The Karoonda region is a low-rainfall region and offers challenges to both agriculture and the environment. This information is gratefully provided by the Murray Mallee Local Action Planning Association.
Groundwater quality is good in the Pinnaroo-Lameroo area but declines to the north and west, posing salinity problems for the Murray River. Good quality groundwater is currently being used for irrigated horticulture as well as stock watering.
Rainfall is relatively low ranging from 250mm per annum in the north and 400mm per annum in the south. Drought can be expected 1 in 5 years in the northern areas. Frosts can occur from July to September. Strong winds from the SW to NW can feature from July on and hot northerlies can occur from Sept through summer. Average daily maximum temperatures range from mid to high teens °Celsius in winter to low thirties °Celsius in summer.
Soils are generally sandy and, when left bare, are highly susceptible to wind erosion. Water repellent (“non- wetting”) soils occur in the south.
