New
Inlet and Outlet Structure for the Ngak Indau Wetland
The Ngak
Indau Wetland has recently seen a significant upgrade of its outlet
structure due to funding received from the South Australian
Murray-Darling Basin Natural Resources Management Board. A new inlet
structure was also installed by SA Water through a Living Murray grant
to increase water flow and improve fish passage.
During the 2009 filling of the wetland the existing outlet
structure was undermined thus destroying its ability to hold
water within the wetland. A new outlet structure was required to enable
the floodplain vegetation surrounding the wetland to be flooded at pool
level.
The new outlet structure was completed
in June 2010, and has increased the area of inundation from 10Ha
to 21.4Ha when environmental water becomes available. The long term
benefits of the new outlet structure for the wetland includes:
- Improve
the health of existing riparian and aquatic vegetation
- Provide conditions favourable for regeneration
- Improve the quality of the surface water when inundated
- Provide conditions favourable for waterbirds, native fish and
amphibians

'A Day on
the Kat'
‘A
Day on the Kat’ was held on 16 May 2010 to promote and educate
the community on Katarapko as a priority floodplain for environmental
flows and rehabilitation works for native fish. Canoe and walking
trails commenced at the junction of the Splash and Katarapko Creek with
participants enjoying a cooked breakfast, provided by the Rotary Club
of Berri, around a warm campfire before their departure.
Over 100 canoeists and walkers followed Katarapko Creek downstream,
enjoying the peaceful surrounds and nature calls of the Kat. Groups
stopped at four stations along the way and learned about native fish in
the Kat and how they are monitored. Participants were encouraged to
look and explore river bugs and crustaceans through microscopes and
specimen trays. A highlight for some was a close encounter with a
Murray-Darling Carpet Python which are local to the area, and getting
their hands messy making catfish nests.
