Most of the approximately 20,000 residents of our municipality live near the Ångerman River or its tributaries, the Fax and Fjällsjö Rivers. The settled land in our area is called “Ådalen” and is full of the steep, sandy river banks between the river and the surrounding forests that characterize Sollefteå.
Since the distant past, the people of the valleys above Sollefteå have used the word Ådalen (river valley) to describe their area. Today, this term applies to the area around the Ångerman River from Junsele and down to the sea. The municipalities of the lower parts and mouth of the Ångerman River are closely linked. The sediment carried by the river increased the fertility of the land along its banks. Forestry, log floating, sawmills and pulp mills created a unified labour market.
A nipa is a steep, sandy river bank that results from a river digging itself deep into the sediment it deposits.
More than 23,000 years ago, all of Scandinavia was covered by glaciers. As the climate became warmer, the ice began to melt. Later, the valley and delta with all its sediment and sand began rising from the sea. As the land rose, the river dug itself into its own sediment. This led to steep river banks and a unique landscape. This special geographical formation is called a nipa.
The approximately 40 kilometres of the Ångerman River from the Sollefteå power plant to the sea is the last stretch of river with natural ripas.
