North Section – 2007 Weed Survey
On May 31, 2007, we rode
around Hamlin Lake in a pontoon boat attempting to keep weeds to the
starboard and boatable water to the port of the boat.
Using a GPS we recorded the path of the boat.
Then on September 5, 2007, we repeated the process.
Comparing these two routes gives a measure of “boatable”
surface area and where the weed beds are located.
On the map below, the area
between the purple and the shore was where we found weeds already in
place by Memorial Day.
The purple area then represents weed beds that formed between
Memorial Day and Labor Day.
We measured:
This indicates that the
weed beds increased by that much area during the summer of 2007.
