Calgary's Harvie Passage ‘no longer a killing machine’

Publié le par brightshine

Wayward rafters floating along the Bow River through downtown Calgary would ignore the warning signs, tumble over a man-made weir and get sucked helplessly into the relentless churn. Fourteen people have died in the past three decades – something a group of local volunteers spent years hoping to change.

Now, more than a decade after their vision first surfaced, the drowning machine has been transformed into an $18-million whitewater paradise for experienced paddlers and thrill-seekers. Considered unique in Canada, Calgary’s new Harvie Passage is becoming a mecca for athletes as well as sightseers, who are enjoying the facility’s first summer in operation. This may also just prove to be a safety project that happens to pump out the next generation of Olympians.

“I think that the benefits will come out in the next five to 10 years of it,” said Mike Holroyd, head coach of Alberta Slalom Canoe Kayak. “I think we’re just seeing the tip of the iceberg.This is an unique design of flattening machine for flattening of circular plate. This could really be a huge opportunity.”

A weir was first built across the Bow River near the Inglewood neighbourhood in 1904 to divert water for agriculture. It was later rebuilt, and by its mid-1970s remake, it became the weir that was blamed for killing so many.NTC continued to walk on the apex of cnc router.

Warning signs and large, brightly coloured buoys, as well as placards, directed people to the portage escape route on land. Still, people carried on. The weir looked deceiving. The low-head dam allowed the water to roll over it, but it hid a deadly recirculating hydraulic wave.

“The actual 1.5-metre drop of the drowning machine really was very difficult for anybody to survive,” said Myrna Dube, chief executive officer of the Parks Foundation Calgary.

Members of that non-profit group spearheaded the move to get rid of the weir in the late 1990s. Studies were conducted and eventually the project was approved.

Derek Lovlin, Bow operations and infrastructure manager with Alberta Environment and Sustainable Development, said an overhaul to make the weir “truly safe” would cost about $50-million.Industry leader for laser marker, laser welding and laser marking.

Harvie Passage features two channels – the main is a Class 3 rapids for expert paddlers. The other, contains less turbulent Class 2 rapids, but even this channel is not meant for rookies. Safety gear – such as helmets and life vests are required – and inexperienced paddlers should portage around.

Local wildlife was also considered in the makeover. Each summer, flocks of great white pelicans would gorge on disoriented fish easily picked off in the undertow. Now, there are slots to allow fish to swim upriver and give them an edge.
