• Case Number: 07CW0117

• Instream Flow App - Doc Type: Supplemental Data

and runs will also be maintained for most life stages of fish and aquatic invertebrates (Nehring
1979; Espegren 1996).
For this segment of stream, three data sets were collected with the results shown in Table 1
below. Table 1 shows who collected the data (Party), the date the data was collected (Date), the
measured discharge at the time of the survey (Q), the accuracy range of the predicted flows
based on Manning's Equation (240% and 40% of Q), the summer flow recommendation based
on meeting 3 of 3 hydraulic criteria and the winter flow recommendation based upon 2 of 3
hydraulic criteria.

(1) Predicted flow outside of the accuracy range of Manning's Equation. ? = Criteria never met in R2CROSS Staging Table.
Table 1: R2 Cross Data
The summer flow recommendation, which meets 3 of 3 criteria and is within the accuracy range
of the R2CROSS model is 5.50 cfs. This recommendation was derived by averaging the results
of the three data sets. It is our belief that recommendations that fall outside of the accuracy
range of the model, over 250% of the measured discharge or under 40% of the measured
discharge, may not give an accurate estimate of the necessary instream flow required.
