About Arroyo Grande Creek, CA

Arroyo Grande Creek is one of the main streams located in San Luis Obispo County. Situated in the Central Coast of California, this creek flows about 22 miles (35 km) directed towards the southwestern portion which starts in Santa Lucia Range until the Pacific Ocean. 

The creek derives its name from its Spanish translation, “large watercourse.” Otherwise referred to as “Roaring Grande,” Arroyo Grande Creek supplies the water for the southern part of San Luis Obispo. 

Arroyo Grande Creek used to experience chronic flooding back in the 1950s. Because of this, the lower 3 miles of Arroyo Grande Creek were channelized in 1959. Surrounding tributaries also benefited and were channelized such as Tar Springs and Los Barros Creeks. The installation of floodgates between Arroyo Grande Creek and Meadow Creek made it easier to control the water flow in the location, keeping the nearby homes protected.
