The River Otter is a river that rises in the Blackdown Hills just inside the county of Somerset, England near Otterford, then flows south through East Devon.^[3] It enters the English Channel at the western end of Lyme Bay, part of the Jurassic Coast, a UNESCO World Heritage Site. The Permian and Triassic sandstone aquifer in the Otter Valley is one of Devon's largest groundwater sources, supplying drinking water to 200,000 people.
