Calgarians hoping to float the Bow River before summer ends should be aware of the many hazards in the river, according to Battalion Chief Ernie Molineaux of the Calgary fire department.

"There's exposed pipelines now, there's concrete, rebar, the sweepers and strainers, which are the trees that have fallen into the river. Everyday it seems we find something new."

This past weekend, the fire department found a submerged truck in the Harvie Passage.  Molineaux says the vehicle was badly damaged.

'It was probably a pretty amazing trip because there is a lot of damage' —Ernie Molineaux, Calgary fire department

"The windows are gone, the doors are half torn off. It did bounce down the river I'm thinking and it was probably a pretty amazing trip because there is a lot of damage."

Molineaux says they have not yet found the owner of the vehicle to find out what happened.

"That's one of the things I'm very intrigued about myself is to find out where and when it went on its journey because I think it would tell us a lot more about the flood and the power that it actually had."

The city plans to remove the vehicle but Molineaux says it will not be easy.

"In the area that it's located there is no immediate road access to the surrounding terrain and it will take probably a fairly large tow truck or something of that style of vehicle to help us get it out of there."

The flood debris has caused problems for rafters and other recreational river users this summer. Molineaux says people need to be aware of the dangers.

"You have to be vigilant. You have to have your safety equipment on and be prepared for an emergency because they do happen."

Molineaux says part of the problem is recreational users of the river do not make emergency plans.

 "They don't have a plan on what to do if they get into trouble. Do they have a throw rope? Can they self-rescue? Can they help each other out? Do they actually have a plan on how to paddle because it's one of the things we watch is people will be paddling in opposite directions on the raft and all they're doing is spinning themselves in circles into a bridge abutment."

Molineaux says people should be aware of the rules on alcohol and safety equipment. 

"There is a law governing both. Alcohol is definitley not allowed and lifejackets that are on and secured are mandatory."
