lake porkuni

I am Dutch and living in Porkun about 250 meters from the lake. In summer time I swim and sail at the lake.You only can sail with a movable sword, because there are a lot of plants in the undeep parts.One other problem is the fact, that the lake is sometimes totally empty. Once in the 5 to 10 years.The lake is very quired and you are not allowed to have a motor boat in the water.All kind of birds and animals are living in the area.Beavers are sometimes damaging the trees totally.It is never crowded and the water is cristal clear.
