180-acre lake in Essex County, Massachusetts. The lake tops out around 55 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.
On the chart, Crystal Lake draws 180 acres inside 2.3 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. About 67% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1 mi with a 0.5-mi widest point. The water lies in Essex County. For a second option, Captain Pond lies 1 mi west.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
