The Hasel is a 26.4 km long right tributary of the Werra from the Thuringian Forest in southern Thuringia over the nominal source arm, 32.5 km over the Lauter and even 38.1 km over the Schwarza together with Schönau .

course

The hazel rises in Suhl below the Friedberg. A few tributaries already flow into the Hasel in Suhl. It is spanned by the Haseltal viaduct . After a few kilometers, the Steinbach and Lauter then flow into the Hasel. The hazel then continues to flow through the Hasel valley. After being polluted by industrial wastewater in the past few decades, the river is now very clean again. In Ellingshausen in the 1980s a dam was to be built, the project but it was established. After 26.4 km the Hasel flows into the Werra at Einhausen .

Tributaries

The river system of the Hasel is fan-shaped around the south-western Thuringian Forest . The low mountain range is distinctly divided into individual mountain ridges by the river arms.

Below is a clockwise list from west to east, which also takes higher-order inflows into account. For an order in the flow direction of the Hasel, the table must be arranged according to the river code numbers (DGKZ).

The hazel in Dillstädt

The hazel contributes more than a third of the water to the wedding with the Werra; about the same amount had previously flowed from the fan of the Werra sluice , which adjoins that of the Hasel immediately to the southeast. This proves the dominance of the two river systems within the lower Werra.

On the main flow issue

Of the total of 4.65 m³ / s that the hazel pumps water, 2.35 come from the Schwarza system, whose catchment area up to the mouth is also larger than that of the hazel up to there. The Hasel over the Schwarza is also significantly longer at 38.1 km compared to 26.4 km.

Within the Upper Hasel, the official spring arm is actually a tributary of the Lauter (discharge: 0.895 m³ / s, length of the Hasel over the Lauter 32.5 km), which in turn arose from the equal confluence of the Lauter and Mühlwasser (see table above ).
