1,672-acre reservoir near Franklin. The lake tops out around 25 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. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 1,578 acres of water rimmed by 18.3 miles of bank. A development index of 3.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 32% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 4.7 mi of water from one end to the other, 2.6 mi at the beam. The nearest mapped water is Taylor Pond, 4 mi to the east.

Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
