Spintik ponds
The Spintik ponds are two Carinthian ponds that lie on the ridge between the Wörthersee and the Keutschacher Seental . The area around the two ponds has been a nature reserve since 1959 .
The two ponds were created from artificially dammed wet areas. They lie in shallow hollows made of ground moraine material that lies above the Upper Eastern Alpine old crystalline. Inflow and outflow take place through a notched valley . The lower pond is partially surrounded by meadows and fields, the upper mostly by forest and bogs .
Lower Spintik Pond
The northern Lower Spintik pond is at an altitude of 560 m above sea level. A. and is 1.68 hectares . Its volume is 22,000 m³, its maximum depth 2.5 m, the average depth 1.4 m. It is almost rectangular and its only inflow is the outflow from the Upper Spintik Pond.
Upper Spintik Pond
The southern Obere Spintik pond is 571 m above sea level. A. and is 7.6 acres. Its volume is 132,000 m³, its maximum depth around 4 meters, the average depth 1.7 m. It is irregularly shaped and has a small central part and three bays. The tributary is a small brook about 300 m long coming from the west. The drain flows into the Lower Spintik pond.
Waters
Both ponds warm up very quickly in spring because of their shallow depth and can reach 20 ° C in May. However, the temperature fluctuates greatly. In winter they can be frozen over from December to March, the ice cover often reaches 40 cm.
The color of the water is brownish. This is due to the surrounding moors. The lime content is very low. In terms of phosphate content, they are classified as mesotrophic .
In the phytoplankton , blue-green algae , golden algae , armored flagella algae and ornamental algae predominate. Of the animal plankton, the plankton cancer Acanthodiaptomus denticornis , which otherwise only occurs in high mountain lakes, should be mentioned.
The bottom of the ponds is made of peat mud. Underwater vegetation includes spawning herbs , milfoil , water lilies and water hoses .
Bank vegetation and surroundings
Most of the bank is made up of black alder trees. Where they are missing there is a narrow belt of reeds. Inland, stiff sedge with beaked rushes join. The mud horsetail is present over a large area . Fever clover , swamp blood-eye , yellow loosestrife , swamp hairline and water mint also occur in its stocks .
Swinging turf made of mud sedge also occurs. Some of them are covered with raised bogs made of peat moss. The round-leaved sundew and the Scheidige cottongrass also occur on these .
Pipe grass meadows dominate on the alternately moist soils that lead to the high forest .
Nature reserve
The Spintik ponds were placed under nature protection in 1959 (LGBl. 18/1959). The Spintik-Teiche nature reserve covers 79.5 hectares in the communities of Maria Wörth and Keutschach am See . The Rauth nature reserve connects to the west and the Schrottkogel nature reserve to the east .
