I have been having mild success with square bill crankbaits at my heavily pressured local city lake. This has happened several times, whereby, I try a spot and I get bit. After I catch 1 fish, I have no more luck, not with the lure that was originally used, nor any other color or type crank. And I also do not have luck with any other type of lure.
This is sort of a pattern there, I've gotten multiple fish with texas rigs or square bill cranks. It's quite rare to catch more than 1 fish from the same spot though, and by that, I mean, after I cast to the same spot I think I got bit for a dozen more casts, I resume fan casting and have nothing else regardless of what I throw. Once in a while, I'll catch one, then closely after, catch another.
Sometimes I persist and fish another half an hour before changing lures, and usually an hour before changing spots. The best myself and my buddy has ever done was 3 bass and 3 crappie together on crankbaits. That happened 1 time, earlier this year during late winter.
The pressure this lake sees, at least in the spots that I fish; every nice day from about 4:00 until about dusk, probably 30 people fishing in that time and more on the weekends. Now... not everyone is bass fishing, and not everyone is dedicated. Some people walk the bank and make a few casts as they walk, others, like me, pick a spot and fish it an hour before moving.
There is 1 corner, which looks really good with lots of stickups and brush that happens to be the first spot off the parking lot, it sees a tremendous amount of pressure. Everyone that passes by tries it. I have caught 1 fish on it, right after a rain (I surmise the fish know that people go in during a rain and they figured the pressure was off). I've never seen anyone else catch a bass there.
Last year I focused on learning this lake, and fished it 2 or 3 times a week. I tried a lot of different stuff, paid attention to what others used, and what I found, and generally tried to learn where the fish hang out and what might work for them.
I caught bass on, or had solid strikes on:
cranbaits, square bills
texas rigs using lizards, senko, 4" grub (most in green pumpkin)
spinnerbaits
whopper plopper
soft body topwater frog
beetle spin
spit'n image
buzzbait
4" hard swimbait
I have seen others occasionally catch bass on:
rooster tails
jerkbait
ned rigs
swim jig
chatterbait
lipless crankbaits
popper
I fish all those things, though some not as much, like I rarely fish a ned rig, but I fish lipless some, and chatterbait some, and fish a WP pretty often.
I've fished a jig a lot, never with a bite though. I've tried a bit of everything, lots of colors, lots of varieties.
Some things that I was sure would work, like the spit'n image (only caught 1 fish) didn't work (fished it a LOT). That lure isn't available in the stores here, nor at cabelas 50 miles north, so it's less common I'm sure. Another thing I'd thought of that I was sure would work, was a lipless crank with a blade on the tail in place of the hook. I doubt they see many or any of those... I fished a red eyed shad so modified for a good stretch and never a nibble.
Some things that you'd think wouldn't work, seem to be the best producers. All of the soft plastics I've had success on were green pumpkin color. Lizards rigged weightless Texas rigged worked the best so far. Changing color of the lizard failed to produce anything other than 1 nibble on a black/blue.
My buddy has good success on rattle traps... but I do not. I've thrown some traps, some super spots, and some red eyes, and never had a bite on them. Lost a few though.
I have good success on square bills, and he does too, which surprises me because they are quite popular. I choose colors that might not be as popular such as gold, or American shad, but never sexy shad. Though a friend caught a bass on a sexy shad colored square bill one day while I was there.
The main reason I fish this lake is because when I go to town with my wife and kids, it's convenient for us to swing by there a few hours. My wife likes it; porta potties, walking trails, mowed grass. Now, sure I'd like to find a "better" spot, and I have a few other spots with less pressure, but that aren't as convenient, and often it's either fish this a few hours or not fish.
I figured last year I'd use the opportunity to better my skillset. I started learning more about what fish/bass like; structure, wind, water temperature, lure selection and color for the conditions. And... I did get bit some. Now.. I ain't having 5 and 10 fish days (half days). But others I talk to, some at least, say they don't ever catch anything, or they only catch very rarely. I find that about every other to every third time I go for 2-4 hours, I do get one.
I have put my boat in there a couple times, and it seems the bass are more apt to bite along the shorelines that don't have bank fishing access. That said... I still want to focus on getting bit in the regular bank spots as I can't put my boat in as often as I'd like.
There is no night fishing at this lake, so I suspect the bass have learned that and adapted. I talked to several people that said the fishing is better in the mornings IE: very little pressure. I have fished it in the mornings only a few times and I didn't see any difference (I realize a few times isn't enough to make a determination).
I suppose my point in this post is that I'm asking for advice on how to approach these waters... something that'll give me a bit of an edge. Advice of any kind is appreciated.
