ドーバーズドルファー湖周辺のアトラクション＆必見スポット - トップ12

Spring is the time for predatory fishermen. Pike hunt in the reedbeds and shore areas, along the steep edges. They are best caught in shallow waters with spinners or spoons, and at somewhat deeper depths with wobblers or dead bait. Perch swim in sometimes large schools, usually along the rocky ledges and perch mounds, and can be caught with both artificial bait and bait. Zander are most active during this time of year, hunting in the early evening hours both in the shallow, rocky shore areas and at greater depths. In summer, the predators become increasingly sluggish and move almost exclusively to deeper areas. This is the time for coarse fish, carp, and eel anglers. Roach, rudd, bream, and silver bream, and occasionally tench, can be caught off the reed edges with floats and worms or maggots. The bream sometimes reach a considerable size here. Carp now mainly frequent the shallow bays. Catching them, however, isn't easy. The most effective method here is certainly fishing with a float and natural bait. Some success has also been achieved with corn. The best time for eel is probably late summer. Using worms or bait, it's important to find the right depth and the right night.

The natural area features numerous protected areas in almost all protection categories. Only a small number of areas are designated as true nature reserves, including the Alter und Neuer See bird sanctuary south of Sulzheim-Mönchstockheim. Another larger area is the Dürrfelder and Sulzheimer Wald fauna-flora habitat, which is also one of the largest forest areas within the Steigerwald foothills. The area is also part of the Schweinfurt Basin and Northern Steigerwald Foothills bird sanctuary.

According to fishing results from 1992 and 1993, the lake appears to have a low fish density. According to the study, this is likely due to a lack of food for juvenile fish caused by low zooplankton densities. The following species, in descending order of biomass, are important for fishing: bream, roach, perch, zander, pike, carp, and eel. Other known populations include rudd, silver bream, gudgeon, ruffe, burbot, tench, crucian carp, and mudminnow. There are currently no known recaptures of the vendace introduced several years ago, which would indicate a possible population.

A natural spectacle regularly observed in autumn is flocks of starlings, sometimes numbering in the tens of thousands, which, after spectacular flight maneuvers, seek roosting grounds in the lake's reed belt. Another natural spectacle, this time in winter, is the invasion of sometimes thousands of cormorants, especially during periods of marginal ice formation on the nearby Baltic Sea coast.

The lake's shores, some of which are protected, are breeding grounds for many bird species. Regular breeding birds include white-tailed eagles, bitterns, marsh harriers, goldeneyes, red-crested pochards, teals, tufted ducks, mallards, coots,[3] mute swans, Egyptian geese, greylag goose, Canada geese, great reed warblers, marsh warblers, sedge warblers, reed warblers, great crested grebes, herring gulls, black-headed gulls, and cuckoos. The lake is also an important moulting site for tufted ducks.

A reed belt is present along large parts of the shoreline. Common reed is the dominant species there. The broadest reed beds are located on the western side of the lake, while the southern side is a silting area dominated by various floating-leaf plants. A 1991 survey identified 18 reed species and 14 submerged species. A scientific study classified the lake as eutrophic. Consequently, the water is murky and mostly colored by various algae.

The lake lies in a typical young moraine area in the Probstei region. During the Ice Age, tongues of ice advancing from the north deepened the area of today's lake. Its shape was preserved by dead ice after the glaciers retreated. The terminal moraine of the Selent ice margin still exists in the south of the lake. The lake is a calcareous polymictic lake, with unstable temperature stratification in large parts. Only in the deep basin does a stable stratification occur in summer.

The lake is approximately 312 hectares in size, making it the thirteenth largest lake in Schleswig-Holstein. It has an average depth of 5.4 m, a maximum depth of 19.5 m, and a direct catchment area of approximately 24 km². The lake is divided into a shallow western basin and a deep eastern basin, separated by Möweninsel (Seagull Island). The lake's only outflow is the Jarbek River, through which approximately seven million m³ of water drain from the lake annually. This stream ends after just 1,000 m in Lake Passad, which drains into the Baltic Sea via the Hagener Au. The most important tributary is the Selkau River, which flows into the lake approximately 100 m south of the Schlesen town limits. The water level is regulated by a weir on Lake Passad.
