B: 157 - Stream Habitat Surveys

Conduct single habitat survey at each of 50 randomly selected stream sites in the Wenatchee basin as identified by the Regional Tech Team (RTT) and NOAA Fisheries; reviewed by the U.S. Forest Service and the Chelan County Conservation District.

General
Characteristics Specific Indicators Data to be Delivered for Each of 50 Sites (1 visit each)
------------------- ----------------------------- -----------------------------------------------------------------------------
Site Description Site number (from Sample Site List); stream name, short
site location description (e.g., Trout Creek upstream of
Pine Campground); actual coordinates (decimal degrees)
of x-site; field crew member name; date(s) sampled; time
began sampling; general weather description on day of
sampling, narrative comments about the site including
any unusual habitat features or notes regarding site
location or access.
Habitat Quality Dominant substrate Raw pebble count data at 105 measurement points;
site-calculated dominant substrate size.
Embeddedness Raw embeddedness data at 55 measurement points;
site-averaged embeddedness percent.
LWD Site-total count of LWD pieces within each of three
size categories (pieces/km).
Pools Site-total count pools (pools/km).
Residual pool depth Raw residual depth of each pool; site-average residual
of all site pools.
Fish cover Percent class by area of stream covered by each of 9
cover types at 11 measurement points; site-averaged
percent class for each of 9 cover types.
Off-channels habitats List of each off-channel habitat unit by type; length of side-
channels; site-total count of each of 3 types of off-channel
habitats; site-total length of off-channel habitats.
Macroinvertebrate Macroinvertebrate sample.
Channel Condition Stream gradient Straight-line distance between transect/thalweg
intersections; straight line length of sample-site;
elevation drop between transect/thalweg intersections;
total elevation drop over sample site; site averaged
stream gradient.
Width/depth ratio Site averaged width/depth ratio.
Wetted width Site averaged wetted width.
Bankfull width Site averaged bankfull width.
Bank stability Percent of the lineal distance of bank that is actively
eroding at the active channel height at 22
measurement points; site-averaged percent of the
lineal distance of bank that is actively eroding at the
active channel height.
Entrenchment Ratio Entrenchment ratio calculated at each measuring point;
site-averaged entrenchment ratio.
Sinuosity Site-averaged sinuosity.
Riparian condition Structure Percent class of areal cover (by three vegetation classes)
at each of 22 measurement points; site-averaged percent
class of areal cover (by three vegetation classes);
vegetation type will be described at each of 22
measurement points.
Disturbance The presence (11 classes) and proximity (4 classes) of
human land-use activities in the riparian area of 22
measurement points.
Canopy cover Raw canopy cover data at 66 measurement points; site-
averaged canopy cover.
Reach
Characterization Channel type (Rosgen) Predominant Rosgen Level 1 channel type within site
based on sinuosity, entrenchment ratio, width, depth ratio,
and slope; notes if site encompasses more than one
Rosgen channel type.
Bed-form type Predominant bed-form type within site; amount of
confinement within site.
