Algal bloom leads to local health advisories; most of Clear Lake open to recreation

LAKE COUNTY – Despite ample rainfall and higher lake levels this summer, the blue-green algae that last year proved troublesome for several shoreline areas on Clear Lake has reemerged.


The algae blooms recently have been observed in the same general areas as last year, mainly in the southern sections of the lake where prevailing winds tend to cause localized accumulation of the algae, in the form of a filmy layer or mats on the surface of the water, health officials reported Thursday.


As in the bloom last year, the predominant genera of this blue-green algae bloom is known as lyngbya. The Lake County Health Department and Department of Water Resources said that recent tests of water in Clear Lake have not detected toxins.


Precautionary health advisories have been posted at a few southern beach locations where the blue-green algae has accumulated, per state guidelines that call for the posting of areas where there is visible film or mats.


The affected public areas are currently limited to Austin Park, Highlands Park and Redbud Park, the county departments reported. The majority of the lake remains open for recreation.


Health officials said avoidance of contact with water in the immediate vicinity of algae accumulations is prudent. Because of the potential for harmful substances to be present in dense accumulations of blue-green algae, people and pets are advised to avoid swimming, wading and drinking water in the immediate vicinity.
