Dozens of people signed up to help maintain their local river during a village open day held at the weekend.
Around 100 people attended the event at Sedgeford village hall on Saturday, which was organised by the Norfolk Rivers Trust.
And 40 new volunteers signed up to the trust’s River Guardian programme, which encourages residents to take an active role in looking after their area’s waterways.
Jonathan Lewis, the trust’s catchment planning officer, said most of the new volunteers would be engaged in work along the river Heacham.
He added: “It was a really productive day.”
The River Guardians project allows people to take on a wide range of voluntary roles on projects such as riverbank planting or the monitoring of invertebrates in the water, which is vital towards making sure the river has not been polluted.
Visitors to the hall were shown some of the many species whose lives depend on the river and given information about the work of conservation groups.
Mr Lewis believes that, although the state of rivers had been brought into sharper focus by the floods that have devastated large parts of southern England in recent weeks, the trust is benefiting from a growing interest among local people for looking after their environment.
He said: “People come to us with real enthusiasm about getting involved in their river.”
