Abstract FishXing (fish crossing), a computer aided stream crossing culvert model designed
to analyze fish passage through culverts was compared with results of an Oregon
Department of Forestry fish passage monitoring report. FishXing was created at
Humboldt State University through sponsorship from the US Forest Service,
USDA, Stream Team, Six Rivers National Forest, San Dimas Technology and
Development Center, The Watershed Stewards Project, and the Federal Highway
Administration. A comparison was made between results generated using
FishXing with results found by ODF in the Oregon Department of Forestry (ODF):
Compliance With Fish Passage and Peak Flow Requirements at Stream Crossings
monitoring project. Stream crossing culvert data from the ODF fish passage study
was used to run FishXing. The ODF monitoring project investigated 74 fish
passage culvert installations that were constructed following approval of Written
Plans filed with ODF in 1998. (An approved Written Plan is equivalent to a permit
with ODF). Information about culvert installations was analyzed using FishXing.
Four different trials were run for each culvert using both adult and juvenile Coho
Salmon and Cutthroat trout using the FishXing software. Three trials used the
default values for swimming abilities of adult and juvenile Coho salmon and adult
Cutthroat trout. Juvenile Cutthroat trout were also included in the comparison;
however, FishXing did not contain a default setting for them. Therefore, a velocity
of 2 feet per second (fj,$), the current target velocity for stream crossings on fish
111
bearing streams in the state of Oregon, was used for juvenile Cutthroat trout
(ODFW 2).
After making comparisons with the preliminary ODF results, further study was
done to assess the accuracy of the calculations carried out within FishXing. This
was based on Manning's equation (V=1 .49/n*R2"3*Sh"2) and other formulas given in
the "help" section of FishXing. Flow calculations were also compared with the
Haestad Culvert Master program. The results produced using Manning's equation
show no statistical difference from those generated using FishXing. Furthermore,
there was an insignificant statistical difference found between FishXing-generated
output and that of Culvert Master. Positive and negative attributes concerning
FishXing are addressed at the end of the report.
