HIGH SOUTH WINDS AND LOW LOW WATER

Because of its long, narrow shape, Lake Winnipeg exhibits a variety of interesting wind and wave effects, including temporary water level rises of up to one metre in height at its southern shore, a process called seiche. This occurs when prevailing northerly winds blow along the length of Lake Winnipeg, exerting a horizontal stress on its surface. Surface waters move in the direction of the wind and pile up along the leeward south shores.  The old times called these "Wind Tides". 
 

Well the last couple of days we have had the opposite effect.  The wind has been blowing hard and consistently from the south leaving Boundary Creek and it's boats high and dry. 
 

 
 
"R Tyme" is sitting on the mud.  And listing badly to port. 
 
 
 
Keith's he said he had to walk up hill on his boat to get to the back door and get off of it, when he left yesterday. 
 
 
"Sommerset's" bow is really high on the mud.
 

 
  
It would be impossible to walk around inside her. 
 

 
 
Sommerset is tipped so high up at the nose that it is forceing her swim platform under the water. 
 
 
 
The outer harbour seems to be fairing a lot better.  Although the water is down, the boats all seem to still be floating. 
 
I'm sure the wind will change back to it's usual North/West and the harbour will fill back up very quickly.
