Clarification
This part of the article...

"In 1848, the Calumet Feeder Canal was constructed to carry water from the Calumet system at Blue Island to the Illinois and Michigan Canal, which was suffering from low water levels. This reversed the flow of the Grand Calumet"

...is not true. The feeder's source was on the Little Calumet upstream of the dam, and I've not seen a source detailing that it took enough of the Little Calumet's flow to significantly draw down the water level of the Little Calumet immediately downstream of the dam. If it did cause the Grand Calumet to reverse, it'd have been even more directly in that the lower water level upstream of the confluence of the rivers would have then simply reduced flows out of the mouths of this system at Calumet Harbor and Miller Beach. I wouldn't call that a "reversal" of the Grand Calumet, just a decrease in flow. The Grand Calumet wasn't being pulled upstream toward the dam on the Little Calumet just because the dam was built.--Criticalthinker (talk) 11:08, 24 January 2024 (UTC)
