Sailing out of Lake Pontrachain, my chart shows 9-15'just about
everywhere. My depthfinder is set at 6.6 as a min...

just before the last bridge it starts pinging like crazy.. I'm all
aflutter wondering if I'm going to ground-out in open water???...

... till I look at the readout which says 77'!!

There is a deep hole in a bend in open water...

Phew

Most of my sailing has been done in deepwater areas like southern
California, where "shallows" meant 25 to 50 feet. Coming to Green Bay has
done little to change my attitude about what shallow water is. There are
lots of places here where the water is less than 10 feet deep -- I simply
avoid them. Oh, I'll anchor in 8 feet, but only with someone on the bow (of
course) and someone watching the depthsounder and the boat ghosting along.
But sailing in that depth? Only in a dinghy if I have anything to say about
it. ;-)
