- DO% saturation incorrect as Electrical Conductivity of water was not measured (the EC meter died - tried new batteries but didn't work). Have entered a random value to avoid error on submitting the data.

- Ammonium score degraded due to sewage spill extending from Billabong bridge into the lake.

- Monthly test delayed due to sewer spill - March - April

- Water very discoloured - almost black, smelly and still due to the sewage spill.

- No water in Vegemite Creek (one of the feeder creeks that enters the lake at Pobblebonk point)

- 2 female chestnut teals, 1 coot
