I do a lot of scuba diving / free diving / spearfishing in clear water lakes and ive noticed that catfish love to get in cedars and crappie love to hang out about 5-15 feet over the top of them. The hardwoods seems like they actually get inside of the tree instead of on top or around it. Sycamores and willows bring some serious attention if the leaves are on them. Havnt dove any boo yet ... cant wait to this year hehe . All this info is comming from a 300 foot deep 20 foot of visibility lake so i dont know if murky water fish act the same but just my 2 cents
