The 2014 Wildflower Triathlon had to accommodate the extremely low water level by moving the swim portion two miles from where it is traditionally held.

In June 2015, the Monterey County Board of Supervisors announced it would close the camping and other facilities at Lake San Antonio effective 1 July 2015, due to costs and falling attendance.

The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Lake San Antonio based on levels of mercury or PCBs found in fish caught from this water body.

Most campers prefer North Shore over Lake Nacimiento (Located 9 miles south) because of the much larger campsites, and ability to camp on the water's edge.

Lake San Antonio is a popular winter habitat for the bald eagle, the national symbol of the United States.

Monterey County Parks provides tours in January and February for visitors interested in viewing the bald eagle in its native habitat.

Due to lower revenues and high costs to maintain the facilities, the Monterey County Board of Supervisors opted to close the lake effective 1 July 2015 for the remainder of the summer season.
