Greg McCullough, a University of Manitoba researcher who studies satellite images of surface algae slick, said the algae bloom on Lake Winnipeg appeared to be getting progressively worse. In September 2005, McCullough said the bloom was 50 per cent larger than the satellite images he'd studied for the previous 20 years -- a trend echoed in this summer's algae slick as well. You see the worst blooms in the hottest summers," he said, explaining algae grows faster in bright sunshine. "Last year, it was also a very wet year... the increased flow (into Lake Winnipeg) brought in more nutrients, so the lake was super-charged with nutrients. Everything was adding up to be a very bad year for blooms.
You can't walk on the shore, along the edge of the water, without stepping on them," said Wilderness Committee local director Eric Reder, who described a "clumpy and fibrous" algae bloom on Meditation Lake. The Wilderness Committee is unhappy with logging in the Whiteshell and believes loggers are taking far more trees than necessary. While the group wonders whether there's a link between logging and lake contamination that could have led to the unusual die-off, Reder said it's impossible to prove.
The province has also requested that nitrates, which are produced as a result of ammonia removal, be removed as well. The scientists are explicit in stating that nitrate nitrogen is not necessary for the blue-green (BG) algae to bloom -- only phosphorus is. The BG blooms are typically seen in August in Lake Winnipeg and in Lake of the Woods. The BG can obtain all the nitrogen they need from the atmosphere in a matter of weeks. In Lake Erie, a rigorous phosphorus removal strategy implemented 20 years ago stopped such blooms. Today the water is clear. No nitrate removal was implemented. We need to rigorously remove phosphorus from all discharges at all times. Winnipeg's total cost burden would decrease significantly if stringent ammonia nitrogen removal was required in the summer/fall mon...
The rest of the world has known about this forever and have become blase," [David Bird] said at a pre-convention information meeting Sunday. "It's a world situation, there are problem areas everywhere," he said, pointing to Lake Okeechobee in Florida which is permanently covered with a thick coat of algae and the Baltic Sea which has a bloom of blue-green algae thousands of metres wide. "The other things that can lead to blue-green algae are overforestation and improperly maintained septic systems," [Marie-Andree Fallu] said. "We had some extreme weather in 2005 and 2006, so what we're seeing in terms of algae in 2007 is kind of like a hangover.

It smells worse than being inside a pig barn," the Killarney resident said. "If you go for a walk around the lake, it's just a horrific, rancid smell ...and now with the heat, who knows what's going to happen? "Why (algae blooms) happen one year and not the next we can't answer that, but certainly Killarney Lake has chronic (algae) problems," [Wendy Ralley] said. "What makes one year worse than the other depends on the local conditions that present themselves that year." "The town is going to have to analyze exactly all the things they did this year because they've had blue-greens before, but never to this extent. These are recreational beaches that people go to enjoy," [Bill Paton] said. "It happens every year, but the extent of it is a shocking thing to happen. If these small towns ...
