According to the Ely Center, it is a restoration project, as the silting up of Lake Valkeistenjärvi has progressed as a result of the lowering of the water level in the past.
Valkeistenjärvi, located in Multia, is being renovated into a habitat for birds. Valkeistenjärvi, located along the banks of Kukontie, is very much swamped, and it was already renovated once twenty years ago.
Now the surface vegetation and the thin layer of peat below it are being removed from the lake with a floating excavator. The goal is to treat an area of \u200b\u200bslightly more than a hectare so that part of the masses to be removed are piled up as nesting islands for the birds.
Most of the material is transported away in the winter. In total, the masses accumulate around 7,500 cubes.
During the previous renovation, the water level was raised by building a bottom dam at the upper end of the stream. The measure revived the bird population a little, but from the point of view of waterfowl, there is still too little water surface and actual open water area, says the ely center. Now the bottom dam is raised so that the lowest water level of the season rises by about 30 centimeters.
Some of the untreated coastal marshes get a water surface as a result of the excavator works, which makes them more suitable as feeding areas for waterfowl.
The Ely Center emphasizes that it is a restoration project, as the silting up of Lake Valkeistenjärvi has progressed as a result of the lowering of the water level in the past.
