The Brotenaubach is a 7 km long stream in the northern Black Forest in the Rastatt district and on its eastern border with the Calw district , which joins the left and smaller Dürreych to the Eyach a little east of the Dürreych von Gernsbach residential area from the right and southwest . His valley is the Brotenau .
etymology
The name of the stream is derived from that of the valley, which is recorded on old maps as Breitenau . Its name is made up of the adjective broad , which is pronounced as [ bʀɔɐt ] in the Swabian language of the area , and the basic word Au , which means a broad floodplain.
geography
course
The Brotenaubach arises in the western state forest Kaltenbronn close to the watershed to the valley of the Reichenbach in the west between the Hohloh ( 989 m above sea level ) in the southwest and the Langmartskopf ( 942 m above sea level ) in the north at the saddle Teufelsgrab at about 849 m above sea level. NHN at the Kreuzlehütte on the Reichental district of the city of Gernsbach.
The first about 800 meters it runs eastwards and deepens its initial trough to a valley until it reaches about 778 m above sea level at the first valley direction . NHN takes up its right upper course Rossstallgraben , which itself flows out of the Mannsloh moor , but with its right tributary Seegraben also partly drains the Wildsee and the surrounding large raised moor. Then the Brotenaubach turns its course to the northeast. Further down in the next, elongated valley direction, he passes the only residential area Brotenau on its bank. Then the red water from the south-south-west flows in again from the right , it drains the Wildseemoor on its east side.
The last major tributary Lehenbächle , with 2.2 km the longest and with 2.2 km² also the richest catchment area, flows in turn from the right across from the Große Wiese , at the northeastern tip of which the Brotenaubach is less than half a kilometer further down to about 568 m above sea level . NHN converges with the Dürreych coming from the west-southwest to the Eyach .
The Brotenaubach is 7.1 km long and has a gradient of about 326 m (approx. 45 ‰) on the main strand. The upper inlets arise up to 926 m above sea level. NHN .
Catchment area
The 15.1 km² catchment area of the Brotenaubach extends from a little south of the source of the Brotenaubach to its mouth about six kilometers and across it reaches a width of up to two and three quarters kilometers. It is a closed forest area with the exception of a few small clearings with the Brotenau estate as the only settlement area.
The catchment area of the Dürreych borders the entire northwestern watershed . On the east, south-east and south, their tributaries Rennbächle , Güterbächle , Rollwasserbach flow one after the other , approximately eastwards and from the left to the Großer Enz , and finally the Kegelbach . All of these competitors ultimately also drain into the Enz . Only behind the western watershed does the Reichenbach drain westwards to the Murg , which is why it is a section of the larger watershed between the Rhine in the west and Neckar in the east. Near the catchment triangle of Reichenbach, Dürreych and Brotenaubach is also the one with about 945 m above sea level. NHN highest point of the Brotenaubach catchment area.
The catchment area is in the Black Forest Central / North Nature Park , in it (only) the northern part of the eastern part of the Kaltenbronn nature and forest reserve around the Wildseemoor, and also the upper part of the Eyach- and Rotenbachtal nature reserve in the form of a ribbon along the Brotenaubach. The rest of the catchment area, which is not under nature protection, is part of the Middle Murgtal landscape protection area . Except for tiny fringes, the catchment area is also in the water protection area Eyachspeicher and around the protection area for the Wildseemoor there is another forest protection area Kaltenbronn with small gaps.
The whole area naturally belongs to the sub-area Grindenschwarzwald and Enzhöhen of the Black Forest .

Brotenau
The Brotenau -called V-shaped valley of Brotenaubachs located primarily in the Middle Bunter Sandstone , the mouth region occurs Permian to light. Ice Age kar formations shape the north to east facing valley slopes. The brooks from the Altlochquelle and from the Gewann Lochbrunnen, mentioned at the tributaries, drain such hollows. The stream was used for logging in the 18th and 19th centuries ; the inflow over the Seegraben from the Wildsee served as a surge water.
The residential area Brotenau von Gernsbach, a single property in the middle valley, is the only settlement area in it.
