  1. River Health Monitoring Aquatic Health Unit Julia Fortune, Julia Schult

  2. Overview • Introduction • New NRETAS funding • Nutrient monitoring and research • Daly River Monitoring Status Report • Discussion

  3. DRMAG Suggested Approach • Phase 1: • Coordinated reporting of current monitoring (focus on pressures) • Phase 2: • New monitoring by NTG and community • Dependent on extra resources

  4. Current Work NRETAS funding $60k: • Nutrient Monitoring • Nutrient Limitation Research • Daly River Monitoring Status Report

  5. Nutrient Monitoring and ResearchWhy nutrients? • Most likely impact of development: increased nutrients • Modelling shows potential doubling of algal biomass with nutrient addition • Some doubt about accuracy of historical nutrient data

  6. Proposed Nutrient MonitoringDry Season 2011 • Extensive nutrient sampling using new more accurate analysis technique • Determine reference condition and water quality objectives • Provide opportunities for community involvement in sampling

  7. Nutrient Limitation Research • Limited information on nutrient limitation and likely effects of nutrient increases • Nutrient limitation research in collaboration with TRaCK

  8. Status Report • Bring together information from different agencies • Provide template for future reporting • Introduce P-S-R model • Reporting by subcatchment to highlight areas of greatest pressure

  9. Status Report • Style similar toDarwin Harbour Report Cards

  10. Status Report (Example only)Pressure Monitoring • Land Use • Clearing • Water extraction/bores • Fire frequency • Flows/gauge stations • Mining

  11. Status Report (Example only)Stressor Monitoring • Overview of current stressor monitoring • Historical WQ monitoring (2005-2010)

  12. Status Report (Example only)Biological Monitoring • Fish monitoring (DoR) • E.g. catch per unit effort data • Macroinvertebrates (DoR) • E.g. disused mine monitoring

  13. Status Report - Outcomes • Highlight sub-catchments of concern • Show current bias towards pressure monitoring • Highlight gaps in current monitoring • Provide background info for public consultation • Template for future reporting Expected publication Mid 2011
