Noosa River environmental values and water quality objectives

Water area/type Management Water quality objectives to protect aquatic ecosystem EV
(refer Plan intent (level of
WQ1401) protection)
However, in areas where seagrass is intact, it is more important to
maintain existing water quality. Therefore the WQOs are:
local total suspended solids, turbidity, secchi and light
attenuation is maintained; and
local seagrass distribution and composition is maintained, as
measured by:
• extent of seagrass;
• species diversity; and
• seagrass depth limit.
Marine/estuarine Aquatic Protect or restore riparian areas. Refer section 3.1.3 – riparian area
