Mrs Deutsch said the park had been at capacity for most of January with about 300 holiday makers hitting Lake Bolac during the traditional two week period.

"A lot from Melbourne, Ballarat, Warrnambool and even interstate," she said.

"Three quarters are our regulars and they have already booked again for Christmas this year.

"Everybody has been well behaved.

"Everybody is going out and water skiing and just enjoying it. I haven't heard much how the fishermen have been going, I think they've had a lot of bites and plenty of nibbles, but I haven't actually heard of anyone getting anything lately."

Regular campers noticed the Lake Bolac Caravan Park had undergone some changes in the past 12 months.

A new irrigation system is keeping the grounds looking green, while the installation of speed humps around the park is ensuring safety.

Mr Deutsch said the biggest addition to the park in the past year had been seven new cabins.

"They are mainly intended for shearers and harvesters, people who are here for several weeks," he said.

"I imported them from China myself. I had them checked out by a building engineer from Ballarat that they comply with all the relevant standards of Australia, which they do.

"The feedback has been great. They fit three people comfortably, but I have found shearers each book one just for themselves because they don't want to cram into it and it is like a home away from home."

Mr Deutsch said sites at the caravan park were also filling up quickly for the Australia Day long weekend this weekend.
