The unnamed tributaries on this site are generally small,
clear running low energy brooks with silty beds, however with increased rainfall the
suspended solids level can rise quite quickly as silt is stirred up from the beds and
edges of the streams and is entrained in the flow. Overall the level of suspended
solids indicates good water quality in the stream system.
Apart from a slight comparative spike in conductivity levels in the results for June
2008 in the downstream sites, the
expired on 1 June
2011, but remained in force while application for a new consent was being processed.
There were eight conditions associated with this consent which set out how the
consent shall be operated and managed.
Condition 1 was a review provision.

Condition 2 set out the terms of use of the consent during heavy rainfall only.
Condition 3 set limits on the components of the discharge.
Conditions 4 and 5 placed limits on the concentration of
properties are rural in character. The
nearest towns are Stratford which is 10 km to the south east and Inglewood which is 12 km to the north.
The predominant soil type has been identified as gravelly sand, and vegetation growth transitions from
native forest at the edge of the national park to pasture. The average annual rainfall for the site is 1,942 mm
based on the Stratford meteorological station.

Taranaki District Council, which operates the Eltham municipal wastewater
treatment system located to the east of Eltham in the Mangawhero catchment, holds a
resource consent to allow it to discharge treated wastewater to the Mangawhero Stream
under high rainfall conditions only. The consent for the discharge of emissions into the air
expired in mid 2011 and is no longer considered necessary. This report for the period July
