June 2024 Fair Fair Good Fair Fair

Bushland revegetation continues to improve the banks and verge.

June 2022 Fair Good Fair Fair Fair
June 2021 Good Fair Good Fair Fair

Overstorey predominantly native (revegetated) provides extensive cover and shading across channel but understorey is very weedy.  Frequent large clumps of instream vegetation.   Sand and gravel substrate with introduced large boulders creating riffles and controlling erosion.  Banks largely protected but some erosion on northern bank.  High flow event within last week increased depth to ~0.5m which has flushed leaf litter from low banks.

June 2019 Good Fair Good Good Fair

In stream vegetation patchy but reasonably extensive.  Active erosion and deposition occurring along the site area.  Verge and bank vegetation still extensive and of reasonably good quality. 

June 2018 Fair Fair Fair Good Good

Still rather weedy banks, but native verge vegetation maturing and now provides good cover.  In stream vegetation improved.  Still some spot erosion evident along banks, but not severe.

July 2017 Fair Fair Fair Fair Fair

23 July 2017:  Erosion is less active, bare sand beds are still present, native verge vegetation is improving but the banks are weedy.

June 2016 Poor Fair Poor Good Fair
Erosion still very active - sand banks in bed smothering in-stream vegetation which is very patchy. Very weedy verges.
June 2015 Good Fair Poor Fair Fair
21 June 2015: Observation site is now 100 m downstream of the earlier site, now close to our water sampling site. There has been unsightly and possibly serious pollution in the Glen Waverley Drain (Crosby arm, site 1b). All underwater surfaces (rocks, soil, vegetation) are coated with a soft clinging pale brown substance, with a consistency like lint and flour paste mixed, with a slight fatty odour. This extends from emergence from pipes at Waverley Rd, downstream to the first wetlands pond at Blackburn Rd. Otherwise, assessment is similar to the previous site in 2014.
August 2014 Fair Fair Fair Good Good
Still very limited in-stream vegetation. Native revegetation on the banks and verges is good. Active bank erosion is happening.
July 2013 Fair Fair Fair Fair Good
Very little in-stream vegetation. Some tradescantia and onion weed on the banks. Native revegetation on the banks and verges is good.
August 2012 Fair Fair Fair Fair Good
26 Aug 2012: Still very poor in stream vegetation due to 2010 pollution and sediment deposits (probably from upstream bank erosion and erosion of crushed rock pathways). Widespread weeds (tradescantia and panic veldt grass) on both verges.
August 2011 Poor Fair Poor Fair Good
bank vegetation was rated a 5.
