Last year we pulled out 15 lbs to the acre of 10-18".
This year we pulled out 10 lbs per acre (seemed to catch less fish this year), everthing less than 18" pretty much again. This year i saw a more diverse size class of fish. We see bass from 6-20+". Also they were a lot healthier looking.
So to answer your question, without a shock survey i'd say the bass size class are spread out fairly decent.
