About the document
The Commonwealth Environmental Water Office contracted the NSW Department of Primary Industries – Fisheries to undertake mapping of important fish habitat along the Dumaresq River.
The project mapped 193 km of habitat along the along Dumaresq River between the Pike Creek junction downstream to its confluence with the Macintyre River.
Information collected as part of the habitat mapping project was used to identify relationships between river flow height and habitat availability for native fish. Commence to inundate heights were recorded and analysed for large woody habitat, rootballs, bank overhangs, in-channel benches, and entry points to connected wetlands to identify the river flows required to inundate these features.
The report provides important ecological information that has informed the adaptive management of Commonwealth environmental water, including recent watering actions in the northern Basin. For further information on these actions refer to:
