Fishing Crapo Lake: what the data says
126-acre lake near Otsego County. The lake tops out around 36 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. What follows comes from the same scoring engine that paints the spots above.
Rock Bass fishing at Crapo Lake
Start shallow in spring: rock bass sit in 2 to 10 ft that time of year. By summer they slide out to 5 to 20 ft, and by winter most fish are in 12 to 30 ft. If you only fish one area, make it Main-lake point: a point around 6 ft that scores prime in summer. In summer the feeding windows fall in the evening. A ned rig (small) or a marabou jig covers the summer program.
