any importance. Nowadays, the
Dreisam with its bank paths and meadows serves as a recreational spot for taking walks, swimming or barbecueing. The Dreisam is also of significance in the matter of individual traffic since on the south bank there are bikeways and on both sides motorways that lead to the city center of Freiburg and the “Zubringer Mitte” (highway 31a) to Beratzhausen. Since 2011, the Dreisam has also been used as the venue of an annual duck race fund-raiser that starts in Freiburg's city center. Thousands of numbered rubber ducks are tossed into the river and flow a few hundred meters upstream before being fished out again.

from the river at
Sandfang. It is used to supply the Gewerbekanal, an industrial canal, and the famous Freiburg Bächle with water. A division of the river into a northern and southern branch takes place in the historic city center. The majority of the southern branch flows back into the Dreisam directly west of the Höllentalbahnbrücke bridge which is located in the Stühlinger district. The remaining water runs through the areas Eschholz and Bischofslinde towards the west and ultimately flows back into the Dreisam near Lehen.

However, on
December 23, 1991 there was a flood that caused damage in the eastern part of Freiburg. The riverside paths below the bridges of the Mannheim-Basel-Karlsruhe-railway, called Rheintalbahn in German, are often flooded during high water. Even though warning signs were installed along the path, two cyclists died there in 2010 and 2013 during a flood. In order to prevent accidents like this, the city is planning to install boom gates along the path.

It overcomes 199m height, from Kirchzarten (337m NHN) until its mouth into the Elz (178m) at Riegel. 135m above or southwards of the river mouth the Glotter leads into the Dreisam, coming from south-southeastern. Northeastern of St. Michaelsberg (241 m NHN), the Alte Dreisam, from south-southwestern, flows into the direct mouth of Dreisam and Elz.

discharges can be measured in spring as a result of melting snow. Another major discharge can also be measured in summer or fall depending on when it is raining the most. There are a couple of rivers that coalesce with the
Dreisam, which are the headwater streams Rotbach and Wagensteigbach and (ordered towards downstream): Krummbach (which is also called Zastler Bach in the upper section), Brugga, Eschbach and

primarily of solid rock, absorbs little water and hence leads to quick drainage, particularly in cases of heavy rainfall. Because of melting snow and heavy rainfalls in spring, the maximum amount of draining water runs off in April. Even though the heaviest rainfalls occur in summer, the high water consumption of the local vegetation only leads to secondary drainage maximums.

The waters of the

In March 1896 a historic flood killed two people and destroyed several bridges. Among the people that were killed was Carl Siegel, a German jurist. Nowadays floods do usually not cause major damages since the

to the Pegel Ebnet the average slope is at 21° or rather 43% downhill grade. Because of its round shape the area has a high aspect ratio of 0.7 and a high circularity ratio of 0.55 which leads to temporal runoff concentration and thus can quickly lead to flooding. The aquifer, which consists
