] The winter flow recommendation, which met 2 of 3 criteria fell outside the accuracy range (2.5 & 0.4 * Q) of the R2CROSS
model. However, because the estimated flow fell below the measured discharge and it was the flow required to maintain the
hydraulic criteria of average depth and percent wetted perimeter, the CDOW believes 0.5 cfs will protect the natural
environment to a reasonable degree.
