Thanks for the mention @Blue Raider Bob. Now here's the bad news...I wish I could give you some great words of wisdom that would work for you, but I've come to believe that while 'a bass is a bass,' that only takes you so far. All success IS a local thing, especially when it comes to big bass.
I've been fortunate to be able to push the envelope by fishing as much as 175+ days a year or more for a few decades now, and I can tell you that there is no such thing as water that is too cold to catch bass out of. I've literally caught them in about every cold weather/water scenario imaginable, right up to drilling holes in a frozen lake. But how you actually catch them - what will work or won't work for your waters - is literally based on your waters, your approach restrictions (boat, bank, kayak, etc.), and lots of trial and error. While all of us could rattle off our favorite winter presentations and locations, there's no guarantees any of them would actually work for you where you fish.
You have to take the basics of a technique option and just give them a try. The same applies for location. We all are good at posting our successes, but what you rarely see is the hours and hours of our unsuccessful attempts with a variety of baits in a variety of locations - but that's how we learn, and what ultimately leads us to the good catches you eventually see.
But to try and be a little bit positive in all this, I will say if I had to start a list of my most successful winter baits, it would include things like blade baits, Ned rigs, jerkbaits, and hair jigs (bucktail or float-n-fly style). Those 4 will cover the water column from top to bottom. I could also say with some confidence that being near or in deep water (which is relative to your lake) is also important. Steeper banks (>45 deg.), whether that be creek or river channel bluffs on a larger body of water, or the deep water end of a pond, are a great starting point. And from there, the trial and error of baits, presentations, retrieves, exact location, best weather patterns, all play. When you do get a bite, consider it a data point that hopefully you can use to expand and build upon, leading you to your next bass. Go out there with an open mind, and know that it's an extremely rare instance in which there isn't a bass somewhere willing to bite on any given day
