Goolwa Barrage Travel Guide

The Goolwa Barrage is more than just a concrete structure; it's a critical component in managing the health of the River Murray and the surrounding ecosystem. Constructed in 1935, the barrage serves as a physical barrier, preventing the intrusion of saltwater into the freshwater Lake Alexandrina and Lake Albert. This is essential for maintaining a stable water supply for irrigation and domestic use.Visitors can take a leisurely walk along the top of the barrage, enjoying panoramic views of the lower River Murray and Hindmarsh Island. The area is a haven for birdlife, with numerous species inhabiting the surrounding wetlands. Keep an eye out for the playful seals that frequent the area, often seen fishing or basking in the sun. Informative signage provides insights into the barrage's construction and its role in regulating the river's flow.The barrage is one of five that make up the Goolwa Barrages. These structures were authorized in 1931 to address salinity issues in the lower River Murray. The project, undertaken by South Australia's Engineering and Water Supply Department, was completed in 1940. The construction aimed to stabilize the river level for upstream irrigation and pumping, a necessity following the development of large irrigation schemes.While the seals have been seen more frequently in the area since 2007, they are native to the region. The seals, often Long-nosed fur seals, were hunted to near extinction in the 19th century, but their numbers have since recovered. Today, the Goolwa Barrage offers a unique opportunity to observe these marine mammals in their natural habitat.
