348:, the water volume is regulated by means of a watergate. That way, 200 liters (according to a different source, 250 liters; about 50 gallons) of water can flow into the Bächle's network. Thereby it is completely refilled every 8 minutes. Thanks to the difference in altitude between east and west of Freiburg's old town, the Bächle flow downwards in a north-west direction with a natural base slope of 1° to 2°. The main distribution happens in Oberlinden. It's also possible to branch off some water in order to water the alte Linde (old lime-tree) from the year 1729. After running through the city, the water flows back into the canals at Predigertor. It is redirected into the Dreisam at the Höllentalbahnbrücke and near Lehen. However, some of the canal's water is also flowing from the northern stream course through different streams into the Glotter. Back when the Bächle were still used for the watering of fields, it was also redirected at the Christoffeltor and the Mönchstor over the city walls.

system of Bächle was instead elevated in order to supply newer parts of the city with water. Thus, houses from the first half of the twelfth century are in line with a lower street level and all constructions after 1175 with a higher one. Those aggradations made the ground floor of a lot of houses impassable from the street, so that they were either raised or simply had front doors built at the level of their upper floors - which were then at street level. The amount of newly constructed buildings around 1175 thus surpassing the number expected by natural population growth, presumably also because the aggradations were used to substitute wooden constructions with stone ones.
279:"For several days they have been replacing brook, which until now ran through Grünwälderstraße, with cement tubes. The residents of this road are losing a beneficial amenity, which is so pleasing to the eye for visitors to Freiburg compared with other cities. In any case there must have been very weighty authoritative reasons, which justify such a change, without listening to the primary wishes of the residents of the street, regarding the Bächle. We feel that the expressed concerns can’t be shared, because those in powerful positions intend to conceal the canals. For the above-mentioned, change has been evoked by multiple unpopular statements from participating parties."
453:"On the longs walks through the traffic-free city center one crosses a channel carelessly - and suddenly a little boat made out of paper is floating by. Children are playing in the water in the middle of the business center of a city. Fresh water from the Black Forest is briskly flowing next to the streets, taking with it the dust and cleaning the air. At least this is the argument when people from the north complain about the absurd and dangerous mantraps. Of course one wants to respond with something that gives an illusion of practical use. But I think, the Bächle are less for cleanliness than for the soul."

caught in the Bächle grills. Furthermore, the so-called “Bachabschlag” takes place annually in autumn and during a weekend in spring, when the water from all of the canals and Bächle is drained. The “Bachabschlag” is used not only for cleaning but also to check for damage and if necessary, repair. Further reasons for stopping the Bächle are for example: road works, the
Freiburg wine festival and the Carnival/Fasching parade in which Hästräger, (those wearing a Carnival costume) from the “Bächleputzer” jester's guild (established in 1935) can be marveled at.

operated manually. It was as recently as 2009 that an automatic inlet construction was put into operation. The canal fills a mining tunnel at the bottom of the
Schlossberg. This roughly 400 meter (around 1130 feet) long tunnel was partly bricked and partly sculpted into rock. Memorial stones for master builders, master-workmans and mayors of Freiburg can be found there. A historic map implies that the canal was an open stream before the construction of the Vauban's stronghold from 1679 onward.

248:. This system was sufficient for the supply of drinking water for the population, but it did not cover the demand of service water for animals outside of the city walls. Therefore, additional water was branched of the Dreisam and drained through the city's artificial waterstreams, called "Runze". Since for a long time the term "Runze" was used for both the Bächle and for canals, it is not possible to properly distinguish the two facilities in historical sources.

based upon the fact that the Bächle should have attracted his attention after a day in the city and that it should "so long as somehow possible keep holding on to such a characteristic, beautiful and hygienic quirk as presented by the Bächle". At least, in consequence of the accidents at the end of the 1960s, the city instituted that the bottom plates of the Bächle, among others the ones in the Salz- and
Bertholdstreet, were put higher.

Witnesses reported that after the raid, the Bächle came in handy, because the industrial streams were buried and the water pipes destroyed, therefore deeming the hydrants useless. Without the water from the Bächle, the area of Oberlinden, the historic department store, the Wentzinger house and other buildings wouldn't have been able to be saved.

it took until the beginning of the 1950s for the Bächle to be able to run again in the rebuilt city. In 1952, the FAC ("Freiburger
Automobil-Club") demanded the removal of these "traffic obstacles". A visitor in 1956 proposed to attach references of the Bächle to the place-name signs. At roughly the same time a merchant filed a suit against the town of Freiburg after having driven into a Bächle in

important role of the Bächle. It directly requested the fountain craftsmen to "instantly adjust the water in fountains and city streams according to the area of the blaze". Since this way, there was fire water available directly available at the location of the fire, it wasn't necessary to build up long bucket brigades to the next water standpost anymore.

the 20th century it changed and remains the same to this day: the bases are paved with granite or Rhine gravel. The Rhine gravel is also used for paving, but is hard to come by. This requires a specially educated paver. The lining of the Bächle can also be made with Rhine gravel, porphyry or basalt.
363:
At first the Bächle were flowing freely in shallow ditches at street level, but in the nineteenth century a sandstone frame was put in to control the flow of the Bächle. Since the construction in the 19th century the base of the Bächle was cemented and the lining was made up of granite tiles. Then in

The modernization of the drinking water and water network from 1850 and the production of fire hydrants in the late 19th century meant that the importance of the Bächle decreased as a source of water to fight fires. However, in the following century they helped to extinguish fires during the
British

Ever since their existence the Bächle transported rainwater out of the town, carrying along all sorts of dirt. In order to be a positive sight at daytime, no „substances causing offence" („Ärgernis erregende Stoffe") were allowed to be disposed of at daytime. Council regulations from the 16th century

By
November 1945, mayor Wolfgang Hoffmann had already called for the courses of the stream to be cleaned in order to start using the Bächle again. Because of the cleaning work, the Bächle often couldn't flow properly, and at times, the Bächle themselves exacerbated the work. Due to these two factors
270:
After their way through the town, the Bächle were used to irrigate fields. The water was funneled to the fields across the moat by wooden bridges called „Kähner“. The „used“ Bächle water increased the value of the fields massively by being a very nutrient-rich fertiliser. The Bächle floated snow out
351:
The ‘Runzknecht’ ensures the distribution of water. 142 brass valves help the regulation, through which the water can also be turned off during the cleaning of the Bächle. Furthermore, there are plugholes on the bases of the Bächle, which connect the Bächle water systems with the central sewerage

The Bächle originally ran down the middle of the road, which can only be seen today in the Market street. They were considered because of the massive increase in the population in the 19th century as an obstacle for the rise in traffic. Between 1840 and 1851 they were laid at the edge of the road,

Around the year 1180 some street levels in the city were raised by up to three metres (10') with layers of gravel. Unlike in many other settlements this was not done to protect against floods since the riverbed of the
Dreisam is significantly lower than the city. It is now believed that the entire

Accommodated to the width of each respective street, the Bächle themselves are each different sizes. The widest Bächle with a width of around 75 cm (2'6") is located near the
Schwabentor and the smallest one which is approximately 15 cm (6") wide runs through the narrow old city alleys.
340:
Far above the old town, at the
Kartause's grit channel, a watergate directs water from the Dreisam into the canal. Before being moved to its present-day location in 1852, this water conduit was located below the Sandfangbrücke. Up until the beginning of the 21st century, this watergate had to be

The responsibility of keeping the streams clean rests on two full-time “Bächleputzer” (previously: “Bachräumer”) (bächle cleaners / Bach clearers) since at least 1789, who are employed by the city administration of Freiburg. Twice a day they clear the Bächle of rubbish and leaves which also get

The Freiburg residents did not want to abandon the Bächle. New Bächle were even produced until 1858, for example, in the ‘Roß-’, ‘Engel-’, and ‘Kasernengasse’ (streets), and also the timber market place. For this task, according to the
