Spray River water breach threatens trout population
Generator fails, water breaches spillway
By Cathy Ellis, For The Calgary Herald July 29, 2011
The cutthroat trout population in the Spray River could be wiped out due to dirty and unnaturally high water flows, in part the result of mechanical problems at a TransAlta hydroelectric facility near Canmore.
"Fish have evolved genetically for spring runoff, but as the (high stream flow) persists into mid-and late summer, this becomes an unnatural occurrence which fish are less able to tolerate," said Bill Hunt, resource conservation manager for Banff National Park.
"Obviously, the longer this goes on, the worse those odds are."
