An interesting habitat due to the damming of the Isar.

The Goben sub-area encompasses a valuable section of the Isar floodplains north of the Isar, between Goben and Harburg. The area is bordered by the Isar dams to the south and a backwater dike to the north, thus largely cutting it off from the river's dynamics. Nevertheless, large, structurally rich riparian forest areas and oxbow lake complexes with numerous rare and endangered animal and plant species can still be found here. Furthermore, the sub-area is home to an extremely valuable burn area. A burn is a dry, open area in an otherwise moist riparian forest that developed on a gravel deposit. High-quality calcareous dry grassland is found here. Source: https://www.wwa-la.bayern.de/projekte/isar_life/projektgebiet/index.htm

Rosenau alluvial fan > a geotope (excerpt from the Bavarian Environmental Atlas) The Rosenau alluvial fan is a flat, Holocene gravel cone that lies only slightly above the surrounding terrain, but has hardly any soil cover and is clearly separated from the surrounding agriculturally used floodplain areas in terms of vegetation (poor grassland). The gravel cone probably belongs to older Holocene gravel sequences that were no longer reached by later floods. Part of the gravel body is disturbed by the railway line and old gravel pits. https://www.umweltatlas.bayern.de/standortauskunft/rest/reporting/sb_geotope/generate?additionallayerfieldvalue=279R006

Due to the weir system and the run-of-river power plant, the Isar is dammed up to form a large reservoir. The dyke system offers a wonderful view over the dammed river, which is also a real paradise for birds.

The Isar Cycle Path runs on a fairly good, varied surface, ranging from fine gravel to asphalt, and offers repeated beautiful views of the Isar River. Between Dingolfing and Landau, in addition to the historic Isar bridges, you can also see the river's renaturalization, Isar reservoirs, and weirs. You can also admire sights such as the Widder (Widder Rock) and the "Wachsender Felsen" (Growing Rock).

Definitely worth seeing and not for nothing one of the 100 most beautiful geotopes in Bavaria and a station for Bavaria explorers. The "Growing Rock" from Usterling is almost 40 m long and 5 m high and is the largest stone channel in Germany.
