The Sprockfitz is a lake about one kilometer northwest of the village Feldberg in the municipality of Feldberger Seenlandschaft in Mecklenburg-Western Pomerania . With the surrounding forest and grassland areas, the lake has been designated as a Sprockfitz nature reserve since 1957 .
Depending on the water level, the lake is about 88.4 to 94 m above sea level . For a long time the fluctuating water levels were thought to be mystical. It was not until the 1990s that BONITO eV, a hydrographic-biological working group, succeeded in unraveling the secret on behalf of the Mecklenburg-Western Pomerania National Park Authority.
The catchment area is about 8 km². The tributary is formed by the only occasional water-bearing ditch, which rises from springs on the arable land between Lüttenhagen and Weitendorf. When there is little rainfall, the Staugraben seeps into the sandy subsoil behind the Staugraben Bridge ( Thurow – Feldberg railway line ). If he carries 70 m³ of water into the Sprockfitz during the day, it maintains the water level; if it dries up, the water level drops by six millimeters per day, since the Sprockfitz only protrudes between 1 and 2.5 meters into the groundwater at its deepest point and its basin is sandy.
The ditch can also record 11,700 m³ measured during the day. This then means a drastic increase in the water level. The reservoir water then makes up about 87.7% of the total water input. The rest comes from direct precipitation and other water inputs.
Since the extreme fluctuations in water level due to the seepage and collection in the ground are greatly delayed in relation to the precipitation events, the Sprockfitz was long considered a mystical lake.
