This report has been written in response to the Department of Primary Industries and Fisheries request for an overview of the prospects for horticultural water supply in the area between Katherine Town and Carbeen Park Farm located approximately 40km downstream on the Katherine River. The CCNT map 'Katherine Levee - Horticultural Potential' has distinguished land units in the region by their suitability to spray and trickle irrigation. At present, water for horticultural use is largely supplied by the Katherine River and from the site bores. The extent to which the river can be further utilised as a source of water is described. Groundwater supplies are investigated as well as alternative surface water options.
