Rich, if you're 6'3", then let's just up-size my dimensions a tad, since I'm 6'1". It is 22" off the ground to my kneecap (which I remember because it is the 'correct' height for cutting alfalfa in bud stage to make dairy quality). Let's split your 2" diff - 1.5" above your waist, 1.5" below. Call it 24" to your kneecap.

Call that water 20" deep at least.

Holy crap, that's a lot of precip.
