55-acre lake near Lenawee County. The lake tops out around 75 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Allen Lake runs 65 acres with 1.3 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 43% of this chart. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. You'll find it in Lenawee County. The nearest mapped water is Meadow Lake, 0 mi to the south.
Spring cisco (lake herring) on Allen Lake hold shallow, usually 10 to 40 ft. They move out to 23 to 75 ft in summer and finish the year down in 20 to 60 ft. Put Deep basin first on the milk run — a deep basin near 75 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (20 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 23 to 75 ft | dawn | Deep basin (75 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (20 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (20 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Break off the point. It's a drop-off holding about 20 ft of water and rates prime come summer. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
