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]
