All great answers.
But, I’ll relate a time when Lusk bushwhacked me. I heard that he was going to be at a local farm store talking about ponds. He is a Purina spokesperson and the store was selling it.
About ten minutes into his presentation, he said “ Hey Dave Davidson, what’s the most important consideration for a new pond?”. I said a few things about clay content , adequate runoff, etc.
He agreed that those were certainly important but said the most important thing is the water, it’s fertility, balance of alkalinity, Ph, and stocking rates.
That’s when I felt like slapping my forehead and feeling like an idiot.
