ALMS passes resolution to ask Province to provide proactive Wave Protection whenever Diversion is run during flooding events 

ALMS Executive on July 19th passed a unanimous resolution asking the Province to take proactive action to protect communities whenever the Diverision is operated.

Wave damage is one of the most damaging impacts of Large Lake flooding. In both 2011 and 2014 flooding, wave damage was particularly devasting. Wave protection such as GeoTubes has been found to prevent such damage.

A copy of the resolution is contained below:

WHEREAS the majority of damage caused to Lake Manitoba communities was a result of wave action and wind tide;

AND WHEREAS our communities ability to defend against such damage has been eroded by the flood of 2011 and years of the Lake being artificially high by the combined use of the Portage Diversion and the Fairford Dam;

AND WHEREAS the use of GeoTubes has been proven to provide protection against wave damage during times where Lake Manitoba is at flood stage;

THEREFORE BE IT RESOLVED the Association of Lake Manitoba Stakeholders resolves to call upon the Province of Manitoba to amend the regulations regarding the operation of the Portage Diversion to require the erection of Wave Protection for communities around Lake Manitoba when the operation of the Diversion is expected to, or will contribute to, causing the Lake level to exceed 812.5 feet above sea level.
