Lake Erie Basin
Lake Erie Basin consists of Lake Erie and surrounding watersheds, which are typically named after the river, creek, or stream that provides drainage into the lake. The watersheds are located in the states of Indiana, Michigan, New York, Ohio, and Pennsylvania in the United States, and in the province of Ontario in Canada. The basin is part of the Great Lakes Basin and Saint Lawrence River Watershed, which feeds into the Atlantic Ocean. 80% of the lake's water flows in from the Detroit River, with only 9% coming from all of the remaining watersheds combined. (The remainder (11%) is derived from direct precipitation into the lake.) A littoral zone serves as the interface between land and lake, being that portion of the basin where the lake is less than in depth. History The Lake Erie Basin was formed at the end of the Wisconsin glaciation. The basin was part of Glacial Lake Maumee until an eastern drainage opened at Niagara, at which point the Maumee River Watershed reversed its ...

Lake Erie Watershed
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lakes
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-blocke ...

Cedar Creek (Indiana)
Called ''Mes-kwah-wa-se-pe'' or "old redwood creek" by Native Americans, Cedar Creek is the largest tributary of the St. Joseph River, draining in the Eastern Corn Belt Plains of northeastern Indiana. It is long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed May 19, 2011 rising in northwestern DeKalb County and joining the St. Joseph just below the Cedarville Dam in Allen County. Origins and history Upper Cedar Creek originated as an ice-marginal channel at the western edge of the Erie Lobe of the Wisconsin Glacier and formed a single stream with the southwest-flowing Eel River which connected to the Wabash River. Lower Cedar Creek was a tributary of the ancestral Eel, carrying glacial meltwater under the ice through a tunnel valley known today as Cedar Creek Canyon. Blockage of the Eel's channel (geography), channel by outwash fan, outwash from the canyon and a decline in the volume of meltwater caused lower ...

Maumee River
The Maumee River (pronounced ) ( sjw, Hotaawathiipi; mia, Taawaawa siipiiwi) is a river running in the United States Midwest from northeastern Indiana into northwestern Ohio and Lake Erie. It is formed at the confluence of the St. Joseph and St. Marys rivers, where Fort Wayne, Indiana has developed, and meanders northeastwardly for U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed May 19, 2011 through an agricultural region of glacial moraines before flowing into the Maumee Bay of Lake Erie. The city of Toledo is located at the mouth of the Maumee. The Maumee was designated an Ohio State Scenic River on July 18, 1974. The Maumee watershed is Ohio’s breadbasket; it is two-thirds farmland, mostly corn and soybeans. It is the largest watershed of any of the rivers feeding the Great Lakes, and supplies five percent of Lake Erie’s water. History Historically the river was also known as the ''Miami'' in United ...

Great Black Swamp
The Great Black Swamp (also known simply as the Black Swamp) was a glacially fed wetland in northwest Ohio, sections of lower Michigan, and extreme northeast Indiana, United States, that existed from the end of the Wisconsin glaciation until the late 19th century. Comprising extensive swamps and marshes, with some higher, drier ground interspersed, it occupied what was formerly the southwestern part of proglacial Lake Maumee, a Holocene precursor to Lake Erie. The area was about wide (north to south) and long, covering an estimated . Gradually drained and settled in the second half of the 19th century, it is now highly productive farmland. However, this development has been detrimental to the ecosystem as a result of agricultural runoff. This runoff, in turn, has contributed to frequent toxic algal blooms in Lake Erie. The land once covered by the swamp lies primarily within the Maumee River and Portage River watersheds in northwest Ohio and northeast Indiana. The bo ...

Stream Capture
Stream capture, river capture, river piracy or stream piracy is a geomorphological phenomenon occurring when a stream or river drainage system or watershed is diverted from its own bed, and flows instead down the bed of a neighbouring stream. This can happen for several reasons, including: *Tectonic earth movements, where the slope of the land changes, and the stream is tipped out of its former course *Natural damming, such as by a landslide or ice sheet *Erosion, either **Headward erosion of one stream valley upwards into another, or **Lateral erosion of a meander through the higher ground dividing the adjacent streams. **Within an area of karst topography, where streams may ''sink'', or flow underground (a sinking or losing stream) and then reappear in a nearby stream valley *Glacier retreat The additional water flowing down the capturing stream may accelerate erosion and encourage the development of a canyon (gorge). The now-dry valley of the original stream is known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
