Per Cody and my own unfortunate experience, YP need depth of 13'+ to escape Summer temps or your larger YP [12"+] will struggle. I lost 75 12-13" female YP in a 9' depth pond during Summer months...exactly as Cody preached, they were fine a couple seasons until they hit the 12"+ mark. Something to bear in mind even though you're more North of me.

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
