The lake I fish most often and hvae the most success at has dropped about 3 feet. I was catchin fish on the bank with a spook. I hadnt been there in 3 or 4 days and today when i got there I noticed it had dropped. I wasnt sure of what to do so i tried fishing deep docks and didnt have succes. Im I was fishing badin lake in nc and the water temperature was in the mid 80s. Mostly 84 where i was fishing. What do the fish do when the water level drops?

Most cases they're going with the water. They will find that next good spot just a bit deeper.

One place is very low my son's caught panfishing only. From shore the bass are deeper in the middle.

One reservoir is 9' lower than normal. I think we're in a drought. Some towns have restrictions on using water.

9ft isn't low, try 120ft below full pool.  Now that's a bit low.  Back to the OP, is the water still falling or has it stablized?  Most fish will like stated pull back to the next best area.  Find areas that are in the 5-6ft range (at full pool) with cover and contours, odds are thats where they probably shifted to.

3 vertical feet of water change in a day is a lot of water, if the shoreline dropped 3' from where it was the depth change depends on the slope of the bank, 3" vertical drop in water level can move the shore line several feet if it's a slow tapering bank.

The basic rule of thumb is bass move out as the water level drops quickly and move up when it raises quickly.

Nearly everywhere the water temperatures are dropping and water temperature change affects bass location, they move out into deeper water where the baitfish moved to.
