Owenreagh River is of special scientific interest because of the associated riverine flora and fauna. The river has been modified over much of its length, particularly in the lower and middle reach sections, however it remains an important river for Freshwater Pearl Mussel Margaritifera margaritifera, with one of the largest remnant populations of this species known to exist in Northern Ireland.
The Owenreagh River rises at Black Lough in the Townland of Cragganconroe, from where it flows north-west to join the Owenkillew River. The river runs through predominantly agricultural land with some adjacent peatland in its upper reaches. The river has a pool, riffle and run dominated flow type with occasional deeper sections of glide.
