Public camps

No public campground or reserved-land unit is linked to this lake. That is a blank, not a claim that a private campground is absent.

Invasive plants

DEP aquatic invasive layer. A point is the water, not the plant patch. Current means the record is still marked active.

Swollen bladderwort Current Acton, Shapleigh

Stocking

Not in the 2026 year-to-date IFW stocking report, or the water name did not match this lake. A river stocking is not listed here.

Same 8-digit watershed

Other DEP lakes that share this HUC-8. That is the drainage bowl, not “this stream dumps into that pond” for every row.
