Until the early 1900s the Val Grande and Val Pogallo were an important source of timber and the river was used to transport the trees felled by means of
log rolling. The San Bernardino provided a source of
hydropower for the factories which were built along its course and its water was employed in the bleaching processes of the adjacent
textile factories. In 1892
Carlo Sutermeister, an industrialist of Swiss origins, constructed the first Italian
hydroelectric power station capable of distributing electrical power; it supplied the inhabitants of Intra, Pallanza and other places in the area as well as the factories nearby. Subsequently the power plant of Rovegro was built and today there are three power stations in use on the river. == Recreational uses ==
