Parks and Lands, 2003 on. A boat can run the length of the lake. Coves may still hold ice. Reported as Cobbossee Lake.

DACF public boat launch table, export dated 5 June 2025. A blank fee is blank, not free. Ramp end and turnaround are not in this table.

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.

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

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.

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