YEAR<br />
Water temperatures during the<br />
summer months generally<br />
varied between 20 and 30 o C<br />
over the study period (Figure<br />
66). The LOWESS curve<br />
indicated no systematic trend<br />
over this period in the cove.<br />
Linear regression analysis also<br />
indicated no trend in water<br />
temperature in the cove (Table<br />
10).<br />

YEAR<br />
In the river summer<br />
temperatures have occupied a<br />
similar range to that in the cove<br />
(Figure 67). The trend line did<br />
show a little dip in the mid-<br />
1990’s, but it was less than<br />
0.5 o C. Linear regression over<br />
the study period was also non<br />
significant (Table 10).<br />
