The Itter is a 19.3 km long, southwestern and orographically left tributary of the Diemel in the Waldeck-Frankenberg district in Hesse and in the Hochsauerlandkreis in North Rhine-Westphalia .

etymology

In historical sources the Itter is also mentioned as Itterbecke and Itterbach . In his work The Place Names of the Principality of Waldeck, Louis Friedrich Christian Curtze traced the name Itter back to Celtic origins. The meaning of Itter in Celtic is water.

geography

course

The Itter rises in the northern part of the Rothaargebirge and in the northwest part of Hesse in the nature reserve Alter Hagen near Willingen a few meters east of the border with North Rhine-Westphalia on the seam line of the mountain regions Upland and Sauerland . Its source is in a wooded landscape at about 770  m above sea level. NHN between Hopperkopf ( 832.3  m ) in the southeast and Clemensberg (approx.  837  m ) in the west.

From there, the Itter flows in a northerly direction east past the Mühlenkopf and Willingen- Stryck to Willingen , crossing under the Willingen Viaduct , and then east past the Hohen Eimberg ( 806.1  m ) to Willingen-Schwalefeld . A little further northeast, the river runs for around 4 km as a border river between the federal states mentioned at the beginning in the northeast. It flows roughly parallel to the Diemel, which runs a few kilometers further east, and touches the Brilon district of Bontkirchen as a border river .

About 2.7 river kilometers below the village, the Itter flows into the Hessian community of Diemelsee 3.2 km west of its Heringhausen district at 376  m altitude in the western arm of the Diemelsee reservoir , within the Diemelsee nature reserve , where it flows into the Diemel .

Catchment area and tributaries

The catchment area of the Itter is 52.065 km². Their tributaries include with orographic allocation (l = left-hand side, r = right-hand side) , length of the water, mouth location with Itter stream kilometers and - if known - catchment area size and mouth height in meters (m) above sea level (viewed downstream) /:

  • Hemeke (1; 1.7 km), above Stryck (near km 16.05), at approx.  635  m
  • Aarbach ( Aar ; r; 8.8 km), between Willingen and Bontkirchen (near km 6.3), 9.006 km², at approx.  443  m
  • Dommelbach (l / r; 4.9 km), above Bontkirchen (near km 4.2), 9.423 km², at approx.  414  m

Curiosities about length and catchment area

The interesting thing about the Diemel tributary Itter is that it is 3.1 km longer up to its confluence with the Diemelsee than the Diemel up to its influence in the reservoir (19.3 km compared to 16.2 km) and also over a 9 , 33 km² larger catchment area (48.294 compared to 38.964 km²). Therefore, strictly speaking, the Itter, which was historically run as a tributary, would at least be regarded as an equal source river of the Diemel.

Watersheds

history

Geographically, the Itter lies in a river landscape around 240 million years old. The source region is located in the Rhenish Slate Mountains and is assigned to the Devonian and Carboniferous periods .

level

Itter gauge Kotthausen III ( 377.68  m above sea level ; kilometers: 3.40)

The waterways and shipping authority Hann. Münden operates a measuring station to record the inflow of the Itter into the Diemelsee. The facility is located on the Itter in the area of ​​the state border between North Rhine-Westphalia and Hesse. The system with the gauge house is located in front of the inlet of the Itter to Diemelsee in the area of Kotthausen III . The measured level values ​​are available online.
