325 Rock River

of Lake Winnebago, it is inferred that a canal might be opened so as to drain water from the lake as a reservoir into the river." That this inference is very far from correct is shown by statements made in the reports of the same officer. The level of Rock river is stated by him at a point some distance below Johnsons rapids to be 180 feet above Lake Michigan. To this should be added for those rapids and two others above, and also for the descent of the river between the rapids, about 136 feet above Lake Michigan. But Lake Winnebago is stated by Capt. Cram to be only about 160 feet above Lake Michigan, so that in order to make its waters run down Rock river a "deep cut" must be excavated 166 feet deep and extend from the lake nearly to the Illinois state line! That a canal may be made here is perhaps true; but that some [other] source for the [of] supply of water other than Lake Winnebago, is also true.
