   Hi All
  </div> 
  <div>
   Yesterday I went for a paddle on Grafton Lake in Keji.
  </div> 
  <div>
   A great day for a paddle it was. Warm with enough wind to discourage the black flies.
  </div> 
  <div>
   Grafton Lake as some of you know was dammed about 100 years ago and then 20 years
  </div> 
  <div>
   ago the dam was removed. This made for an interesting environment as a ribbon of land
  </div> 
  <div>
   was dried around the water. Trees have taken over this ribbon, an interesting mixture of
  </div> 
  <div>
   the trees in the area. Some are now 6 m high. Just a guess. Should be a great area for warblers
  </div> 
  <div>
   but I didn&#39;t poke into it.
  </div> 
  <div>
   An interesting shoal of White Perch was around one of the islands in the lake. hard to estimate
  </div> 
  <div>
   the size maybe 200 m long and thick in spots. Hundreds for sure perhaps in the thousands. I caught
  </div> 
  <div>
   one to verify their id. No doubt has to do with spawning. Several times there was groups chasing
  </div> 
  <div>
   around in circles the same as Gaspereaux.&#160; The size ranged from 15 cms to 40+ cms. Most on
  </div> 
  <div>
   the smaller end of the range. I&#39;ve read of White Perch many times but had never encountered
  </div> 
  <div>
   spawning behavior like this. There was a smaller shoal in another place and many other suitable
  </div> 
  <div>
   spots that I had not gone. A lot of fish for the loons, osprey, otters and terns. A great scene.
  </div> 
  <div>
   There used to be a big population of Tree Swallows at the lake. They were attracted by a mini habitat
  </div> 
  <div>
   created by damming the lake and flooding out mature trees. These trees died as a result and the Swallows
  </div> 
  <div>
   used the stumps for nesting. But time takes its toil, the trees rot and fall down and the water is lowered.
  </div> 
  <div>
   The number of Swallows diminished with the habitat so only a few are left.
  </div> 
  <div>
   However I saw a group of 8 - 10 Cedar Waxwings hawking insects out over the water. There is a few
  </div> 
  <div>
   snipe at the old coffer dam. and a pair of Canada Geese in the marsh.
  </div> 
  <div>
   Not a place often paddled but interesting nevertheless.
  </div> 
  <div>
   Enjoy your spring paddles.
  </div>
