What tease! This great map begs for my close scrutiny. Alas! It will not bear it.
Edit: Here is a decent hi res map of the watershed. Boy, do I want to read every detail of that map you shared, OP. I’m going down the rabbit-hole!
Edit2: Another mid/low res map of the basin, but its awfully MS-Paint.
Edit3: found this digital version, but no better, really:
EditFinal: Here’s a depth and elevation profile that I found that’s clear and fairly detailed. I am too busy today to get further sucked in, but I could spend the rest of my day staring at these maps…
Honestly, for how much fresh water they hold, I’m surprised how small their watershed is.
Fun Map Facts!
Lake Michigan resembles a penis.
More like one of those vibrators with the tickley things at the base of the shaft.
That’s a surprisingly small watershed for such large lakes. Does it rain a lot or is it just accumulated over a very long time?
Awesome map!
But! Should Huron-Michigan count as one lake, or two, or three?
