1,058-acre lake near T36 MD BPP. The lake tops out around 27 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, Fifth Machias Lake runs 1,053 acres with 7.9 miles of edge — one island included. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Roughly 70% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 2.4 mi end to end and 1.2 mi across at its widest. You'll find it in Washington County. The nearest mapped water is Gassabias Lake, 6 mi to the northwest.
When the water first warms, chain pickerel slide up into 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 5 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a weedless spoon + trailer or a buzzbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Break off the point (13 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Break off the point (13 ft) | Jigging spoon (through ice) |
In spring, white perch run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 8 to 27 ft, and winter fish settle into 8 to 27 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 4 ft, rated prime for spring white perch. Time it for early morning. You won't need more than a small spinner rig drifted or a 1/8 oz jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Creek inflow (4 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 8 to 27 ft | dawn | Deep basin (27 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 8 to 27 ft | midday | Deep basin (27 ft) | Jigging spoon (small), Blade bait |
| Winter | 8 to 27 ft | dusk | Deep basin (27 ft) | Small rattle spoon, Tungsten + spikes |
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 8 to 27 ft, and winter fish settle into 3 to 20 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 4 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Creek inflow (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 27 ft | dawn & dusk | Deep basin (27 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (4 ft) | Small jigging spoon, Tungsten jig + plastic |
