Late autumn/winter watering actions To create recession flows at the end of the unregulated flows. To reinstate part of the continuous flows that would have occurred prior to river regulation during winter-spring. To improve links with other parts of the river system (WUM 10054-07, 10054-08) What did Commonwealth environmental water contribute to temperature regimes? NA- this was not a target of these flows CEW was delivered to all zones, making water quality impacts of the flow difficult to assess. However, the small delivery of CEW to zone 2 supported what would be an otherwise extremely low flow in this zone and is likely to have supported DO concentrations in this zone. What did Commonwealth environmental water contribute to dissolved oxygen concentrations? CEW may have assisted with maintenance of DO in Zone 2 where flow would have otherwise been extremely low.
