RIPPLE, which stands for Rivers Involving People, Places and Leading by Example, is a community-based project that will help manage and conserve the Ballinderry River.
With its source high in the Sperrins, the Ballinderry winds its way through Co Tyrone to Lough Neagh, the largest freshwater lake in the UK.
It is home to many unique and endangered species including the freshwater pearl mussel, Dollaghan trout, otter and Atlantic salmon, and supports business, tourism and leisure activities in and around the Cookstown area.
RIPPLE is a WWF project run in partnership with Ballinderry Fish Hatchery Ltd and jointly funded by Heritage Lottery Fund.
RIPPLE stands for Rivers Involving People, Places and Leading by Example.
Life abounds during the fresh mornings and long warm evenings of the summer.
Everyone living near the river is being encouraged to get involved in protecting and conserving it.
