Ambient and Flood Event Water Quality Monitoring

Monitoring of river water quality in the Normanby catchment has been conducted by CYMAG Environmental (CYMAG), the Australian Institute of Marine Science (AIMS), the Qld State Government and Griffith University.

  • CYMAG conducted monthly monitoring of pH, temperature, conductivity, salinity, dissolved oxygen, total and dissolved nutrients and chlorophyll-a at 10 freshwater and estuary locations across the catchment between 2006- 2010. Metals, herbicides, and hydrocarbon concentrations in water and sediments were also analysed (Howley, 2010).
  • AIMS monitored turbidity, nutrient and total suspended sediments (TSS) at Kalpowar Crossing (50 km upstream from the mouth) between 1997-2000.
  • The Qld Department of Environment, Resources and Mines (DERM) has conducted irregular monitoring of water quality at gauging stations across the catchment since 1968.
  • The Queensland Department of Science, Information, Technology, Innovation and the Arts (DSITIA) has monitored suspended sediments and nutrient concentrations at Kalpowar Crossing since 2006 as part of the Great Barrier Reef Catchment Monitoring (GBR I5) program.
  • Additional monitoring of nutrient and suspended sediment concentrations (SSC) during flood events occurred across the catchment between 2011 - 2013 (Howley/ Griffith University unpublished data).

These water quality datasets have been used to assess water quality conditions for the upper and lower Laura River, East and West Normanby tributaries, Normanby River at Lakefield National Park (including Kalpowar Crossing) and the Normanby estuary. The water quality conditions for each region  (based on the 20th, 50th and 80th percentile ranges during dry season baseflow, wet season baseflow and wet season flood events) are presented in the tables below.

The complete results of the CYMAG Normanby River water quality monitoring project (Howley 2010) as well as the Annan, Endeavour and Jeannie Rivers water quality monitoring project (Howley et al 2012) can also be downloaded from this site.
