Water
clarity at both Center Lake declined to 1.25 meters while North Bay decreased
to 1.65 meters. Water clarity decreased across the whole lake uniformly, with
values ranging from a low of 1.25 meters to high of 1.8 meters. Cyanobacteria cell numbers increased at both
stations to levels over 100K with Aphanizomenon dominant. Slicks (dense masses of algae floating on the
lake in open water) were noted in the center of the lake and towards South Bay,
scums (dense wind-rows of algae collecting along the shore) were noted at north
shore sites particularly (Keeler Cove and Litchfield Boat Ramp) but neither was
serious at time of our observation however are likely to worsen in the days and
weeks ahead. Dissolved oxygen saturation
values mixed with about half the sites having saturation values below 100% and
half with saturation values between 100% to a maximum of 103%. 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. No anoxic water was found anywhere in the
lake.
