Afon Dulyn (Welsh: Black Lake river) is the outflow from Llyn Dulyn, a lake in the Carneddau mountains in North Wales. It is a tributary of the River Conwy.
Just below Afon Dulyn the river is joined by Afon Melynllyn, a small river flowing from neighbouring Llyn Melynllyn.
The river does not carry a great deal of water because water is transferred from Llyn Dulyn to the reservoirs of Llyn Eigiau and Llyn Cowlyd. |
