Here is the transparency
measured at Site 1 throughout our study. Notice that during the early testing, the transparency was
a little low, most likely due to sediments still in the water column from the
spring mixing event. However, as
the summer progressed, sediments settled to the bottom as the lake became
stratified, thus the increase in the transparency through the summer and into
early August. However, towards
the end of August and into September there is a sharp decline in the
transparency due to the onset of the fall mixing. However, compared to the 1985 transparency readings shown
here [Click for next picture] in red with the 2008 readings still in blue,
particularly in mid-summer, it is clear again that the lake has shown
improvement. This improvement in
the transparency is shown also in the historical phosphorus levels, which I
will talk about next. [Click for next slide]
