Arthurs Lake has several boat ramps serving anglers and recreational boaters on this popular Tasmanian highland fishery.

The Jonah Bay Boat Ramp, situated along Gunns Marsh Road off Poatina Road in the Central Highlands, is owned by Hydro Tasmania and features a dual-lane concrete ramp with a central pontoon platform, car parking, and toilet facilities.

A white navigation light is located on the shore nearby. The ramp provides access to the upper reaches of the lake and is a well-regarded launching point for trout fishing.

The Arthurs Dam Boat Ramp, also owned by Hydro Tasmania, is a second dual-lane concrete ramp with a central pontoon platform located near the dam wall at the southern end of the lake.

Both ramps are recommended access points, though water levels can affect usability — the Jonah Bay ramp in particular may be restricted during periods of low water.
