Collie Lower 2 catchment

The Collie Lower 2 catchment is located immediately downstream of Burekup Weir and the Wellington Dam, and these dams regularly release flow into downstream reaches. This section of the Collie River is beyond the tidal influence of the estuary.

The catchment is around 50% cleared, with land uses mostly consisting of plantation timber, grazing of beef cattle and rural lifestyle properties. These land uses contribute a moderate nutrient loading to the river, but measured concentrations are diluted by the cleaner inflows released from Wellington Dam.
