Lake Tutira is a body of water in northeastern Hawke's Bay, New Zealand.
Much of the area was surveyed by Herbert Guthrie-Smith, who farmed 60,000 acres (240 km²) surrounding the lake. Guthrie-Smith, a naturalist, published Tutira: the story of a New Zealand sheep station in 1921. Today, a camp is run at the site of his homestead.
The lake contains a high-resolution record of the sedimentation since its formation about 6,500 years ago.[1] 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 sedimentatary signal; Cyclone Bola being a particularly important recent example.[2][3]
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.[4]
