Lake Info
Lake Pielinen
Pielinen is more than 90 km long and up to 30 km wide in a north-eastern direction, and is the fourth largest lake in Finland by surface area. It is characterised by towering dunes on the shores and large open lake shelves. The lake covers an area of 89 420 hectares, or 894.2 km². It is 104 kilometres long and 30 kilometres wide. It has a volume of 8 999 million m³, or 9.0 km³. The average depth of the lake is 10.1 metres and the maximum depth is 61 metres. The deepest point is near the island of Paalasmaa.
Islands
Pielinen is fragmented by archipelagos, so large ridges can be found in different parts of the lake. There are an estimated 1491 islands in the lake. They cover a total area of 14 715 ha, which is about 14.1% of the total area of the lake. Of these, 26 are larger than a square kilometre, 288 are larger than a hectare, 1 103 are larger than an acre and the remaining 74 are smaller than an acre. The most notable of these are Paalasmaa, Kynsisaari, Porosaari, Iso Ristinsaari, Koveronsaari, Hattusaari, Satjanko and Kelvänsaari.
Lake parts
At the northern end of the lake are two parts of the lake that are separate from the main lake basin. Lautiainen, which is 8.7 km long and 2.7 km wide, lies behind Aksonalmi in the Porokylä village of Nurmes, and Nurmesjärvi, which is only 2.1 km long, opens up just behind Mikonsalmi to the east of the centre of Nurmes. The Saramo River flows into Ylikylä at the bottom of Lautiainen.
Lake Kuokkastenjärvi is a separate part of the lake, which starts at Aronsalmi and is 8.1 km long and 1.7 km wide. It is located at the north-western end of the lake. The Kuokkastenkoski power plant is located in the Pöyhölänjoki River, which flows into the Lahdenpohjuka. The centre of the town of Lieksa is located on the shore of Mönninselkä. The Lahdenboden is 14.5 km long along the main axis of the lake, but its mouth opens perpendicularly at Mahonselkä, which is 5 km wide and 6.5 km deep. Jauhiainen is a lake-like bay on the eastern shore behind the village of Vuonislahti and a strait over 20 metres wide. It is 5.1 km long and 2.0 km wide.
At the south-eastern end of the lake, at the mouth of the Pielis River, is the Rahkeenvesi, which lies behind the Laiskan stream at the Uimaharju bridge. The lake is 4.6 km long and 1.4 km wide. Rukavesi is also located at the south-eastern end of the lake, between Laukkalansaari and Uimaharju. It is 8.0 km long and 3.8 km wide. Eight kilometres southeast of Juuya is Nunnanlahti, which is sheltered behind the 3.6-kilometre-long Vinkarinniemi. At the bottom of the bay is Nunnanlahti. A special and sheltered part of the lake is Höljäkkä, where the Retusaari and its archipelago cover an eight kilometre long and narrow area behind the village of Kopraksi.
