313-acre lake near Missaukee County. The lake tops out around 8 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.
Traced from the shoreline, Lake Sapphire runs 285 acres with 3.7 miles of edge. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Tip to tip the water measures near 1.3 mi with a 0.6-mi widest point. You'll find it in Missaukee County. Closest neighbour on DepthScout: Crooked Lake, 2 mi northwest of here.
Early season walleye use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. Put Break off the point first on the milk run — a drop-off near 5 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
