Water
clarity continued to decline at all stations with Center Lake decreasing to
1.05 meters and North Bay decreasing to 1.4 meters. Water clarity across the whole lake ranged
from a low of 1.0 meters to a high of 1.45 meters. Cyanobacteria numbers continued to increase
at both stations, with 147K at Center Lake and 115K at North Bay. Cyanobacteria was composed of several genera
although Aphanizomenon was dominant.
Dissolved oxygen saturation values were the highest so far recorded this
season at Bantam Lake with all stations (14) having surface saturation values
>130%. This means that phytoplankton
are continuing to grow so water clarity will continue to decline in the days
and weeks ahead, especially if water temperatures continue to remain warm. Cyanobacteria slicks (dense masses of algae
floating on the lake in open water) and scums (dense wind-rows of algae
collecting along the shore) are probably going to be more pronounced especially
along the north shore and worsen in the days and weeks ahead. No anoxic water was found anywhere in the
lake.
