I’ve got two rock quarry’s the biggest one is about 60 feet down all the way around the smaller one if I had to guess is about 40 feet deep at most. Anyways i have trouble catching bass in both in the small one if I use a new lure I will catch a decent amount for the first couple of days but after that it’s the like bass remember that it’s a lure even If I stop using it for a year they won’t touch it again with the exception of jigs but I still catch very few on them. The bass in the small one are mostly 1 pounders with a few long but skinny 3-4 pounders. In the big quarry there’s a lot more bass and bluegills and the bass are a lot more heathly with big belly’s. I have better luck in the big one but I still catch 3 a day at most and I can switch up my baits and fish all day it doesn’t matter in both quarry’s the bass seem to love brush hogs when it’s freezing outside im talking in the twenties. Anyways the big rock quarry's bottom is covered in dead trees, mining stuff, pipes from when they tried pumping the water out, cars, car stuff, ovens, couches. I mean it's not like trashed but there's a cop car down there an oven and a couch and a ton of trees. The water isn't that clear in either. Kinda greenish brown. Sorry for the spelling errors if you have any advice please give it.
