Most other rivers arising on Exmoor flow north to the Bristol Channel. These include the River Heddon, which runs along the western edges of Exmoor, reaching the North Devon coast at Heddon's Mouth, and the East and West Lyn rivers, which meet at Lynmouth. Hoar Oak Water is a moorland tributary of the East Lyn River, the confluence being at Watersmeet. The River Horner, which is also known as Horner Water, rises near Luccombe and flows into Porlock Bay near Hurlstone Point. The River Mole arises on the south-western flanks of Exmoor and is the major tributary of the River Taw, which itself flows northward from Dartmoor. Badgworthy Water is one of the small rivers running north to the coast and is associated with the Lorna Doone legends.
