Lake Rotorua

Second largest lake in the North Island (after Lake Taupo and Lake Wairarapa ago )

The Lake Rotorua is the second largest lake of New Zealand's North Island. It is located in Rotorua District in the Bay of Plenty region north of the center of the island.

The 80- km ² Lake Rotorua is Lake Taupo after and before the Lake Wairarapa is the second largest lake in the North Island of New Zealand. Its average depth is eleven meters, being 26 meters deep at its deepest point. Overall, the lake has an almost circular shape. It is located inside the caldera of a broken years ago, about 140 000 volcano. The collapsed during this eruption magma chamber forms the bed of the lake today. A little further east - more precisely to the active volcano Mount Tarawera around - there are numerous other lakes.

The Lake Rotorua is served by several inflows of fresh water. In this case, perform the opening out of the southern, volcanically active areas in the lake rivers, such as the Utahina, much warmer water than the opening out of the north in the lake, such as the Sport of Kings Springs or Awahou stream. Another major tributary is the Ngongotaha River, which is known for its trout fishing. About the Ohau Channel, the water flows into Lake Rotoiti.

In the eastern part of the lake, near the center, located at Mokoia Iceland rhyolite from an existing island.

Because of the strong volcanic activity in the area around the lake, the sulfur content of the water is above-average. This gives the lake a yellowish- green color.

The southernmost part of the lake, the Sulphur Bay, is a geothermal area and put under protection.
