This figure depicts the
monthly average Secchi depth for sites 1-3 this summer. Site 4 was too
shallow for Secchi measurements. In the figure, average secchi depth is
plotted on the Y axis, and date is along the X axis. This figure shows us
that although bottom phosphorus levels are increasing, Long Pond North is
still not experiencing major algal blooms, because Secchi depth never fell
below 2 meters. This is good, but when we look at historical data, we get a
different picture.
