Abstract

A survey of the status of instream biota of Pencil Pine Creek, Cradle Valley, is being
conducted annually to monitor the effects of discharge of wastewater from a new
wastewater treatment plant, collection and discharge system (Figure 1).
This document describes the approach, methods and results of the survey which was
conducted in each of spring (October) 2009 and summer (February) 2010. The survey is
designed to collect data to assess the status and condition of instream biota – benthic
macroinvertebrates and aquatic algae – at sites adjacent to and downstream of the
proposed new discharge point in Pencil Pine Creek (i.e. receiving water sites). Several
reference sites are also sampled to provide reference/control data against which to assess
changes in Pencil Pine Creek.
The data have been collected in five rounds to date – those reported by Davies et al.
(2005, 2007, 2008, 2009) and that reported in this document
