Not only does Lake Rotorangi store water for power generation but it is also well used for recreation activities. Over 100km of shoreline have been cleared to allow access to the lake for activities such as boating, fishing, water skiing and canoeing.
When boating on the lake there are boat ramps at each of the three access points. Boats can travel the entire length of the lake unimpeded a journey that takes two days in a kayak or 3.5 hours in a houseboat.
There are three access routes, Rawhitiroa Road in Eltham, Tangahoe Valley Road inland from Hawera and Ball Road north of Patea.
At the south end of the lake there is a designated camping area with unlimited tent sites. Toilet and shower facilities are also available.
A licence is required to fish on Lake Rotorangi these can be purchased from Hawera Sportsworld – phone 06 278 5530.
The Rotorangi Hydo Walk can also be found at this end of the lake. The walk takes you over the dam and through the bush. A feature of the walk is the black beech which, when flowering, are unequalled for the bursts of brilliant red flowers. There are a number of seats on the walkway to rest and enjoy the peacefulness of the forest and there is also a lookout which provides a vantage point above the dam.
The walk is one and a half kilometres long and will take about 40 minutes to complete.
