Recent rain refreshed the water in the wetlands and the general appearance is good (slow flows bypass the wetlands because of pit blockages, 12 mm events usually refresh the ponds).
Stream flows are slow. Most of the water quality results are Good. However the phosphate and conductivity results from the Crosby Arm are poor.
Habitat ratings for all the sites are Fair or Good.
Site 1a (Fiander Arm) is not as good as last year, with respect to instream vegetation and silt deposited in the stream bed.
Site 1b (Crosby Arm) is slightly improved, with respect to in stream vegetation, but silting and bank vegetation are not good (note, the assessment site is downstream of the sections which were severely eroded in the summer storms).
Site 4 (Wetlands, upstream pond) is slightly improved in all respects except silting and erosion.
