In Wisconsin, Isoetes (quillwort) is found in shallow lakes, from 0.5-3m
below the surface. There are several species, all of them smaller than the
ones with which I am familiar in the southern U.S. Ours are about 5 cm in
length. 

I have waded these lakes, and found the quillworts mixed with Juncus (as I
recall). The way to tell the difference is to pull them up and then gently
feel with you thumb and forefinger for the characteristic bulbous corm
(stem) from which the roots arise.
