789-acre lake near Greensboro. The lake tops out around 142 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 the data behind the map says about each species, season by season:
The drawn water covers 788 acres wrapped in 5.6 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. About 14% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.6 mi with a 1.2-mi widest point. It sits in Orleans County. Its nearest charted neighbour, Lake Elligo, is 3 mi to the northwest.
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Main-lake point: a point around 12 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
