Much of the area was surveyed by Herbert Guthrie-Smith, who farmed 60,000 acres (240 km²) surrounding the lake.[2] Guthrie-Smith, a naturalist, published the popular Tutira: the story of a New Zealand sheep station in 1921.[3] Today, a camp is run at the site of his homestead.[4]

A small settlement, Tutira, is located near the lake, on State Highway 2 30 kilometres north of Whirinaki.

Sedimentary cores from the lake were used to demonstrate that the landslides mobilising sediments for transport into the lake occur in frequency and magnitude according to a power law.[5]

Trout fishing is permitted as a stream flows into its northern reaches. For centuries Māori seasonally lived by Lake Tūtira and you can see the remains of six pa sites. The Tutira Walkway, ascends to the Table Mountain trig station for stunning views over Hawke's Bay and takes about five hours to complete.

The lake suffers from periodic algal blooms.[6]

Geological history

The lake contains a high-resolution record of the sedimentation since its formation about 6,500 years ago.[7] It has a small catchment area, whose dominant erosion mechanism is landsliding; as a result of this, infrequent, large storms account for the bulk of the sedimentary depositional volume; Cyclone Bola is a particularly important recent example.[8][9]

Education

Tutira School is a co-educational state primary school,[10][11] with a roll of 29 as of March 2020.[12][13]

gollark: English is highly redundant. You should be able to extract meaning from terse communications.
gollark: Lack of coherent response to it interpreted as bees at the femtoscale.
gollark: I see.
gollark: Well, I was timed out for 10 minutes for whatever reason, and people generally don't press buttons like that by accident.
gollark: There are obviously some non-voting ways to influence politics, but those are generally more costly/annoying, so the situation is probably not much better.
