the Sweetwater spring complex, although spring type E, F or G are likely conceptual types. Spring complex overview Sweetwater is located 76 kilometres north-north-west of the town of Bourke and 16.6 kilometres south-west of the town of Enngonia, northern New South Wales. The complex consists of one inactive spring—although there are some soaks and vegetation present (Figure 69). The complex has been given a conservation ranking of 2. The spring wetland area covers about 13 square metres. A summary of basic hydrogeological information available is in Table 147. Table 148 sets out the location and elevation of the spring.
