After 150 years of research, one might assume that we have a fairly complete picture of the invertebrate communities in New Zealand streams and rivers. However new research suggests that high altitude streams have distinctly different, poorly-known, biological communities.
River flows - April to June 2012
The three month picture (on the right) shows the extreme dryness across most of the country, and the after effect of a wet April over East Cape and Hawkes Bay.
River temperatures April to June
Autumn river water temperatures were mostly in the range 8 to 16oC and tended to be slightly higher in the north and at lower altitude.
Observed flow Jan-Mar 2012:
River flows were far above normal in most of the North Island and in Central Otago, and far below normal on the West Coast of the South Island.
