89-acre lake near T9 R11 WELS. The lake tops out around 7 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Upper Portage Pond maps at 89 acres behind 1.9 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.8 mi, about 0.3 mi across. It sits in Piscataquis County. Leadbetter Pond sits 3 mi southwest — the closest neighbouring chart.
When the water first warms, brook trout slide up into 1 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 1 to 7 ft. If you only fish one area, make it Deep basin: a deep basin around 7 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft | dawn & dusk | Deep basin (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft | dawn | Deep basin (7 ft) | Small jigging spoon, Tungsten jig + plastic |
