We also have CC, with the largest caught was last fall at 13.5 lb. Our pond is a 10 A. rock quarry. The one thing that has always confused me is any time we catch a BCP they are very healthy and nothing thin like we catch in the Mississippi or lakes near us. Our BG are different age classes to show good recruitment over the years. The last few years we have added a lot of structure both in shallow and deep water but does not seem to help our BCP. From what I read maybe we should consider ourselves lucky but in 10 years nothing has changes with our Crappies.
