Coorong District Council response measures to Novel Coronavirus (COVID-19)

The Coronavirus (COVID-19) pandemic is a global crisis, and our Council has a key role to play in limiting the spread and impact of it.

Our leaders are staying up to date on the latest advice from the State and Federal Governments, and relevant Government health agencies.

Residents who are experiencing financial hardship may seek assistance from Coorong District Council by entering into a long-term payment arrangement. Information is available on our Financial Hardship page.

Update - 25 May 2020

The SA Government have released their Roadmap for Easing Covid-19 Restrictions.

Most Coorong District Council services have now resumed:

  • All playgrounds, parks (incl. dog parks and gardens) have been re-opened to the public.
  • All community toilets have been re-opened.
  • All halls can now open and community groups will be able to book facilities (groups are encouraged to contact Council to work through arrangements).
  • The Coonalpyn Caravan Park and Narrung Campground are now open to the public (including public toilet facilities).
  • Sporting facilities can open in accordance with the new measures in place.
  • Public library services:
    • Tailem Bend, Tintinara, Coonalpyn and Coomandook Community Libraries are still closed to the public, however all are offering a 'phone and collect service'.
    • Meningie Community Library will be opening to the public from 3:45pm - 4:30pm Monday to Friday, and from 10am - 1pm on Saturdays.
  • Tailem Rail Museum, Coorong Gallery and the Meningie Information Hub will be assessed in preparation for Council's executive team to make a decision on re-opening from 8 June 2020.

All Council facilities are receiving regular cleaning to ensure facilities are up to standard – however if you come across anything that requires attention please contact Council on 1300 785 277 so that we can attend to it.

Signs will be in place to remind users of their obligations to social distance. Everyone can play their part in slowing the spread of COVID-19 by practicing good hygiene, using hand sanitiser and wiping down equipment and surfaces before and after use.

Dryland Salinity

Dryland Salinity

On this page you will find Dryland Salinity information covering;

- Background - the history of dryland salinity across the Upper South East

- Useful links to other web sites such as; Saltland Pastures SA Manual, Water Connect – Groundwater Data, and more….

Background

A huge amount of salt is stored in the subsurface soils underlying parts of the Coorong and Tatiara. Historically this salt was accumulated when the area was originally covered with seawater. In the Mallee highland zone the salt is held at depth while on the Coastal plains it is much closer to the surface. A dryland salinity problem emerges when the salts are mobilised and carried upwards by a rising water table and surface evaporation.

Originally the deep rooted native vegetation cover kept the watertables at depth by providing a balance between rainfall recharge and evapo-transpiration. However with clearance of scrub lands and their replacement with shallow rooted annual crops and pastures, this balance is disrupted and more rainfall reached the watertable causing a general rise bringing the dissolved salts closer to the surface.

The Water Cycle and Dryland Salinity

The Water Cycle and Dryland Salinity

The widespread sowing of lucerne in the ranges when the land was first cleared assisted in keeping watertables in check, however the pasture aphid invasions of the late 1970’s and the dramatic loss of susceptible lucerne stands at that time led to a general watertable rise and a rapid spread of dryland salinity in adjacent low lying areas.

Where the summer – autumn watertable is within two metres of the soil surface the effects of dryland salinity are likely to be most severe. Groundwater is drawn up through the soil profile by capillary action, eventually evaporating as it reaches the surface, leaving the salts at or near the topsoil root zone.

The Upper South East Dryland Salinity and Flood Management Program was designed to remove excess surface water and saline groundwater from the salty flats on the Coastal plains and direct it into the Coorong or out to sea via the Blackford Drain. However the lateral effects of the drains in reducing adjacent dryland salinity on pasture land are still being assessed due to a run of dry years.

Within the Coorong District, 57,000ha (8-9%) of agricultural land was affected by dryland salinity (2000). If trends continue another 70 000 ha (10-11% ) will be at risk by 2020. Since that time, the Coorong District has had a long run of dry years. The Coorong Tatiara Local Action Plan has been involved in recharge reduction works across 14-18% of the District. Groundwater levels have mainly stabilised or dropped, although water tables are still rising in some areas. Over recent years landholders and agronomists report new dryland salinity affected, due in part to heavy summer rainfall events.

Salt Land Pastures South Australia Manual

This Salt Land Pastures South Australia Manual provides information about saltland pastures and fodder shrubs, and is targeted at land managers, agronomists and extension workers. Information is based on trial and demonstration work carried out across South Australia, and much of it from within our region.

Saltland Pastures South Australia Manual

After looking through this manual land managers should be able to;

  • Better understand the potential of saltland pastures and fodder shrubs
  • Recognise suitable pasture plants for different classes of saltland
  • Use tools for evaluating economic performance
  • Better understanding of whether saltland productions systems are likely to be a success for them
  • Characterise their saltland
  • Appreciate other site factors that influence production and profitability
  • Access tried and tested establishment and management techniques
  • Appreciate the payoffs and pitfalls experienced by other farmers working with saltland

Water Connect - Groundwater Data Click here to find information on wells and groundwater in South Australia using this interactive online map.

https://www.waterconnect.sa.gov.au/Systems/GD/Pages/Default.aspx

Groundwater Data has information on over 240,000 registered wells across South Australia. It is easy to browse for wells using the Google Maps platform, including satellite imagery. Other search options include: by property, well construction permit number, and GPS co-ordinates.

Trends in groundwater and salinity levels are monitored over time using data from both private and government wells, assisting in groundwater resource management.

DEWNR Principal Hydrogeologist Steve Barnett has provided us with the following document explaining step by step how to successfully access groundwater data from this website.

He has also provided step by step instructions for accessing up to date data for the Coomandook Landcare Observation Wells.
