The monitoring site at Nicholson Road is located in the lower reaches of the Whenuakura River, 10.7km upstream of the coast. This site is in the upper tidal section of the river, upstream of any saline influence.
Water quality is moderate with most aspects within national guidelines although median values, particularly for nutrients and clarity, may not meet guideline values. This is primarily due to the high sediment load carried by this river. Trend data is not yet available for this site due to the shorter monitoring period.
