It was small compared to the Great Lakes, but the lake had a fetch of a few
miles.

I have been on small lakes in a storm with 20 knot winds, that had 3 to 5
ft. waves,

no you haven't. 20 knots winds take a long time and long fetch to get to
be 3
to 5 foot waves, and even then you need water most usually deeper than is
found
in a "small lake".
