The course of the river through the districts of Freudenstadt , Calw and Pforzheim

The Nagold is a 90 kilometer long river in Baden-Württemberg and namesake of the city of Nagold . It flows in the Pforzheim city ​​center from the south into the smaller Enz .

physical geography

General

The Nagold mainly flows through the Black Forest . It flows around the town of Nagold (between Rohrdorf and Pfrondorf ) through the Heckengäu . At the Pforzheimer Kupferhammer it enters the Pforzheimer Enztal, which like the Heckengäu also belongs to the natural area of the Gaulandschaften .

According to convention, the Nagold is regarded as a tributary of the Enz. However, it carries more water at the confluence than the Enz upper course, is almost a factor of 2 longer than this and has a catchment area that is approximately 3.5 times larger. So the main line of the Enz-Nagold system runs hydrographically over them . The upper Enz, however, has the wider valley and maintains its direction of flow.

The Nagold runs in the upper reaches to Nagold mainly in an easterly and south-easterly direction. In the city of Nagold, it then almost turns around and then flows mainly in a northerly direction as far as Pforzheim. The Nagold has formed numerous loops, for example at Pfrondorf (Bettenberg), in Wildberg , at Hof Waldeck (Schlossberg, with Waldeck ruins ), at Tannenberg (Rudersberg, with ring wall). In Weißenstein there is a district on a small circular mountain with an abandoned loop.

The source of the Nagold is a source called Nagoldursprung near Urnagold ( Seewald municipality, Besenfeld district). After just a few kilometers, at Erzgrube, the Nagold to the Nagoldtalsperre is dammed. Up to the first town, Altensteig , the Nagold Valley is largely uninhabited. Before Rohrdorf the Nagold leaves the Black Forest, undergoes its major change of direction at the foot of the Hohennagold ruins and re-enters the Black Forest north of Pfrondorf.

The Nagold now passes the above-mentioned Umlaufberge as well as the most important places Wildberg, Calw , Hirsau and Bad Liebenzell . Between Dillstein and Pforzheim the Nagold leaves the Black Forest and flows in the former old town of Pforzheim from the right and from the south with the Enz, which, flowing in an easterly direction, flows into the Neckar at Besigheim .

Tributaries

The largest tributaries of the Nagold are:

  • the right Zinsbach with 13.3 km and 33.8 km² in front of the city of Altensteig
  • the left Köllbach with 10.0 km and 29.9 km² to the city of Altensteig
  • the right Waldach with 24.7 km and 157.1 km² at the Nagoldknie in the city of Nagold
  • the left Teinach with 15.4 km and 61.5 km² near Teinachtal
  • the right Würm with 53.9 km and 418.3 km² already in the urban area of ​​the mouth of Pforzheim

Political geography

The Nagold flows through the Freudenstadt and Calw districts , briefly touches the Enzkreis and flows into the Pforzheim district . Arranged after initial contact, it runs in or on the following regional authorities:

Until the great territorial upheavals around 1803 and 1806, the course of the Nagold was predominantly in the old Württemberg area. Smaller areas belonged to the margraviate of Baden or the Order of St. John . Altensteig, Nagold, Wildberg, Calw and Liebenzell are old Württemberg administrative towns, Hirsau and Reuthin are old Württemberg monastery administrative locations. The Kloster Hirsau has significance for European history. Rohrdorf am Oberlauf was the seat of a commander of the Order of St. John under Württemberg sovereignty. Today's parts of Pforzheim's core city (Weißenstein, Dillstein and Pforzheim itself) belonged to Baden.

Traffic geography

The Nagoldtal forms the backbone for various main traffic axes between Pforzheim and Altensteig. The north-south traffic between Pforzheim and Nagold and on to Horb is carried by the B 463 and the Nagold Valley Railway . Between Nagold and Altensteig, the Nagoldtal takes up the important east-west connection of the B 28 (whose traffic is increasingly shifting to the direct connection further south between Freudenstadt, Horb and Tübingen, as the B 28 between Tübingen and Freudenstadt via Herrenberg, Nagold and Altensteig makes a big curve to the north). A narrow-gauge railway, the " Altensteigerle " , operated between Nagold and Altensteig until it was closed in 1967 .

Economic geography

In the Black Forest, rafting was important until the beginning of the 20th century . Like the Enz, the Nagold was used to transport tree trunks. Some places lived mainly from rafting, for example Weißenstein. In the Black Forest, among other things, the timber industry is important, around Nagold agriculture is increasing . Industry and services play (s) a decisive role, especially in Pforzheim (jewelry, precious metals, watches, trade, administration), as well as in Ebhausen , Nagold, Kentheim (historic cotton mill), Calw ( district seat ) and Liebenzell (health resort).

Landscape protection areas

On its way to the Enz, the Nagold mainly flows through landscape protection areas .

  1. In the upper reaches of the Freudenstadt district there is the LSG Nagoldtal with 555.5 hectares , it was designated by the Freudenstadt District Office on July 1, 1991 under the protected area number 2.37.044.
  2. After moving to the district of Calw, the LSG is still called Nagoldtal , it is 4,384 hectares in size and was formed by order of the Calw District Office with the protected area number 2.35.037 on November 24, 1971.
  3. In the lower reaches the Nagold flows through the landscape protection area for the Pforzheim urban district up to its mouth , formed under the number 2.31.001 by ordinance of the Pforzheim Mayor's Office of December 12, 1994.
