Freshwater results
B Noosa Catchment  
  • Streams generally in good condition
  • The largest change since last year was a reduction in scores for the ecosystem processes indicator 
  • Physical/chemical indicator scores remain high
Estuarine results
A- Noosa Estuary  
  • Lower inorganic nutrients in the middle and upper reaches compared to 2006
  • Lower freshwater inputs from the catchment resulting in higher salinity levels upstream compared with 2006
  • Intact seagrass meadows and natural riparian habitat throughout much of the estuary
