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 initially designed and implemented in 1994

by the Swan River Trust and Department of Water (then Water and Rivers

Commission). The project currently falls under the Department of Parks and Wildlife's

River Protection Strategy and is jointly operated by the Water Science Branch of the

Department of Water and the Department of Parks and Wildlife.

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 twenty seven sites (All sixteen from the SWANCATCH project and eleven of

sixteen from the SCWQIP 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 five

of the sixteen SCWQIP sites have not been presented in graphs because sampling

only began in April 2011, so there is not five years of complete data for the

background box plots. 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 second quarterly report for 2016 and presents 2016 data from

January to June over background data from 2011 to 2015. 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 (2016) is presented in tables showing monthly minimum and

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

Data, collected from all 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.

Rainfall during autumn 2016 was mostly above average for the Perth Metropolitan

region, with totals ranging from 137.2 mm at Garden Island to 310.0 mm at Bickley in

the hills. Perth recorded a total of 197.0 mm, which was just above the autumn

average of 180.2 mm, and the wettest autumn for three years. Mean maximum

temperatures in autumn were 0.4 °C to 1.3 °C below average in the Perth

metropolitan area, while mean minimum temperatures were above average (BOM

climate summary).

All monitored catchments resumed flow by the beginning of June which is unusually

early. The combination of summer rain events and early onset of winter like rains

resulted in the Avon/Upper Swan site (SWN5) seeing two cessations and

resumptions of flow during summer 2015-16, which is also very unusual.
