Editing Lough Allen (section)

==Geography==
Lough Allen, out of which the Shannon takes its source, is nine miles long, and three miles wide.{{sfn|Boate|1653|pp=74}} The lake is shaped like an [[isosceles triangle]]. The Shannon enters the lake at the wider northern end and leaves the lake at the narrow southern end. Other rivers that feed the lake include the Diffagher (northwest), the [[Yellow River (County Leitrim)|Yellow]] (northeast), the Stoney (east) and the Arigna (southwest). The [[R280 road|R280]] [[Regional road (Ireland)|regional road]] skirts the west side of the lake, while the [[R207 road|R207]] follows the east bank,<ref name="isbn0-312-27048-8-p779">{{cite book |author=Bord Failte |title=Bord Failte Ireland Guide, 4th Edition |publisher=St. Martin's Griffin |location=New York |year=2001 |isbn=0-312-27048-8 |url=https://books.google.com/books?id=1tNEldGNn8sC&q=%22Lough+Allen%22+lake+r280&pg=RA1-PA779 |page=779 |access-date=20 December 2020 |archive-date=24 September 2021 |archive-url=https://web.archive.org/web/20210924184949/https://books.google.com/books?id=1tNEldGNn8sC&q=%22Lough+Allen%22+lake+r280&pg=RA1-PA779 |url-status=live }}</ref> from Ballinagleragh to [[Drumshanbo]].
