West bank vegetation growing well. Some new dianella plants at top of west bank. In-stream vegetation degraded/gone.
July 2022	Fair	Fair	Good	Fair	Good
Dense, maturing vegetation on west bank (native vegetation) of very good quality. A lot of weeds along both banks, including ivy. Some non-native grasses. Some localised erpsion on west bank. Considerable variation in stream width ranging from 0.5-3 m.
August 2021	Fair	Fair	Good	Good	Good
Weedy ground cover. One area cleared, likely sprayed prior to replanting. Good native overstorey.
July 2019	Fair	Fair	Good	Good	Good
Matured vegetation growing tall on east bank may be due to absence of willows. New native plants on the west bank.
July 2018	Fair	Fair	Good	Fair	Fair
22/7/2018: Recent plantings - 2000 plants along east verge. Native vegetation recovering after removal of willows.
June 2017	Fair	Fair	Fair	Fair	Fair
Willows all removed (stags left in place), reducing overhead cover. Banks appear to be unstable. No revegetation as yet under the willows. Some regeneration occurring. In-stream vegetaion increased.
July 2016	Fair	Fair	Fair	Good	Good
Verge replanting is ongoing, resulting in good habitat. The willows are dropping old limbs over and into the creek.
July 2015	Fair	Good	Fair	Fair	Fair
19 July 2015: Similar to 2014. Some local erosion is occurring opposite a willow which is impeding the flow. Revegetation is progressing. Vegetation in an overflow side channel is good.
June 2014	Fair	Fair	Fair	Fair	Fair
Similar to 2013. Vegetation hanging over the banks has not yet recovered from weed clearance and lowering of the pool.
June 2013	Fair	Fair	Fair	Fair	Fair
The banks of the pool remain sparsely vegetated. Some spot erosion. The sloping banks and verges downstream have improved vegetation.
July 2012	Fair	Fair	Fair	Fair	Good
