. Since lakes formed the main transport route in earlier times, urban areas are often located on lakeshore, occasionally even on isthmuses or peninsulas, e.g. Varkaus, Savonlinna and Kuopio. The lakes often have extremely convoluted coastlines and consist of several nearly separate stretches of open water (''selkä'') connected by narrow sounds. Thus, they can connect large areas along shores and their hinterlands. Because no set definition of what constitutes a lake and no procedures for counting the number of lakes exist, it has been impossible to ascertain exactly how many lakes the region has. There are, however, at least 55,000 lakes that are at least 200 metres wide. If lake is defined to be a body of standing water larger than 500 square metres, then there are 187,888 lakes in Finland. On average, there are 40 lakes per 100 square kilometres in the district. The lake number density is largest north of the
