I'll see if I can help. When I first started bass fishing, I would go months without catching any. Since then, I've started finesse fishing more, slowing down, etc. and I can catch around 1 per week. I would definitely try the ned rig if I were you, (get the real thing, it's much better than a senko and jig head or something) it's really easy to fish, and works when nothing else will. However, if you want to just sit still without retrieving a lure the whole time, I would use some kind of bait. Live bait, lunch meat, nightcrawlers, anything like that. Also, if you see someone fishing there you should ask them if they've caught any, what lures work, etc. Hope that helps.
Edit: Here's the link to the ned rigs: https://www.amazon.com/Ned-Rig-Kit-Finesse-Shroomz/dp/B01AYMNIT8 You can get them from pretty much any tackle shop, or online.
