Delta Beach Association Website

20140630-181227-65547497.jpgEnvironment Canada has issued a wind warning for Lake Manitoba. Current forecasts shows sustained wind from the Northwest at 37 km/h increasing to 56 km/h by Tuesday morning with gusts to 74 km/h. Winds expected to diminish to 37 km/h by Tuesday night.

Note: Sustained winds of 60 km/h will generally create a wind tide of 3 feet plus wave height of 3 feet.

At current lake levels estimated at 814 feet asl, this means wave and wind tide can combine for a height of 820 feet asl.20140630-180850-65330530.jpg

Lake Manitoba Emergency Alert Issued

This is a Manitoba Emergency Alert issued by Manitoba Emergency Measures Organization

The Manitoba Hydrologic Forecasting Centre has issued a moderate to moderately high Wind Warning for June 12 for the south Lake Manitoba areas. Wind speed and direction could raise levels by as much as two to three feet on the southeast shore and one to two feet on the south shore.

Flood Response won’t help: Dr Forbes : Emergency Channel won’t help Lake Manitoba flooding situation

Dr Scott Forbes has provided an analysis and commentary on the Province’s recent announcement of their intention to reopen the Lake St Martin emergency channel:

The Province of Manitoba has announced that it has applied to the Federal Government to open the ‘emergency channel’ from Lake St. Martin to address flooding on Lake Manitoba and Lake St. Martin. A Free Press article today (11 June) indicated that the purpose of opening the channel was ‘to lower a rising Lake Manitoba.’

For Lake Manitobans, this action by the Selinger government is the rough equivalent of going to the doctor and receiving a sugar pill to deal with a broken leg: it is a placebo, nothing more.

The primary value is political, to allow water stewards to appear to be doing something when in fact they have not yet addressed the underlying problem: the outflow from Lake Manitoba is too small to cope with the extra and artificial inflow from the Portage Diversion.

Opening the emergency channel this summer will have no effect on the level of Lake Manitoba before winter. Zero. None. Nil. Nothing.

The emergency channel exits from Lake St. Martin and lowers the level of that lake. It will be useful there, as the water level on Lake St. Martin this summer is high. However, given that the residents of Lake St. Martin have yet to return home more than three years after they were evacuated, it will also have little effect on them.

The emergency channel allows more water to be drained out of Lake Manitoba over winter without flooding Lake St. Martin. Normally flows out of Lake Manitoba are reduced to prevent the buildup of frazil ice on the Dauphin River that exits Lake St. Martin. Frazil ice reduces outflow from that lake.

The primary value of the emergency channel to Lake Manitobans is to allow us to clean up faster after a flood – not to prevent flooding in the first place.</blockquote

Share Your Views on the

Lake Manitoba and Lake St. Martin Outlet Channels Conceptual Design Study

Manitoba Infrastructure and Transportation is conducting a conceptual-level study for the Assiniboine River and Lake Manitoba watersheds to determine how future flood risks can be mitigated. Part of this study is to identify and evaluate options for enhanced Lake Manitoba and Lake St. Martin outlet capacity,

A public open house has been organized to provide information on the options that are being studied, and to provide you with an opportunity to provide input and your views on this subject. The open house will provide information about:

  • study scope and objectives
  • preliminary outlet options for Lake Manitoba and Lake St. Martin
  • screening-level designs and cost estimates for these options
  • effectiveness and impacts of the outlet options

The public open house will be held at:

Centennial Hall
Ashern, Manitoba
June 18 2014, 5:00 p.m.-8:00 p.m.
