The Hastings River Floodplain Risk Management Plan (HRFRMP) 2013 identified the need for additional streamflow and rainfall gauges to be incorporated into the existing network to improve flood predictions for the Hastings River catchment.
Currently there is a lack of flood level and rainfall gauges within the Hastings River catchment and the HRFRMP recommended gauges be installed at various locations within the river system to improve flood predictions.
$50,000.00 in grant funding was received in November 2017 from the NSW Government under the Floodplain Management Program for the installation of additional gauges within the Hastings River catchment.
Council engaged Manly Hydraulics Lab (MHL) to identify gauge priority, type and locations which will provide the greatest benefit when considering:
- BoM’s predictive modelling
- flood warning systems
- future flood studies / models
- calibrating flood models.
Preliminary investigations were undertaken which identified potential locations for the installation of additional gauges and where improvements can be made to existing gauges.
Council and MHL successfully installed a new river level and rainfall gauge at Mundays Lane, on the Maria River Catchments. The new flood gauge has been in operation since late 2019 and now provides near real-time water level and rainfall data. This information will be primarily be utilised by the Bureau of Meteorology (BoM) to improve flood predictions for the Maria River catchment, however the collected data will also contribute to future flood studies undertaken by Council.
Council also worked with the SES on this project to ensure that the project will result in a good outcome from a flood management and response perspective.
Live data from this gauge can be viewed at any time via the MHL website: https://www.mhl.nsw.gov.au/Station-2074127
Council will continue to investigate each proposed gauge site in further detail and hopes to install the additional gauges via a staged approach over coming years.
