Water Security State of Play: NSW Northern Rivers December 2020

 

As of 26 November 2020 an estimated 80.5 per cent of the NSW Northern Rivers region was not in drought. However, 1 per cent of the region was in full-blown drought, another 10 per cent drought affected and 8.2 per cent recovering, according to the NSW Dept. of Primary Industries.


By 2 December urban water supply in the region was coping but beginning to fall markedly. 


Clarence Valley Council sources its urban water from the Shannon Creek Dam and the Nymboida River Weir. Currently Shannon Creek Dam is at 84 per cent capacity and water flow at Nymboida Weir is well below safe extraction level. Level One water restrictions are in place across the valley.


Ballina Shire Council, Byron Shire Council, Lismore City Council and Richmond Valley Council all principally source their urban water through Rous County Council. The two dams in this cluster are currently at 90 per cent (Rocky Creek) and 89 per cent (Emigrant Creek). With Mullumbimby in Byron Shire sourcing its water from council’s own Laverty’s Weir. Everyday water restrictions apply in all four local government area ie., recommended water use of 160 litres per person per day.


Kyogle Shire Council draws its urban water from a weir on the Richmond River, a natural weir pool on Tooloom Creek and the small Petrochilos Dam with under gravel pump extraction from nearby Peacock Creek. Level One water restrictions are in place across the shire.


Toonumbar embankment dam on Iron Pot Creek about 30 kilometres west of Kyogle was at 55.7 percent of capacity on 30 November 2020.


Tweed Shire Council draws its urban water from the freshwater section of the Tweed River at Bray Park Weir, Clarrie Hall Dam and the weir pool on Tyalgum Creek (Oxley River). Due to low rainfall the Tyalgum district is now on Level Two water restrictions.


The Australian Bureau of Meteorology rainfall and temperature predictions for January to March 2021 show that though the rest of summer may be hot across much of the Northern Rivers region there is reason to hope that rainfall will be adequate to meet our needs.
