The Muingnabo River (Irish: Abhainn Mhoing na Bó)[1] is a river in north County Mayo, in the northwest of Ireland. It flows into the Atlantic Ocean via Sruwaddacon Bay.
Sruwaddacon Bay, the Glenamoy River and the Muingnabo River are part of the Glenamoy Bog Complex Special Area of Conservation.[2]
Before the famine, the Wood family from Yorkshire owned the townland surrounding the river. The Woods built a hunting lodge by the river, using a salmon net with a bell alert system to detect caught fish. They cultivated oil seed in a nearby area called "Park na Rapa".[3]
A road connecting two nearby villages, Carrowteige and Glenamoy, was built in 1846. As there was no bridge yet constructed over the Muingnabo River, a fording point was used. Annie Brady, the wife of a local Fisheries Inspector fundraised for a new bridge, completed in 1886. The current bridge replaces Brady's bridge, destroyed by floods in 1933.[4]
