Lake Rotorua is 8 kilometres (5.0 mi) due west of Kaikōura in the Canterbury region of the South Island of New Zealand.[1]
A 2010 report showed that Lake Rotorua had the second highest trophic level index, an indication of pollutant levels, of all the lakes that were measured.[2] Topdressing, shags and willow trees contributed to the high levels of pollution. 29 species of green algae were identified.[3] The lake was fenced to keep cattle away from it and there were conflicting reports on pollution levels in 2022.[4][5] A wildlife reserve surrounds the lake, with birds including riroriro, toutouwai, pīpipi, pīwakawaka, korimako, tītitipounamu, kāruhiruhi, kuruwhengi, tētē, pūtangitangi, pūteketeke, mallard and Canada geese.[6]
The lake was formed by greywacke shingle in the Kahutara River building up to block the mouth of a former tributary.[3]
