Alberta's booming economy and rapid growth have made it the province most vulnerable to looming water shortages, he said.
Climate change will also exacerbate any droughts, the research indicated. Glaciers are dwindling and the annual accumulation of snow is lower. Both supply water to Prairie rivers.
Schindler co-authored the study with U of A researcher Bill Donahue. It was published Monday in an early online edition of the Proceedings of the National Academy of Sciences.
Their study indicates that water levels in the rivers of Alberta have declined 20 to 84 per cent in the last 100 years. Waterways in central and southern Alberta have seen the biggest declines.

“ Environmental Impacts<br />
<br />
Tar sands development has a direct impact on local and planetary ecosystems. In Alberta, this form of oil extraction completely destroys the boreal forest, the bogs, the rivers as well as the natural landscape. The mining industry believes that the boreal forest will eventually colonize the reclaimed lands, yet 30 years after the opening of the first open pit mine near Fort McMurray, Alberta, no land is considered by the Alberta Government as having been "restored."<br />
<br />
Furthermore, for every barrel of synthetic oil produced in Alberta, more than 80 kg of greenhouse gases are released into the atmosphere and between 3 and 5 barrels of waste water are dumped into tailing ponds. The forecast growth in synthetic oil production in Alberta also threatens Canada's international commitments. In ratifying the Kyoto Protocol, Canada agreed to reduce, by 2012, its greenhouse gas emissions by 6% with respect to the reference year (1990). In 2002, Canada's total greenhouse gas emissions had increased by 24% since 1990”<br />

Plus I recall reading were oil production uses water to fill the cavities crated by oil extraction <br />

The only good is knowledge...
Population in the rural areas is declining but the need for water is increasing. Corporate farms, feedlots and mass crop production is on the rise. Like any corporation, profits rely on production. Profits must exceed the previous year at any cost.

Expect little from life and get more from it.
That still don't explain why the water levels south of Fort McMurray are getting low. The creek I played by as a child, is a mere trickle now in comparison to then. "Flat Lake" is now a farmers field and the Athabasca river was never it's source. Perhaps Schindler never lived in the area. No doubt the tarsands & the pulpmill have an impact but I still maintain that the water levels were going down prior to the full scale operations. The pulpmill is only ten or so years old and considered one of the largest anywhere.

Considering we didn't have a flake of snow from October to February, one has to wonder if it's oil (which is a major user of fresh water) that's lowering the rivers or a lack of precipitation.
Southern Alberta experienced record rainfalls and floods last summer, but in the same period, central and northern Alberta saw not a drop.

The story also doesn't mention the new water treatment plant in Edmonton that removes the water from sewage (the biosolids are removed for fertilizer and methane production) and the water re-processed for use in industrial and oilfield use, and for golf courses.
