Outlet of the 16.6 km long Murrumbidgee - Eucumbene tunnel running from
Tantangara Dam to Lake Eucumbene. Up to 19 cumecs flows out of the 3m diameter tunnel and along the flume. Large concrete blocks act as energy dissipators which agitate the water mixing in air to slow the water flow. They become visible during drought conditions,during tunnel outages or when water needs to be held in
Tantangara Dam. At such times the water in the flume has only a small flow due to seepage in the tunnel. Algae are able to grow a metre or so in length as there is no turbulence to break their strands.
By 2018 nearly 60 years of erosion has gouged out the
rock and soil along the 700 m channel leading into the Eucumbene River. The 10 metre high banks are collapsing and the watercourse is in need of remediation with rip rap to stabilise the channel.
