I Field Data Collection Procedures
The following sequence outlines the field measurements at each study site. Field data
collection occurred from June through September.
Habitat Mapping
Habitat mapping was conducted as a means to detect changes in habitat conditions that
could affect fish and macroinvertebrate populations. Habitat mapping was completed for
various distances around each study site based on access. (Habitat mapping used a
protocol developed by Pike & San Isabel National Forest basinwide survey (Winters and
Bennett 1994)). This protocol allows the quantification of specific instream and
streambank parameters. Data collected during mapping by the field crew included
habitat type, length, width, structural association, substrate type, bank erodability, bank
rock content, and presence of large organic debris. Field data are input into a computer
spreadsheet and analyzed using the basinwide program developed by the Pike & San
Isabel National Forest.

abitat type to represent the hydraulic conditions within
each habitat type. Additional transects were placed at hydraulic locations within the
habitat type to ensure better model calibration and simulation.
I Ground survey
Vertical elevations were established throughout each habitat type by establishing a
relative benchmark at each study site. Each study site was surveyed using a standard auto
' level and differential leveling. Specific stream cross sections were surveyed for use in
the hydraulic model. Multiple data sets of water-surface elevations and point velocity
measurements will be used to calibrate the hydraulic model to simulate depth and
