Explosions will be heard across the Tantangara area as part of excavation work for Snowy 2.0.

Controlled blasts, each expected to last about 20 seconds, will help create the headrace tunnel that will link Tantangara to Talbingo.

Construction company Future Generation said the surface blasts will allow workers to “excavate rock supports for the intake structure on the western foreshore of the [Tantangara] reservoir.”

Explosions will occur from 4 pm today (21 April) until 4 pm 28 April, with each detonation scheduled for later in the day when fewer boats are expected on the water.

An exclusion zone will be set up one hour before the scheduled detonations, which will be 430 metres from the blast site on the western foreshore of Tantangara Reservoir and extends beyond the existing marine exclusion zone.

Public access to the boat ramp won’t be permitted during the detonations, and nearby roadways will be patrolled to restrict access.

Trails and camping grounds near Tantangara will remain open to visitors in the National Park.
