495-acre pond near Washington. NH GRANIT / NH Fish & Game survey water. The lake tops out around 25 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 495 acres, worked by 4 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 94% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.7 mi, about 0.8 mi across. Sullivan County claims this one. If the bite dies, Millen Lake is 2 mi to the northeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
