Historically, Saudasjøen arose as a seaside resort near the small farm of Sauda and it became industrialized in the 1800s. The municipality was incorporated in 1838 and the village of Saudasjøen became its administrative centre (a position it held until the early 1900s when it was moved to Sauda. The small village is an important industrial location, especially in the field of metallurgy. Merchants settled around the quay at the old seaside resort and there were also a number of hotels and cafes in the area including the Sauda Fjordhotel and the Sauda Skisenter. The municipal high school was located here until 1989.
