Blue Green Algae Toxins Detected at Lake San Antonio; Danger Warning Issued As Lake Goers are Advised to Stay Out of the Water Until Further Notice; Take Other Safety Precautions

 

County of Monterey Public Works, Facilities and Parks will be posting “DANGER” level warnings at Lake

San Antonio North and South Shores. The danger level posting will remain in place until additional test

results indicate the lake is safe for recreation activities.

Prior to every major summer holiday weekend, water testing at Lake San Antonio is performed by the

California Central Coast Regional Water Quality Control Board. In anticipation of the July 4th Holiday

weekend, samples of Lake San Antonio North and South Shore surface water were collected on June 21,

2023. Test results were received by Monterey County on June 28, 2023. Unfortunately, cyanotoxins (toxins

produced by blue-green algae) were detected at both sampling locations, which requires that a “DANGER”

level warning to be issued for the entire lake.

The Regional Water Quality Control Board advises the following:

• Stay out of the water until further notice.

• Do not let pets and other animals drink or go into the water or go near the scum.

• Stay away from scum, and cloudy or discolored water.

• Do not eat fish or shellfish from this water.

• Do not use this water for drinking or cooking. Boiling or filtering will not make the water safe.

Lake San Antonio Closed Due to Large Scale Fish Die Off; Number of Fish Impacted is Increasing and Reason for Die Off Remains Unknown

July 9, 2024- Out of abundance of caution for public health, County of Monterey Parks is closing the Lake San Antonio facility due to a large-scale fish die off from an unknown cause. On July 5, 2024, Parks staff noticed that dead baitfish, mostly shad, began washing up on the shore around Lake San Antonio and immediately contacted California Department of Fish and Wildlife (CDFW) to report the situation. At that time, the CDFW fisheries biologist stated the fish die off was most likely due to the high temperatures and low dissolved oxygen level in the water and that the situation most likely did not present a risk to the public. Parks staff also contacted the Water Resources Agency (WRA), State Water Resources Control Board and Environmental Health Bureau.   Unfortunately, the fish die off has continued with larger species such as bass, catfish, crappie, carp, and trout being impacted. Attached photos include a 3–4-pound bass.   CDFW, WRA and EHB are working together to try t...
