Ivy covers the west bank at the upstream end of the site.  Narrow verge coverage of native trees and bushes, flanked by paths and mown grass.

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

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 Fair Fair Fair Fair Poor

Very little in-stream vegetation, and continued deposition of sand and gravel along the site-area stream bed.  Erosion appears more extensive than last year. 

June 2018 Poor Fair Fair Fair Poor

Erosion along North bank has increased, vegetation cover along N bank and verge affected by deposits of sand/gravel. Verge vegetation still very weedy.

July 2017 Fair Fair Fair Fair Fair

23 July 2017:  There is still very little in-stream vegetation. Verge vegetation very weedy (Tradescantia etc). Spot erosion still apparent.

June 2016 Fair Fair Fair Good Fair
In stream vegetation has been largely removed by dredging - slowly returning. Verge vegetation very weedy (Tradescantia etc). Spot erosion still apparent.
June 2015 Fair Fair Good Fair Fair
21 June 2015: Little change from 2014. The bridge approaches have been concreted to avoid washouts of the previous crushed granite surface.
August 2014 Good Fair Fair Good Fair
Exotic weeds are rampant on the west bank / verge. In-stream vegetation is patchy but reasonably good.
July 2013 Fair Fair Fair Fair Fair
Banks have been cleared of some weeds, exposing some local erosion. Sandy sediment is accumulating in the stream bed.
August 2012 Fair Good Fair Good Fair
26 Aug 2012: Bank erosion has increased. Weeds have increased (tradescantia). In stream sediment (probably eroded from crushed rock pathways) is inhibiting in stream vegetation in some places
