Best subsets multiple regressions were used to
identify the independent variables that most closely
predicted the six dependent (chemistry) variables
using data from both sets of catchments (Table
8.2). Specific conductance had a strong negative
relationship with forest land-cover but also showed
relationships with an assortment of variables
reflecting development and commercial land-use
(Table 8.2, Figure 8.4). Nitrate was highly variable
among the catchments and related primarily to
land-cover variables (Table 8.2, Figure 8.5). Winter
turbidity was related to agricultural land-cover in
