River Health Monitoring

Aquatic Health Unit

Julia Fortune, Julia Schult

overview
Overview
  • Introduction
  • New NRETAS funding
  • Nutrient monitoring and research
  • Daly River Monitoring Status Report
  • Discussion
drmag suggested approach
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
current work
Current Work

NRETAS funding $60k:

  • Nutrient Monitoring
  • Nutrient Limitation Research
  • Daly River Monitoring Status Report
nutrient monitoring and research why nutrients
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
proposed nutrient monitoring dry season 2011
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
nutrient limitation research
Nutrient Limitation Research
  • Limited information on nutrient limitation and likely effects of nutrient increases
  • Nutrient limitation research in collaboration with TRaCK

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
status report
Status Report
  • Style similar toDarwin Harbour Report Cards
status report example only pressure monitoring
Status Report (Example only)Pressure Monitoring
  • Land Use
  • Clearing
  • Water extraction/bores
  • Fire frequency
  • Flows/gauge stations
  • Mining
slide11

Status Report (Example only)Stressor Monitoring

  • Overview of current stressor monitoring
  • Historical WQ monitoring (2005-2010)
slide12

Status Report (Example only)Biological Monitoring

  • Fish monitoring (DoR)
    • E.g. catch per unit effort data
  • Macroinvertebrates (DoR)
    • E.g. disused mine monitoring
status report outcomes
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
