80-acre lake near Johnson Landing. The lake tops out around 30 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
Spring brown trout on Florence Lake hold shallow, usually 3 to 25 ft. By summer they slide out to 9 to 30 ft, and by winter most fish are in 4 to 30 ft. If you only fish one area, make it Creek inflow: a inflow / creek mouth around 28 ft that scores prime in fall. In summer the feeding windows fall in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
