I have yet to have an even decent day bass fishing at Marrowbone. It's a shame because it's a beautiful lake and seems like the kind of place they should be thriving. Maybe they are, and I'm just terrible out there
It has crystal-clear water throughout the lake. I wonder if they stay relatively deep all year round. I am no deep-water fisherman for sure -- but I am working on it.
I have had some of my best days on Shellcracker and Blue Cat at Williamsport. In February on Blue Cat I caught 16 Largemouth, two nice Hybrid, and a monster Crappie (biggest I have ever seen). Blue Cat has better (read: actually has some) structure. You can find clay bluffs, rock walls, gravel points, weedlines, etc.
Shellcracker is where my personal best came from, and I caught two approximately the same size in the same late-afternoon/evening. See profile pic. Didn't have a scale, but she was about 23 inches and fat. I really feel the key there is do anything, but do it s-l-o-w. I have never had a topwater strike on that lake. I've caught them on just about everything else in the tackle box fished v-e-r-y s-l-o-w.
Shellcracker's biggest targets get beat up constantly, but still consistently produce. Laydowns and submerged timber along the banks, riprap at the dam, and the culvert at the back of the left-most major creek arm all hold fish. I have never had any success on the riprap but that's my fault because I know people catch monsters there year-round.
If you can't tell, I like these little lakes a bit.
