Our Environment

Water Management

We have a summer recreational water quality sampling program to make sure that popular public swimming areas are safe for recreational use. The sampling is conducted by our Environmental Health Officer once a month from December to March.

The results are based on a Microbial standard for primary contact (swimming) as follows.

Good Water Quality GREEN

Enterococci/100ml less than 140

 

Moderate Water Quality YELLOW

Greater than 140 and less than 280 – conduct sanitary survey

 

Poor Water Quality RED

Two consecutive samples greater than 280 – unsuitable for swimming

We started our St Marys Flood Management program following the floods of 2016.  In 2017 we undertook a St Marys Flood Risk Management project with funding from the Natural Disaster Resilience Grants Program through the State Emergency Service (SES).  This project examined the flooding problem in the St Marys township and identified strategies that will reduce the risks to the community and infrastructure.  The community and others such as the SES participated in the project to test flood mitigation options with flood models developed from 2016 flood data. The project also made a start on flood mitigation works identified by the project.

The project produced two reports

  • Flood Risk Investigation Report on the flood models developed and flood risk mapping
  • Flood Risk Management Report, testing mitigation options and recommending flood management strategies.

The flood maps from the Flood Risk Investigation report can be viewed online here.

You can view and download the reports from the links below.  The Flood Risk Investigation report is large and its map sets are provided separately.

St Marys Flood Risk Management Report

 

A Flood Risk Management Plan is being developed to continue the work of reducing the flood risks and building on the flood resilience of the St Marys community.

Flooding and changes to the floodplain of the Lower George River have been of concern to the community, landowners and Council for many years.
In 2006 the Lower George Riverworks Trust was established as a body to manage erosion, sedimentation and flood issues on the lower reaches of the George River near St Helens. Farming and tourism enterprises, public infrastructure and homes are threatened by floods and river changes on the floodplain.
Major bank erosion works were undertaken in 2007 and currently the Council is supporting the trust to identify strategies and works which can be undertaken to reduce the risks and impacts.
