Laterwhen the lake began to subside and the delta emerged as land sur-face the river became gradually confined to the Mohawk channeland flowed in great volume and with high velocity in that portionof the channel which now forms the basin near Schenectady.(2) But the preglacial channel of the Mohawk from near Schenec-tady eastward had been filled by deposits and the waters now cutDfT from the old outlet sought the lowest levels of discharge leftop
