Diversion Gates Finally Closed
August 5th – After the longest continuous use of the Diversion in its history, the Province announced the Diversion gates were closed today. For more than 3 months, the Diversion was responsible for rising Lake Manitoba to its highest level in recorded history. Flowing at times at more than 32,000 cubic feet of water per second(cfs), the Diversion raised Lake Manitoba 5 feet above it’s normal operating range, causing millions in damage and hardship to Manitobans.
Ashton Annouces Work to begin Emergency Channel to reduce Lake Levels to 813.1 by April 2012
Further information on the plans and rational can be found by clicking here. Current plans call to get the Lake level down to 813.1 feet by April 2012, a full foot above maximum operating level, and almost two feet above the level the Lake was at when the Spring Melt began this year. It appears the emergency channel work will NOT result in any additional outflow capacity for the Lake, but rather will permit the Fairford Dam to run at capacity during the Winter months to help with reducing Lake levels. However, there remains a signficant inflow/outflow issue, as the Diversion has an Inflow capacity of approximately 34,000 cfs while the Fairford Dam structure is limited to an approximate 20,000 cfs outflow capacity.
Lake Level Peak Reached
Somewhere around July 25th, Lake Manitoba reached it’s peak level of 817.15 feet. The Province is predicting that with the creation of emergency channels, they will be able to get the Lake down to 813.1 feet by April 2012, putting it a full foot above it’s maximum safe operating range. This would place the Lake a full foot higher than it was in the devastating storm of Fall of 2010.
Mandatory Evacuation of Delta Beach
Due to the disaster, Delta Beach remains under a MANDATORY evacuation affecting approximately 200 residences in the area. All of Delta Beach is under this Evacuation notice. Limited access to the area is available between 8am and 8pm to residents, with a number of restrictions.
The checkpoint is open from 8am to 8pm. Access beyond the checkpoint is available to residents by foot, 1/2 ton or 1 ton trucks, or other high clearance vehicles. Due to debris and unevenness of what remains of the roads, cars and light duty trucks are not recommended. A warning horn is in place to advise of evacuation, and will be sounded three long times to warn of impending flood danger. If you hear the horn, leave immediately.
