what are the best conditions to fish, does weather affect fishing.

working a spillway today caught 2 largemouth on strike king chartriusse and black back 1.5 crankbait silent. They wouldn't touch the ones with the rattle. water clarity is about 2 feet. Water wasn't to fast so what do i use that will be better for the fast water about 4 feet deep. there is hybrids and largemouth in there just struggling to get bites. rocky bottom.
