939-acre lake near T41 MD BPP. The lake tops out around 9 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
On the chart, Gassabias Lake draws 937 acres inside 9.5 miles of shoreline — 6 islands included. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 1.9 mi, about 1.4 mi across. You'll find it in Hancock County. The nearest mapped water is Duck Lake, 4 mi to the north.
Come spring, look for chain pickerel tight to the bank in 2 to 9 ft. Through summer count on 2 to 9 ft; the winter hold is 3 to 9 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning and the evening. A weedless spoon + trailer or a buzzbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 2 to 9 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 2 to 9 ft | midday & dawn | Shallow bay flat (1 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 3 to 9 ft | dawn | Shallow bay flat (1 ft) | Jigging spoon (through ice) |
Spring puts white perch in skinny water — 2 to 9 ft is the zone. Summer fish stay in 3 to 9 ft, and winter fish hold in 3 to 9 ft. Summer white perch concentrate at Deep basin, a prime-rated deep basin around 9 ft. Warm-month bites cluster around early morning. A small spinner rig drifted or a 1/8 oz jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk | Creek inflow (1 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 3 to 9 ft | dawn | Deep basin (9 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 3 to 9 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Blade bait |
| Winter | 3 to 9 ft | dusk | Deep basin (9 ft) | Small rattle spoon, Tungsten + spikes |
Spring pumpkinseed on Gassabias Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 9 ft in summer and finish the year down in 3 to 9 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 9 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 9 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | dawn | Deep basin (9 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, yellow perch slide up into 2 to 9 ft. There's no big seasonal slide here — summer means 3 to 9 ft, winter 3 to 9 ft. Start at Deep basin. It's a deep basin holding about 9 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
