IN THE DEGREE SQUARE

The Weir River begins in the degree square to the east. It flows SW, running parallel to the Macintyre and Barwon until it joins he Barwon near Mungindi, on the Qld-NSW border (in the degree square to the SW)

Many plant and animal species have been introduced to Australia for a variety of reasons. One of the most destructive has been the prickly peas cactus.
At its worst it rendered much valuable agricultural land useless. It is still found in large clumps in parts of the wheat-sheep belt. These specimens were seen at the degree observation point. Renewed efforts are underway to deal with this problem species.

Climate: The closest representative weather station is at Goondiwindi, which is 68 km south-east of the confluence, and has an elevation of 106 m.

The highest temperature recorded was 44.2°C in November 1996, and the lowest was -4.2°C in July 1992. The greatest rainfall recorded in a year was 966.1 mm in 1996, and the lowest was 321.5 mm in 2006. These and other climate statistics for Goondiwindi can be found at: Australian Bureau of Meteorology, http://www.bom.gov.au/climate/averages/tables/cw_041521_All.shtml

Extremes of Nature: Since 1906 there has been one cyclone to pass within 50 km of the degree confluence (1950 Unnamed), and a further 10 have passed within 200 km. Cyclone information for this area and all of Australia can be found at the Australian Bureau of Meteorology website, <http://www.bom.gov.au/cgi-bin/silo/cyclones.cgi>

Extreme heat can also be a potential danger. Records show that Goondiwindi experiences 36 days annually with temperatures over 35°C, although very rarely does it reach 40°C or warmer. Such extreme temperatures can cause heat stroke and death if appropriate measures are not taken such as avoiding strenuous physical effort, keeping as cool as possible and drinking lots of water. Heat waves kill more people in Australia than all other natural hazards combined.

Today:  The population of the degree square at the 2011 national census was 1997.
