FIRE burned three hectares of grass at the Hume Power Station, near the viewing platform, last night.
NSW Rural Fire Service duty manager Julie Bartlett said the fire at Lake Hume Village was reported at 9.05pm and 16 tankers from the RFS, Country Fire Authority, and Fire and Rescue NSW extinguished it by 9.41pm.
The cause of the fire was unknown last night.
Meanwhile, lightning strikes Monday night are likely to have started a small bushfire in the Benambra National Park, south-west of Holbrook.
RFS southern border team operations co-ordiniator Marg Wehner said the fire had burnt about five hectares last night but was still burning in inaccessible country.
A National Parks helicopter was being used to contain the fire while heavy machinery arrived last night to help establish control lines.
About 18 were surrounding the area to protect property should the fire move into the open.
