Aquatic habitat parameters were measured and mapped at each site within the exact area
where electrofishing was conducted. Water quality was similar between Sites, with
slightly higher temperature at Site 1 and slightly higher conductivity at Site 2. Water
quality data is reported in Table 3. All parameters are within acceptable levels for warm
water aquatic biota.

Habitat mapping at each site consisted of quantification of specific physical habitat
characteristics. The length of the stream channel at each site was divided into three basic
habitat types (Pool, Riffle and Glide). The total area of each basic habitat type was then
