26-acre lake near T3 R10 WELS. The lake tops out around 21 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
On the chart, Lost Pond draws 26 acres inside 0.9 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 94% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. You'll find it in Piscataquis County. The nearest mapped water is Foss and Knowlton Pond, 1 mi to the southeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 6 to 21 ft, wintering in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 21 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
