There's some useful information on the USGS and EPA websites that might help.

I took a test at an invitational a few weeks ago and there was a lot of stuff on it about lakes, mainly stratification, but also a few other general questions about formation. I have had trouble finding any information about lakes and was wondering if anybody had any suggestions about where to look, aside from google of course.
Thanks.
Most physical science books have chapters on lakes and rivers..

The images you can find for stratification and turnover can help with basic vocab knowledge.

Is there an official form of Darcy's Law? I have seen many versions, such as
Q = KIA
Q = KA[(hA - hB) / L
Q = Q = KA(dh/ dl)
I'm just worried that it will be on the test and I'll put the wrong one... yeah.

The version I found is Q = KA(dh/dl), but I think all of the ones you listed are equivalent.

What books are you using? I've found a few physical science books, and all of them have chapters covering the basics of streams, however none of the ones I've looked at have information about lakes.

Alright, I'll use that one on my cheat sheet.
Random Question: Has anyone noted the odd relation of Michigan and water? Almost all of the sites I've used to study about Dyn Pnt and Awesm Aquif mentions something about Michigan.

Only Div. C needs to know about laws and equations. I think Michigan has a wide range of ecosystems, but most of the states in the Great lakes area are the same, so I can't say much past that.

Because the Great Lakes region is where it's at! For this, anyways. MI and MN both are loaded with lakes. Michigan's in the heart of it...it's
split, after all.

I've seen flow rate calculations on some of the B tests that I've looked at, and there's nothing in the rules that suggests that they can't put equations on B tests.

Sorry, I meant the conductivity and more advanced calculations, not gradient.
