context: The water is 23 kilometers long and 13 kilometers wide [1]. The lake covers an area of ​​6616 hectares or 66.2 square kilometers, which is 62% and 38% respectively between Ruovesi and Paloselä. Its total coastline, including the islands, is 321 kilometers. There are a total of 242 islands. The lengths of the coastline and the number of islands are almost equally distributed between the two lakes. In contrast, the total volume of lake basins is 446 million cubic kilometers, or 0.44636 cubic kilometers. Of this, 82% for Lake Ruovesi and only 18% for Paloselä, as the average depth of Ruovesi is only one third of that of Paloselä. [2]
