4-acre lake near Greenville. The lake tops out around 18 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.
Grenell Pond maps at 4 acres behind 0.4 miles of shoreline. Its 1.2 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. Piscataquis County claims this one. Secret Pond sits 1 mi south — the closest neighbouring chart.
Spring brook trout on Grenell Pond hold shallow, usually 2 to 15 ft. They move out to 5 to 18 ft in summer and finish the year down in 3 to 18 ft. Put Deep basin first on the milk run — a deep basin near 15 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.
