Afforestation of 250 km2 within the 906 km2 catchment could account for 2.9 m3/s - 5.0 m3/s of the decrease, which was 9% - 14% of the expected flow. This result agrees with the results of small catchment studies.

Recent (1972-1981) annual, summer and winter flows in the Tarawera river were 6.9 m3/s (20%), 7.0 m3/s (22%) and 8.4 m3/s (22%) less than an earlier calibration period (1949-1963). Afforestation of 250 km2 within the 906 km2 catchment could account for 2.9 m3/s - 5.0 m3/s of the decrease, which was 9% - 14% of the expected flow.
