1,890-acre reservoir near Fishers. The lake tops out around 38 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. Here is how the season plays out for each species, straight from the data behind the map.
Geist Reservoir maps at 1,857 acres behind 38.5 miles of shoreline. With a shoreline index of 6.4, this water is all arms and coves — edge habitat well beyond its acreage. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 5.8 mi end to end and 1.8 mi across at its widest. Hamilton County claims this one. If the bite dies, Morse Reservoir is 14 mi to the northwest.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
