My pond's fountain broke, fish seem less interested in biting nowadays

[TriStateBassin106]

So a 2acre pond I fish quite frequently had it's fountain break around 2 months ago a new fountain hasn't been replaced yet because the county park people are waiting for the township to get back to them, since then the fishing has been much slower for bass. No fish kill here because there's still plenty of bluegill and other fish swimming around and we are still catching bass but not as many as we would like or were used too. how does this effect the bass and what are some techniques we could do to catch them in this situation? My pond is a max of 7 feet deep and has water clarity of 6inches, we think their metabolism has slowed down because of the fountain being gone.
