Finding the big bass pattern

Today I’m fishing A-1 retention area of the Everglades, a 17,000 acre impoundment. Regulations only allow cartop small boats , no trailers allowed , so I’m using my 1542 Jon boat. The problem today is that it’s hot, sunny and with no water movement . Bad pattern conditions. I catch a few small ones on topwater, a few more on worms against the hyacinths and next to nothing on a spinnerbait and a Chatterbait late in the afternoon I try worms in the deeper stickup and immediately started catching big trophy bass. I figured out the pattern!
