Ghost Reservoir to be used for flood protection

TransAlta and the provincial government have reached an agreement to use the Ghost Reserviorwest of Calgary for flood mitigation.

• Ghost Dam changes could help prevent flooding, says city
• $100M Alberta dam upgrades will help flood control, says province

TransAltahas agreed to hold the reservoir at its minimum level until July 31 six weeks longer than usual.

"By keeping the reservoir levels low, it means that we'll have additional capacity to contain a little bit more water should the circumstances reproduce as last year," saidTransAltaspokeswoman StaceyHatcher.

The province estimates this would reduce peak flows along the Bow River by 100 cubic metres per second. That would be on top of the reduction of 400 cubic metres per second that TransAltaprovided by other upstream reservoirs during the 2013 floods.

"Since then, we've been working with communities to strengthen our communications and prepare better. Today's agreement is just one more step in that process," said Dawn Farrel,TransAlta'spresident and CEO, in a written statement.

Ward 7 Coun. Druh Farrell said the agreement is good news.

"A lot of people were worried that they weren't coming to the table and negotiating. And so it appears that it's been effective. For this year anyway," she said.

The government said Wednesday theagreement is for this year only.

Both parties will evaluate how well it worked after July 31 to determine if it should be a long-term deal.
