Lake Tutira is located 30 km north of Napier and is an important recreational resource for the Hawke’s Bay region. The lake has an area of 1.74 km2, mean depth of 21 m and maximum depth of 42 m. It has a recent history of poor water quality, and over 2011 and 2012 there were severe blooms of blue–green algae (cyanobacteria), which detracted from the ecological and aesthetic value of the lake, and impacted on its suitability for recreational use.
We analysed the recently–available (2009–2012) monitoring data for Lake Tutira, which included periods of regular (c. monthly) water quality monitoring measurements, as well as data from an automated high–frequency monitoring buoy. Poor water quality in Lake Tutira is not a recent problem and TLI values in the 1960s and 1970s were higher than those for the analysis period. High–frequency buoy data demonstrated that high–intensity rainfall events produced rapid increases in water level and increased turbidity. Increases in chlorophyll fluorescence a few days after major rainfall events indicate that rainfall events may also stimulate increases in phytoplankton biomass in the lake via increased nutrient inputs associated with stormflows.

In 1998 Hawke's Bay Regional Council bought the Guthrie-Smith Trust's land on the eastern side of the lake. The Council then set out to illustrate to the community how this type of land can best be developed to minimise soil and nutrient loss and to develop a great recreational asset in the form of Tūtira Country Park.
