53-acre lake near T16 R9 WELS. The lake tops out around 6 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
4th Pelletier Brook Lk maps at 53 acres behind 1.3 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. Aroostook County claims this one. Its nearest charted neighbour, 3rd Pelletier Brook Lk, is 1 mi to the north.
Spring brook trout on 4th Pelletier Brook Lk hold shallow, usually 1 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 1 to 6 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
