Figure 3.2: Hawkesbury-Nepean River monitoring zones 6 Hawkesbury Nepean River Environmental Monitoring Program: Final Technical Report
Long-term monitoring sites A review was conducted of current and historic SCA, Sydney Water, DECC EPA, DWE and DPI Fisheries monitoring sites in the Hawkesbury-Nepean River. From this list, a selection of sites that had long-term ongoing monitoring was identified. Many of these sites are currently monitored as a result of various licences (e.g. Water Management Licences or DECC EPA Pollution Control Licences). Added to this were sites that were currently monitored under the SCA’s Woronora Environmental Flows Project and sites that were not currently monitored but had a relatively long history of sampling and/or were located in strategic sections of the river system. These sites are identified in Table 3.1 and form the core of the Hawkesbury-Nepean Environmental Monitoring Program.
