geography

Headwaters

Its left upper course rises at an altitude of 1470 to at most 1540  m above sea level. NHN on the northwest slope of Feigenkopf ( 1866  m above sea level ) in the Ammergau Alps . After moving on the uppermost course to the west-northwest between the northernmost rocky mountains of the mountains, it turns around the last Baumgartenkopf on the north-northwest run between Matten and Bergwald and is now called Baumgartengraben and finally Lainbach . It ends at about 936  m above sea level. NHN northeast of the Reiselsbergshütte in the Sperbersau .

There it runs together with the Röthenbach coming from the northeast , which at about 1550  m above sea level. NHN not far from the Bleickhütte on the western slope of the Niederbleick secondary peak from the Hohen Bleick ( 1638  m above sea level ) rises, first flowing a little to the west, then for a long time to the southwest and finally south. This upper course is longer than the left, almost reaches its sub-catchment area and also rises higher. Nonetheless, the left upper course is part of the main line of the half-lamb.

course

From the confluence of the draws Halblech in a gorge-like forest valley initially about to the west of the village of Buching the municipality Halblech to. Between the Buchberg ( 1142  m above sea level ) on the left and the Mühlschartenkopf ( 1308  m above sea level ) it leaves at about 860  m above sea level. NHN the mountain landscape and before Buching turns to the right on from now on flatter, initially northern course and passes the eponymous area of ​​the community on the right slope. Behind this it turns for its 3 km long lowest run to the northwest and finally flows at 746  m above sea level. NHN high dammed Premer Lechsee to the upper Lech .

Catchment area

The 83.4 km² catchment area of ​​the Halch is located in the area of ​​the municipality of Halch in the districts of Buching , halch and Eschenberg . Its larger south-eastern part lies in the Ammergau Alps , its smaller north-western part in the flatter and predominantly open subalpine young moraine region, where pasture and meadow management dominates over agriculture.
