The good news is that it looks like you can cast every square foot of that pond so that gives you the opportunity to throw just about any bait, anywhere.
I fish a ton of small lagoons here in SC and what I have found the past few weeks is that the bass are cruising around a lot instead of hunkering down in one area. Afternoons between 2 and 5 have been great times to fish lately, whereas in the summer 6-9 in the evenings was best. They are also hitting on baits different than in the summer.
In the summer T-rigged Senkos, trick worms, jigs, frogs, buzzbaits, crankbaits, and the Whopper Plopper worked best. I couldn't even catch a cold with a crankbait. But lately my Purple Tiger Rat-L-Trap has been crushing it with both LMB and crappies. I've also caught 5+ pounders with an 8" worm that I found on shore one day.
But lately except for the Whopper Plopper none of my summer baits have produced in the last 3 weeks. For me it ended up being fun throwing stuff I haven't thrown in a while and actually catching good sized fish on those lures. So what I'm getting at here is if nothing is biting on your go to baits try some of the stuff you normally don't throw and see what happens. You have an advantage because you can pretty much cover the entire pond.
In the mornings and evenings throw some top waters over and around the mats. But the rest of the day throw everything and anything everywhere. My experience here in SC tells me that the cooler water in these small ponds will have the bass cruising around looking for their next meal. Whatever you do cover lots of ground. Fan cast from one spot and if nothing is there move around. When you get to the end throw on a different bait and repeat.
If there's bass in there you'll eventually run into them with the right bait. Take advantage of the small pond.
