The Tamar Natural Resource Management program manager took Children's University pupils from Kate Reed Reserve to QVMAG to learn about the waterway this week.

"The idea of the project was to look at a small piece of the puzzle of the catchment. We've followed the rivulet from what we call the source to the sea," she said.

The program, funded by TasNetworks, saw students explore the waterway through cultural talks, water testing and bug catching.

"We're trying to educate people about the natural processes of the river, and how issues with silt and sediment are really natural."

With 15 per cent of Tasmania's landmass ending up in the Tamar basin, Tamar NRM education officer Trish Haeusler said the catchment's health is everyone's responsibility.

"We live in a catchment and our activities really affect that, particularly water quality which affects us all," she said.

The river system features a diverse ecosystem of wildlife and the students were allowed to also explore local indigenous plants and knowledge.

But the day wasn't just for the kids, with parents tagging along to learn as well.

Crystal, who came with her daughter, said the day was valuable for everyone.

"We've come across different spots in one system we didn't already know about, and we've been living here our whole lives," she said.
