Wellington Shire Council members and Sale Rotary Club members, partners in the project, had a sneak peek of the walking track at Long Lagoon on Sale Common this week.

Mayor Darren McCubbin, councillor and Sale Rotary Club member Leo O'Brien and project benefactor John Leslie also helped nail in the final plank on the boardwalk section of the trail.

Cr McCubbin said the council was pleased with the progress of the project and couldn't wait to see the finished product.

"It'll be a wonderful tourism resource for those who are visiting our shire ... and it'll also be a great asset for our community,'' he said.

"There is also the potential for providing a connection between Sale and Longford.''

Work on the River Heritage and Wetland Trail began in January this year.

Stage two extended the existing trail from the Sale Canal to the Thomson River Caravan Park up through the Sale Common to the Swing Bridge.

A link has also been provided to create a circular walk around lakes Guyatt and Guthridge.

The end result will be a scenic two hour and 15 minute circular walk spanning 15km.

According to Wellington Shire Council's Environmental Management Plan, the trail extension will enhance the wetlands by providing an opportunity to appreciate their scope.

Sale Rotary Club member and project co-ordinator Alan Lewis said Rotary members had invested many hours into preparing the trail.

"Our working bees have been blazing the trail ... there's been a substantial amount of volunteer labour and we worked hard to raise the money for the project,'' he said.

Sale Rotary Club, with the support of benefactor John Leslie, have raised $150,000 for the project.

The project is also being funded by a $100,000 Victorian Government's Flood recovery program grant and $20,000 from Wellington Shire Council.
