Environmental projects including carbon farming, tree planting and eco-tourism are included in a draft plan for future use of six thousand hectares of land set aside for the now scrapped Tillegra Dam.

Hunter Water says the community plan which makes 11 recommendations for the Tillegra land is now on public exhibition for the next 28 days.

The recommendations for economic opportunities in the environmental, agricultural, tourism and recreational sectors include setting up a 400 hectare green corridor for carbon farming and tree planting along the banks of the Williams River.

A community information session next month at Dungog will be attended by the environmental planning consultants who prepared the plan over the past 12 months.

Hunter Water spokesman Jeremy Bath says the document seeks to maximise potential uses for the land.

"These recommendations identify economic opportunities in the environmental, agricultural, tourism and recreational sectors," he said.

"The plan is an exhaustive examination of the Tillegra region, looking at issues such as ecology and topography, soil type and agriculture and culture."

Mr Bath says residents have already contributed to the preparation of the document, but they are now being asked to comment on its recommendations.

"Hunter water is very keen to continue to hear the thoughts and feedback not just the people of Dungog, not just the people of the Tillegra but all of Hunter Water's customers across the lower Hunter," he said.

"We're wanting to know their thoughts are about the draft plan.

"There's a number of ways people can give that feedback."
