The river has supported human settlements since ancient times, with evidence of people living along its banks for thousands of years. Over time, mills and other structures were built to harness the power of the water flowing through the region.

The waterway is navigable by small boats throughout most sections, though hydroelectric installations restrict passage in some areas. The lakes and open sections along the banks provide the easiest access for visitors exploring the area.

The waterway flows through an area rich with archaeological sites that reveal how people have been connected to this system for thousands of years. This ancient relationship between people and water remains visible today in how communities use and value the surrounding landscape.
