The Glenamoy River (Irish: Abhainn Ghleann na Muaidhe)[1] is a river in north County Mayo, in the northwest of Ireland. It contains sea trout and salmon.[2]
The Glenamoy River rises from its source at Glencalry and Barroosky, flowing for 23km (14miles).[3] The river flows west through several villages including Glenamoy, reaching Gortacragher, where it meets the Muingnabo River to form Sruwaddacon Bay. The length of the Glenamoy River is 14 km2.[3]
The Glenamoy River has an elevation of 8 metres.[4] It is particularly susceptible to fluvial flooding, in flood times, the river often becomes a roaring torrent sweeping away people and cattle.[5] There are numerous fishing pools on the river. Fishing continues in the river up to Autumn.[6]
The area surrounding the river contains peatland and farms. The river flows through the Slieve Fyagh Bog and Glenamoy Bog Complex protected areas. A number of surveys were conducted in the river catchment by Inland Fisheries Ireland in July 2017.[7]
In August 1933 after heavy rain the Muingnabo and Glenamoy rivers became swollen, cocks of hay and other debris washed downstream, three arches of the old bridge washed away due to the pressure from the rising waters.[8]
There is a fishing club, The Glenamoy Community Angling Association, which issues permits for angling on the river, which was set up in 1999.[9] Recently, there has been an addition of a wheelchair friendly pool in the fishery.[10]
