Small fish, big headache for Snowy Hydro scientists

Redfin survive in Talbingo Reservoir, but have been seen infrequently in Tantangara Dam (image: Martin Auldist).

SNOWY Hydro is investing tens of thousands of dollars to prevent redfin escaping into some of New South Wales’ top trout fishing lakes.

According to an article in The Land, the unlikely headache for Snowy 2.0 hydro scheme scientists has emerged because the class one NSW pest fish survives in Talbingo Reservoir, while it has only ever been  seen infrequently in Tantangara Dam. 

The Snowy 2.0 scheme plans to link the two reservoirs via a 27 km tunnel that includes a massive underground electricity generation plant. Unbelievably at this stage it may be possible for the despised redfin or its eggs to pass through the large turbines when water is pumped back up from Talbingo to Tantangara.

Snowy Hydro is using scientists to try and find ways of preventing the redfin from being flushed up the system. In the next week a science body will also be contracted to help solve the dilemma.
