Title: Shannon River (Western Australia)
Content:  Shannon River is a river located in the Great Southern region of Western Australia. The river rises in the forests to the west of Lake Muir and flows in a southerly direction, crossing the South Western Highway just east of Shannon then continuing south through the Shannon National Park before entering the Broke Inlet. The only tributary of the river is Fish Creek. The water quality of the river is excellent, fresh and low in sediments. Sandbanks bar the mouth of the river where in enters the inlet.
Title: River Shannon
Content:  By tradition the Shannon is said to rise in the Shannon Pot, a small pool in the townland of Derrylahan on the slopes of Cuilcagh Mountain in County Cavan, Republic of Ireland, from where the young river appears as a small trout stream. Surveys have defined a 12.8 km2 immediate pot catchment area covering the slopes of Cuilcagh. This area includes Garvah Lough, Cavan, 2.2 km to the northeast, drained by Pollnaowen. Further sinks that source the pot include Pollboy and, through Shannon Cave, Pollahune in Cavan and Polltullyard and Tullynakeeragh in County Fermanagh, Northern Ireland. The highest point in the catchment is a spring at Tiltinbane on the western end of the 
Title: Shannon, Georgia
Content:  Shannon is located in northeastern Floyd County between Rome and Calhoun, just off Highway 53. According to the U.S. Census Bureau, the Shannon CDP has a total area of 13.0 sqkm, of which 12.9 sqkm is land and 0.1 sqkm, or 0.86%, is water.
Title: River Shannon
Content:  crossing-points between Limerick city in the south and the village of Dowra in the north. The river takes its name after Sionna, a Celtic goddess. Known as an important waterway since antiquity, the Shannon first appeared in maps by the Graeco-Egyptian geographer Ptolemy (c. undefined 100 – c. undefined 170 AD). The river flows generally southwards from the Shannon Pot in County Cavan before turning west and emptying into the Atlantic Ocean through the 102.1 km long Shannon Estuary. Limerick city stands at the point where the river water meets the sea water of the estuary. The Shannon is tidal east of Limerick as far as the base of the Ardnacrusha dam.
Title: O'Shannassy River
Content:  The O'Shannassy River rises within the Yarra Ranges National Park on the slopes of the Yarra Ranges, within the Great Dividing Range, below Mount Observation, approximately 80 km east of Melbourne. The river flows generally south by southwest, joined by two minor tributaries, before being impounded to create the O'Shannassy Reservoir, part of Melbourne's water supply system. Below the reservoir the natural flow of the river is diverted via the O’Shannassy Aqueduct and then reaches its confluence with the Yarra River west of the locality of. The river descends approximately 406 m over its 15 km course, before being diverted via the aqueduct. The O’Shannassy River catchment is identified as an Essentially Natural Catchment by the Land Conservation Council.
Title: River Shannon
Content:  in the 12th century, although a map of the time showed this river as flowing out of the south of Ireland. There are some tributaries within the Shannon River Basin which have headwaters that are further in length (from source to mouth) than the Shannon Pot source's length of 360.5 km, such as the Owenmore River, total length 372 km in County Cavan and the Boyle River, total length 392.1 km with its source in Mayo.  The River Shannon is a traditional freshwater river for about 45% of its total length. Excluding the 63+1/2 mi tidal estuary from its total length of 224 mi, if one also excludes the lakes (L. Derg 24 
Title: Shannon River Basin
Content:  There are some tributaries within the River Shannon system which have headwaters that are further in length (from source to mouth) than the Shannon Pot source, such as the Owenmore River (County Cavan) in County Cavan, which flows west for 14.5 km through the valley of Glangevlin before joining the Shannon about 3 km below the Shannon Pot at Lugnashinna, thus adding 11 km to the Shannon's overall length, bringing it to 372 km. Also the Boyle River has a similar claim. The river flow from the furthest reaches of the Boyle catchment to Limerick city has a measurement of 290 km. When added to the Shannon's 63.5 miles estuary this gives a total river flow of 392.1 km, which makes it the longest river within the River Shannon basin (from source to mouth)—31.6 km longer than the Shannon Pot source. Thus the Boyle-Shannon river can be regarded as having the longest natural river flow in Ireland.
Title: Shannon Callows
Content:  The Shannon Callows (Caladh na Sionainne) are areas of flat land along the shores of the River Shannon. These areas lie between Athlone in County Westmeath, where the river flows out of Lough Ree, and Portumna in County Galway, where it enters Lough Derg, in central Ireland. The shallow grade of the river here results in occasional flooding of the Callows.
Title: Shannon River (Minnesota)
Content:  The Shannon River (Minnesota) is a river of Minnesota.
Title: Shannon Creek
Content:  Shannon Creek is a short tributary to the Baker River in Whatcom County, Washington, near the southwest border of North Cascades National Park. It rises in two forks a few miles south of Mount Shuksan; the glacier-fed north fork begins at elevation 5016 ft, and the non-glacial south fork begins at 2611 ft. Roughly halfway through its length, the two forks join and then flow into Baker Lake reservoir, at elevation 725 ft. Shannon Creek joins the Baker several miles downstream of Sulphide Creek and upstream of Swift Creek, a much larger south-flowing drainage.
