The state government is investigating whether recreational fishing should be allowed at Cataract Dam.
The reservoir, between Wollongong and Appin, is currently off limits to fishers, boaters and swimmers because it supplies water to the Camden, Campbelltown and Wollondilly council areas.
However, those restrictions could soon be lifted, as the NSW Department of Primary Industries undertakes a risk assessment of dams in the Sydney catchment.
A spokeswoman for NSW Primary Industries Minister Niall Blair said a working group, of DPI representatives and a Recreational Fishing NSW Advisory Council member, was exploring the dam’s potential.
“The risk assessment is an investigative project and no decision on permitting recreational fishing access to Sydney dams has been made,” she said.
Cataract Dam has a range of fish species, including those moved there from west of the divide like Murray cod and Macquarie perch.
The move to open Cataract Dam for fishing would bring the reservoir in line with a number of dams in regional NSW.
