Flood Bulletin #17

• Yesterday, ice jams along the Assiniboine River between Poplar Point and Baie St. Paul Bridge caused surges in the water levels and overtopped and breached the dikes in some areas.  Dike repairs and reinforcements were being made by crews as the ice slowly moved along the river and a secondary dike was quickly constructed in one area.  Water rose and then fell by close to six feet in some areas as the ice moved through.  Two families were voluntarily evacuated.  There has been no damage to homes in the area.  The dikes at the nearby Hutterite colony were overtopped in a few places, but there was no significant damage.  The ice jams have now moved out of the area and water levels are dropping.
• Approximately 35 people and 25 pieces of heavy equipment worked to repair and reinforce the dikes and address any dike breaches caused as the ice jam moved through.  Crews are continuing to work on the dikes today, they are being patrolled on a 24-hour basis by 16 staff and equipment is staying on-site in case it is needed.  The dikes protect local farms in the area and the La Salle River watershed.  The dikes, originally built in 1912 and reinforced in 1950 and 1997, were again reinforced early this spring.  Without this reinforcement, the overtopping due to ice jamming would have been much more serious and difficult to contain.
• The release of this ice jam is expected to cause a rise of one ft. in Winnipeg along the Assiniboine River as it moves east towards Winnipeg. 
• The Town of Melita has declared a state of local emergency.  Work is ongoing on the Melita dike to protect the community.
• Large flood tubes and gravel are being put in place around the Ashern area to protect against overland flooding.  So far, no homes have been affected.
• Overland flooding is affecting Fisher Branch and flood-tube barriers are set up.  Larger flood-tube barriers are also being delivered this morning.
• Overland flooding has also resulted in the evacuation of an additional three families from the RM of Ritchot because of a lack of safe road access.
• A section of the west side of the ring dike at St-Lazare will be raised by approximately one ft. as a precautionary measure in preparation for high flows from the Qu’Appelle River expected later this week.  A second peak is expected over the weekend along the Qu’Appelle River, which feeds into the Assiniboine River.  Part of PTH 41 is expected to close because of high waters.
• The sandbag machine in Brandon has been requested by the Town of Hartney and the machine is being relocated there today.  Hartney is sandbagging because to assist with flood protection at a nearby Hutterite colony.
