Abstract		The River Krka is a slow flowing karst river with an extended underground hydrological net. The total length of the river is 92 km. It is called a „green river" due to great abundance of macrophytes from its source to the outflow into the River Sava. Travertine cascades, blocks and concrete dams in the riverbed influence the flow. The river channel is mostly shallow. The watershed is a mosaic of agricultural and natural landscape with some industry. Abundant aquatic flora presented by 39 macrophyte species was determined in the river. Among submersed macrophytes Potamogeton nodosus, Ceratophyllum demersum, Myriophyllum spicatum, Potamogeton filiformis and Najas marina were abundant. Species composition changed significantly from Novo mesto downstream as a consequence of lower water quality. Najas minor that was only found in one stretch, has the status of a wlnerable species in Slovenia.
