The Lag Prau Tuleritg is an annual recurring temporary lake a complex hydrological system in landslide -Schutt at Flims in the Swiss canton of Grisons . It lies at an altitude of 1015 m with a seasonally fluctuating level and has no outflow.
phenomenology
The lake falls completely dry at the end of summer. Every early summer when the snow melts in the mountains, more water flows in the underground system and the Lag Prau Pulté , which overflows as a result, supplies the lake near Tuleritg with water via a stream. The Prau-Tuleritg-See lies in an area chamber west of the Cauma lake . Obviously, the lake feeds underground Cauma Lake, which is about 18 meters below, with no inflow. Lake Cauma changes its level by up to 6 meters.
There are several groundwater systems in the Flims region. One of these has water outlets in Lag Tiert, in Lag Prau Pulté and in the Flims bypass tunnel, since a karst tube was cut when it was built. This cutting may have reduced the water pressure in the Karst, and Lag Tiert and Lag Prau Pulté receive less water than before. Since the Lag Prau Pulté feeds the groundwater body of Lake Cauma, this too is now lacking water. With the feeding system into the stream from Pulté to Lag Prau Tuleritg, which went into operation in 2011, the municipality of Flims is adding to the water flow.
Surname
The name refers to the lake as the one at the meadow ( Prau ) with the name Tuleritg in the northern neighborhood above the lake.
Location and surroundings
The lake is located in a basin southwest of the Films Waldhaus district and is completely surrounded by forest. Geologically, it lies in the debris of the Flims landslide . The other three Flims lakes are located in other depressions of this largely wooded, hilly terrain: Lag Prau Pulté, Caumasee and Crestasee .
use
You cannot swim in the lake or it is not very inviting. The water depth is hardly worth mentioning.
