Branch Lake Boat Ramp in Ellsworth features a hard-surfaced ramp (20' wide, 67' long) with a 13. 5% grade and accommodates trailered boats with 25 parking spaces available.

As Branch Lake is Ellsworth's drinking water source, all boats must pass inspection for aquatic invasive species before launching—inspections are available on-site when staff is present, or boaters can take a free one-hour self-inspection certification course to launch at their convenience (note: personal watercraft require staff inspection).

The ramp operates seasonally with extended summer hours (5 a. m. to 8 p. m. in June-August) and includes accessible facilities.
