This model describes how nutrient, plant growth and clarity factors in Lake Tarawera interact and how these factors affect the abundance of waikoura in this lake ecosystem.
Lake Tarawera is a deep, temperature stratified volcanic lake used for recreational swimming, fishing and mahinga kai, and is surrounded by forestry with some housing on the south west side. Current local concerns are on sewerage outfall from septic tanks which should be reduced thru new wastewater infrastructure upgrades underway
Agricultural land use, Waste and Storm water are the main nutrient inputs into Lake Rotorua.
