Check my post on Croton. I was out Saturday and the LM bite was on. The majority of our fish came on Jig&Pig fished slowly off the bottom. We kept the boat in 15-20 feet of water with the bulk of the fish coming from 8' of water or less. We did get a few from the deep weedline, but the majority of the fish were shallow. My partner picked up 2 fish on a jerkbait and I got a beauty of a smallmouth on a crankbait, while trolling from one spot to the next. My boat is on the SW part of Croton, west of the Taconic bridges. We fished the shoreline up to and between the Taconic bridges as well as a few small coves on the south shore towards the dam. Thoroughly fish the weeds from the Taconic bridge into the small cove with the waterfall in the back. We picked up a few here, and I'm sure we would have caught more if we spent some more time there.
Don't fish too fast. You wan to keep the boat moving to cover some water, but I would stick with the jig and work the likely areas thoroughly. Look for rock and weed combinations and thoroughly work any points or other structure. We didn't have any luck on wood, but two weeks ago I picked up a few on downed trees.
Hope this helps, and good luck!
