Abstract
Modern Lake Rotomahana was formed during the 1886 eruption of Mt Tarawera. Heat flow measurements made in the bottom sediments using a marine temperature probe indicate a thcrmal area in the half of lake which has a total condrictivc heat flow of MW. The convective heat discharged into the lake, calculated from tlie rate of incrcase in of the lake, is estimated to bc 145 MW. The ratio of conductive to convective heat flow is similar to that measured in thermal areas beneath Lake Rotorua, North Island, New Zealand.
