Flaten 3.31

Flaten is a lake in southern Stockholm, Sweden, located just north of Lake Drevviken. The name is also used for the surrounding area and the nature reserve created there in 2007.Flaten has the best water quality of all lakes around the Swedish capital and is highly popular for bathing and angling. The surrounding area is dominated by forests, with allotment-gardens and some industrial activities located north of the lake. Algal bloom occasionally occurs in spring.Catchment areaThe undulating wooded grounds of the catchment area are considered as of significant natural value and, through the location within a nature reserve and proximity to Stockholm, also of significant recreational value. A scenic ravine is found by the southern end of the lake while most nearby settlements are located north of it. The arrea is used for various open-air activities including walking, bathing, camping, canoeing, and fishing. The area is a fine example of the fissure-valley landscape prevalent in the entire Stockholm County, featuring elevated flat rocks separated by valleys with oaks and spruces, some of which can be several hundreds years old. In the catchment area are also three allotment-gardens and the residential area Skarpnäck. A bathe is located on the eastern shore. The catchment area for groundwater is much larger than that for stormwater.
