30-acre lake near Comstock Twp. 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. Every species below gets its seasonal read from the same numbers driving the chart.
Upper First St John Pond maps at 29 acres behind 1 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. It sits in Somerset County. Its nearest charted neighbour, Lower First St John Pd, is 1 mi to the southeast.
Come spring, look for brook trout tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 1 to 7 ft. Start at Deep basin. It's a deep basin holding about 7 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
