Victoria River Region
The aim of this study is to map, describe and evaluate the region's water resources. The project was started in 1993 at the request of the Victoria River District Conservation Association (YRDCA) and it was funded jointly by Landcare, the NT Government and the purpose is to provide pastoralists and communities with water resource information that will assist with property planning.

TABLE 1 Average climatic figures. GEOLOGY Rock type and geological structure are some of the main factors influencing groundwater occurrence and the location of springs. The suitability of an area for dams is also partly determined by these. The distribution of the major geological units are sho"VTI in Figure 3 and their relationships \vith each other with depth are sho'im on the cross-section in Figure 4. The oldest rocks in the district are sandstones, siltstones and dolomites of Pre-Cambrian age (older than 545 million years). These outcrop in the central areas, with resistant sandstones forming ranges and softer rocks such as siltstones forming the valleys. The sedimentary rocks are in alternating layers that have been tilted at low angles, normally less than five degrees. Extensive jointing and some faulting was created when the rocks were folded. 3
