45-acre lake in Fulton County, Indiana. The lake tops out around 39 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.
On the chart, Fletcher Lake draws 45 acres inside 1.3 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 34% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.5 mi, about 0.2 mi across. You'll find it in Fulton County. For a second option, Nyona Lake lies 9 mi northeast.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (13 ft) | Squarebill crankbait (shad), Spinnerbait |

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite.
