlu Falls is 3.9 km long Ashlu Canyon has several big rapids and large drops making it one of the best kayaking locations in the area. It ends about 2.1 km above the river's mouth. Hydroelectricity A 49 megawatt run-of-river hydro installation below the canyon went online December 2009. A diversion weir 5 km above the power house feeds water down a bored tunnel to the site. It is owned by Innergex Renewable Energy and is expected to produce 265,000 MWh annually. Tributaries Ashlu Creek's only major tributary is Tatlow Creek, which flows northeast from remote Tatlow Lake and joins the Ashlu about 15.8 km below its source. It does have several much smaller tributaries though: Shortcut Creek Snafu Creek Endell Creek Red Mountain Creek Pykett Creek Coin Creek Stuyvesedt Creek Roaring Creek Pokosha Creek Rob Creek Cassetta Creek Mowitch Creek Sigurd Creek See also List of British Columbia rivers References Sea-to-Sky Corridor Rivers of the Pacific Ranges Canyons and gorges of British Columbia New Westminster Land District
