Thanks for chiming in with the info from Poway. What you described with the larger trout being stocked, and the subsequent decline in largemouth bass size fully 100% validates exactly what I figured was happening.

We've seen this exact scenario in several of the Bay Area Lakes. Big bass just don't do well feeding on 2lb trout. The biggest bass will go after them, but I believe sincerely that even an 18lb bass would rather eat a 7 to 10 inch trout.

Do you know what the rationale is at Poway for not stocking DFG trout? Is it frogs or something else? Does anyone have a copy of the Pre Stocking Assessment Protocol document to review? You know, because I'm sure that stocked trout have certainly ruined some native species' life at Lake Poway, a totally man made lake :(.
