ewest, I have a standpipe 30" with a 48" trash rack that extends 7 feet below the surface. We may go for 3 to 5 weeks without rain then one thunderstorm will put 2 to 3 feet of water over the top of the trash rack which sends most all your fertilize down stream. It might be possible to develop a good bloom from May until July, but that short time frame will hardly accomplish an above average fishery. It might not be as disappointing to try the fertilize and feed combo you mentioned, verses the fertilize and dye program.
