Preface

The Swan Canning Environmental Monitoring and Reporting project is a long term

monitoring project consisting of regular sampling of the Swan and Canning Rivers

and selected tributaries within their catchments, enabling regular water quality

reporting and annual reporting on estuarine and catchment compliance against long

and short term targets. The project was designed and implemented in 1994 by the

Swan River Trust and Department of Water (then Water and Rivers Commission) as

part of the Swan-Canning Cleanup Program Action Plan. The project currently falls

under the Swan River Trust’s Healthy Rivers Action Plan and is jointly operated by

the Water Science Branch of the Department of Water and the Swan River Trust.

The sampling conducted for this project is captured under the Department of Water

WIN data management project SG-C-SWANCATCH, consisting of fortnightly

sampling of sixteen sites.

In March 2010 a second catchment sampling project was implemented to address

gaps in previous monitoring and to provide data for predictive modelling of the Swan-

Canning Catchment. This project consists of fortnightly sampling of sixteen sites and

falls under the Department of Water project SG-C-SCWQIP (Swan Canning Water

Quality Improvement Plan). Note that this sampling project was initially run from

January 2007 to June 2008 as SG-C-SWANCCI but was closed due to limited

funding.

Some important changes to the SWANCATCH and SCWQIP projects are listed

below:

• Changed from weekly to fortnightly sampling in 2001.

• Changed from specific conductivity (compensated at 25°C) to uncompensated conductivity in October 2001 and back to specific conductivity in September 2006

• Added parameters Dissolved oxygen and pH in September 2006 (changed instrument from WTW to Quanta).

• Added parameters Dissolved organic nitrogen and Total organic carbon in October 2006. Total organic carbon only sampled to July 2008.

• October 2006 Canning River site moved ~500 m downstream from McKenzie Grove to Seaforth for better site access and to align with location of gauging station.

• October 2006 extra Ellen brook site (EBAC) added to regular sampling near confluence with Avon River. Stopped sampling March 2009 due to site access issues. Site location changed to west swan road bridge (SWN9) and sampling restarted March 2010.

• April 2011 SCWQIP Claise Brook site moved from SCCIN5 to CB13.

• May 2011 South Belmont Main Drain site moved ~100 m upstream from SWS11 (Great Eastern Hwy) to SWS13 (Severin Walk, Abernathy Rd) due to tidal influence at the old site (SWS11). The gauging station has also been moved (~750 m upstream to Cleaver Terrace).



• The Wandoo Creek catchment site was moved downstream to WNDCK (August 2011) as the former site, SCCIN4, was almost always dry, even in winter.

• From April 2012 onwards the SCWQIP sites list was modified and now consists of 16 sites (down from 17); four of which are new sites selected after a period of expanded monitoring where 36 sites were monitored for nine months (Aug 2011 to March 2012).

Summary

This Swan-Canning Catchment quarterly data report presents data collected from a

total of fifteen sites from the SWANCATCH project. Data are presented in graphical

and tabular form for ten key analytes; Total Nitrogen, Nitrogen as

ammonia/ammonium, Total oxidised nitrogen, Dissolved organic nitrogen, Total

phosphorus, Soluble reactive phosphorus, Dissolved organic carbon, Total

suspended solids, Dissolved oxygen and Specific conductivity.

At each site the data are presented as a graph showing the previous five years of

data as monthly box plots overlain by the current year monthly medians. Data for the

lower Ellen Brook site (SWN9) and the sixteen SCWQIP sites have not been

presented in graphs because sampling only began in March 2010. Catchment data

are presented over a calendar year (January to December), with quarterly reports

corresponding to the quarters of the year (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) and

each quarterly report adding to the “current year” data already presented.

This data report is the fourth quarterly report for 2014 and presents 2014 data from

January to December over background data from 2009 to 2013. The background

monthly box plots display the median, 25th, 75th, 10th and 90th percentiles where

sufficient data exists. The graphical program used (Sigma Plot) requires a minimum

of 3 data points to calculate 25th and 75th percentiles and a minimum of 9 data points

to calculate 10th and 90th percentiles. Due to the ephemerality of many of the

catchment sites and the fortnightly sampling regime, the background monthly sample

numbers may often be quite low. For clarity the background monthly sample numbers

(n) have been reported on each graph. The limit of reporting was halved when data

was below the limit to allow the data to be graphed.

The current year’s data (2014) is presented in tables showing monthly minimum and

maximum values and the number of samples collected for each analyte.

Data, collected from the sixteen SWANCATCH and sixteen SCWQIP sites, is also

displayed in tabular form near the end of this report with quarterly means and

standard deviations of the ten key analytes displayed for all sites in one comparison

table for each quarter reported.

The final three months of 2014 were drier than average with Perth receiving just

60.8mm, compared to the long term average of 90.1mm, and Perth received no

rainfall at all during December. During this time catchments began to cease flowing

and then dry completely and by the end of 2014 six of the 15 catchments were either

dry or not flowing including the upper Swan at Great Northern Highway.

Hydrographs (daily discharge in megalitres) have also been included for 2014 for

catchments where data was available.
