More Updates -

Winnipeg flood response eased but ice jams still greatest threat:
The Floodway continues to flow smoothly and a major ice jam dislodged Friday -resulting in a few hundred volunteers being sent home as flood threat eased. The area is not entirely past all risk of flooding due to the presence of ice in the floodway, which is not meant to be opened in the presence of major ice flows. At least one large ice pan is still in the floodway - this has the risk of causing another ice jam and flooding.

Areas at the greatest risk of flooding, are north of Winnipeg , concentrated for now in Selkirk, although there has been some flooding to the south as well. At the Manitoba U.S border area Highway 75 has been closed for a few days and should remain so for another week or so. It is also difficult to say what the impact will be of the water diverted through the Floodway on ice jams to the north. Because ice is flowing through the Floodway, when it exits the northern outlet, all the ice will then meet existing ice jams near Selkirk and other communities if they have not dislodged by then.

The outlook is that flooding will still come - the slow moving Red River crest is in the Emerson to Letellier area and is expected at Morris on Monday. It should reach the south end of Winnipeg on Thursday. Warmer temperatures expected Sunday and Monday will also speed the spring thaw and increase local surface runoff into the river basin.

North Dakota , the Fargo area, is seeing a second major crest in the Red River . Though not as severe as the end of March when many were evacuated, threats to dikes are severe and flooding is taking place in several areas. Manitoba residents will also have to be on the lookout for this second wave of elevated river levels as it moves north into the region again.

There are no plans to send out our Toronto team of volunteers yet as the situation is being handled well by local volunteers. I'll continue posting the updates both here at the Canada News blog as well as the MissionLog over on Wordpress.com and will post volunteer opportunities for Toronto area folks wishing to get involved at the Project417 website - project417.com -
