7.3 Comments Phase 1 confinement is estimated. No Phase 1 valley width has been entered. The channel was historically altered and appears to have come into the West Branch upstream of the current confluence. Phase 1 valley walls could not be drawn for segment M08S1.01-A because they do not exist naturally. Reference channel width is uncertain. SGAT generated width (12.4ft) is much less than phase 2 channel widths for 2 assessed segments (29ft, 22ft). Throughout upper West Branch, phase 2 channel width was consistently much greater than SGAT generated channel width, possibly due in part to natural reasons such as greater precipitation and slope in West Branch watershed.
