energy wave environment, lack of stable habitat and periodic sand inundation.
Sand deposition has been shown to have a profound effect on intertidal communities in
Taranaki. The reef sites at Mangati and Greenwood Road (north Taranaki) were particularly
prone to periodic sand inundation. Years of high sand accumulation at these sites resulted in
lowered species richness and diversity. Trend

Most of the inflow (85%) to Lake Mangamahoe is sourced from a diversion on the Waiwhakaiho
River that comprises an intake and tunnel on the left bank of the river. The balance of the lake inflow
(15%) is derived from natural tributaries to the lake, principally the Mangamahoe Stream and Kent
Road Stream. Water is returned to the Waiwhakaiho River via the MGR power station at Hydro
