A waterfront city in San Luis Obispo County
Morro Bay is a waterfront city in San Luis Obispo County, California. As of the 2010 census, the city population was 10,234, down from 10,350 at the 2000 census.Located on California’s central coast approximately twelve miles north of San Luis Obispo on Highway 1; is also the name of the large estuary that is situated along the northern shores of the bay itself. The larger bay on which the local area lies is Estero Bay, which also encompasses the communities of Cayucos and Los Osos. The town’s most striking feature is Morro Rock, a 576 foot high volcanic plug which stands at the entrance to the harbor. Originally it was surrounded by water, but the northern channel was filled in to make the harbor. The Rock, as locals call it, was quarried from 1889 to 1969. Public access is restricted, as the rock is peregrine falcon reserve. However, the area around the base of Morro Rock can be visited. Every few years, someone is caught trying to climb the rock. Climbers risk more than fines or jail time as the rocks that form Morro Rock are loose and fall down regularly. The base of Morro Rock is littered with fallen boulders. Morro Rock is one in a series of similar plugs that stretch in a line inland called the Nine Sisters. It is possible that the landscape moved over a volcanic hot spot through the ages.
Morro Bay is a natural embayment with an artificial harbor constructed by the U.S. Army Corps of Engineers. It is the only all-weather small craft commercial and recreational harbor between Santa Barbara and Monterey. Morro Rock was originally surrounded by water, but the Army built a large artificial breakwater and road across the north end of the harbor, linking Morro Rock and the mainland. Some of the rock used for this and for the artificial breakwaters was quarried from Morro Rock itself. Other rock was imported by barge from Catalina Island. The bay extends inland and parallels the shore for a distance of about 4 miles south of its entrance at Morro Rock.
Only relatively small craft are capable of passing the harbor channel. A large natural sandspit, augmented by breakwaters, protects the harbor from the Pacific Ocean to the west. At its northern end, remains of a bridge that used to connect the shore with the sandspit can be seen. Morro Bay Harbor’s channel silts up and must be dredged every three to four years. Previously, the Shark Inlet connected the back bay to the ocean. Some have proposed reopening it to slow the sedimentation that is filling up the bay. There has also been work on reducing erosion in the Chorro Creek watershed to reduce the amount of sediment coming into the bay to form bottom layers of bay mud. Chorro Creek is the bay’s largest tributary. It forms an estuary in the back bay between Morro Bay and Los Osos. The second largest tributary, and the only other significant one, is Los Osos Creek, which empties into the far south end of the back bay.

Mariners are strongly urged to seek local advice prior to making use of the channel, especially when whitecaps or wind-blown water is evident or a small craft advisory is in effect, which is very often. The United States Coast Guard regards the harbor as one of the most dangerous in the entire nation, while others put it in the top six on the West Coast of the United States. In 1995, the Army Corps of Engineering deepened and expanded the channel to improve safety. From 1979 to 1987, 21 lives were lost in boating accidents alone. However, many additional deaths have resulted from sightseers and fisherman being swept off the rocks of the breakwater surrounding Morro Rock. They often approach too closely to the waves and are caught off guard when a big wave set comes in. The slippery and jagged rocks only add to the danger. Public access to the breakwater has been revoked and those who venture beyond the signs do so at their own peril. Coast Guard Station Morro Bay operates two small vessels. Limited transient vessel services are available. Yachtsmen may wish to contact the Morro Bay Yacht Club. A public boat launch ramp is available at the far south end of the Embarcadero.
During World War II, there was a U.S. Navy base on the north side of Morro Rock where sailors were trained to operate LCVPs. The breakwater on the southwest side of the Rock was built in 1944-45 to protect the LCVPs entering and leaving the harbor. Soldiers from Camp San Luis Obispo would come to Morro Bay and practice loading into the LCVPs. Many of those men were at Normandy on D-Day.
