Lake Rotoiti, Lake in Tasman District, New Zealand

Lake Rotoiti is a lake in Tasman District, New Zealand, set at an elevation of about 2,034 feet (620 m). It lies in a valley surrounded by hills, with clear water and a shoreline that mixes sandy beaches and rocky sections.

The lake was formed by glacial action during the last ice age, which carved the valley and left a basin that filled with water. In the 19th century, European settlers began farming in the area, and the lake became a water source for nearby farms.

The name Rotoiti comes from Māori, where 'roto' means lake and 'iti' means small, and locals often use the lake for fishing and boating. On calm days, you can see families picnicking on the shore and small boats heading out from the jetty.

The lake is best reached by car, and the roads around it are narrow in places, so drive with care. Walking tracks start near the main access points, and it helps to bring water and wear shoes with good grip.

The lake is known for its population of longfin eels, which can grow very old and are often seen by divers. These eels are a taonga, or treasure, to local Māori, and catching them is regulated.
