Located on Victoria Valley Road at Spillway Bay in Dee, Central Highlands of Tasmania, the Dee Lagoon Boat Ramp is a single-lane concrete ramp with a timber landing stage owned by Hydro Tasmania.

A white navigation light onshore aids navigation, and the ramp is usable by all vehicle types. Past maintenance work included removal of submerged logs and installation of foot wire on the timber landing.

Parking is limited, with most visitors using roadside space along Victoria Valley Road. Facilities are minimal — a picnic table and basic cleaning table are on site.

The ramp is a popular access point for anglers targeting rainbow and brown trout, with the fishing season running from late September through late May. A 4WD vehicle is recommended for visiting the area.
