The gauge level does not directly correspond to the actual depth of the river (zero level is not at the riverbed); instead, as is the case with most Rhine gauges, the actual depth of the navigation channel is defined as: [2] Gauge value + Ideal depth of the navigation channel (1.9 m) − Equivalent water level (0.78 m)
A mechanised waste water plant opened in 1905 and five purification plants now filter the water before releasing it into the Rhine. [1] [3] By 1933 the length of the system measured 735 kilometres (457 mi), [3] and by 2011 it had expanded to 2,400 kilometres (1,500 mi). [4]
Watersheds of Illinois is a list of basins or catchment areas into which the State of Illinois can be divided based on the place to which water flows.. At the simplest level, in pre-settlement times, Illinois had two watersheds: the Mississippi River and Lake Michigan, with almost the entire State draining to the Mississippi, except for a small area within a few miles of the Lake.

[5]Colonel William Clark Falkner, great-grandfather of authors William Faulkner and John Faulkner, was a prominent resident of Ripley in the mid to late-19th century.
Water area is 2,325 square miles (6,020 km 2); Lake Michigan accounts for most of this. Charles Mound in the northwest Driftless Area is the highest point in the state at 1,235 feet (376 m) above sea level. The Mississippi River at Cairo, Illinois is the lowest point, at 279 feet (85 m). Average elevation is 600 feet (180 m) above sea level.
Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake. The Rhine carries very large amounts of debris into the lake – over three million cubic meters (110,000,000 cu ft) annually. [29] In the mouth region, it is therefore necessary to permanently remove gravel by dredging.
The Illinois Waterway system consists of 336 miles (541 km) of navigable water from the mouth of the Calumet River at Chicago to the mouth of the Illinois River at Grafton, Illinois. Based primarily on the Illinois River , it is a system of rivers, lakes, and canals that provide a commercial shipping connection from the Great Lakes to the Gulf ...
Map of the Des Plaines River drainage basin. The Des Plaines River (/ d ɪ s ˈ p l eɪ n z / diss-PLAYNZ) is a river that flows southward for 133 miles (214 km) [2] through southern Wisconsin and northern Illinois [3] in the United States Midwest, eventually meeting the Kankakee River west of Channahon to form the Illinois River, a tributary of the Mississippi River.
