Joel Ledesma appointed deputy director of the State Water Project

From the Office of the Governor:

Joel Ledesma, 49, of Sacramento, has been appointed deputy director of the State Water Project at the California Department of Water Resources.

Pyramid Lake Algal Bloom Now at ‘Caution’ Level; Toxin Level Lower than Last Week

From the Department of Water Resources:

The Department of Water Resources (DWR) has detected a reduced amount of microcystins at Pyramid Lake’s Vaquero Day Use Swim Beach. The level now warrants a “Caution” to swimmers rather than the “Warning” that was issued at the lake on July 7. While swimming is now allowed, all recreational users are still urged to avoid direct contact with blue-green algae (cyanobacteria) in Pyramid Lake in Los Angeles County.

Water from the beach at the Vaquero Day Use Area was tested using a field test kit on July 6 and showed a reading of 10 micrograms of microcystins per liter, a level that prompted a “Warning” health advisory and the closure of the swim area. However, laboratory testing of a sample taken on July 11 at Vaquero Swim Beach found 1.13 micrograms/liter, a level that prompts “Caution” signs to be posted.

The Vaquero Day Use Area remains open for picnicking and shoreline activities, and the swim beach has been reopened; swimmers should avoid contact with blue-green algae. A “Caution” advisory issued last week remains in effect for the entire lake.

Bloom conditions can change rapidly, and wind and waves may move or concentrate the bloom into different regions of the lake. “Caution” signs have been posted at locations around the lake.

Silverwood Lake Algal Bloom at ‘Warning’ Level; No Swimming Allowed, Public Should Avoid Water Contact

From the Department of Water Resources:

The Department of Water Resources (DWR) has issued a “warning” advisory for Silverwood Lake’s Sawpit swim beach and Cleghorn swim beach due to the presence of blue-green algae (cyanobacteria). (See Statewide Guidance on Cyanobacteria & Algal Blooms on page 2.)

While the lake remains open to boating, the Sawpit and Cleghorn swim beaches are closed to swimming, and signs have been posted warning the public against swimming at those locations. The public is urged to avoid direct contact with visible algal blooms and mats wherever they occur. Silverwood Lake is in San Bernardino County.

The recommendations are based on the potential health risks from blue-green algae. Water sampled in the Sawpit swim area contained approximately 6.1 micrograms of microcystins per liter (µg/L), a concentration just above the “Warning” action level of 6.0 µg/L.

Bloom conditions can change rapidly, and wind and waves may move or concentrate the bloom into different regions of the lake.
