….Climate change, natural sedimentation and pollution from rampant development of the Alberta oilsands play a role in the changing delta and another factor is post-glacial rebound — the slow lifting of the lake bottom after the end of the ice age.

Also, the Peace and Athabasca rivers flow into the delta and, as oilsands development surges ahead industry withdrawals from the Athabasca River are increasing, with current figures hovering around 111.5 million cubic metres of water annually.

But dams on the Peace River remain in the crosshairs as the major culprit and fears are growing about what will happen when Site C, the third dam on the Peace River, is built.

These concerns don’t seem to sink in for provincial and federal governments considering projects such as Site C or the massive Teck Frontier oilsands mine proposed for 30 kilometres south of Wood Buffalo Park, said Melody Lepine, government and industry relations director for Mikisew Cree First Nation.
