Tracking Tiny Toxins

San Francisco Bay and the region’s other water bodies have an unfortunate legacy of human pollution. But we’re not the only culprits: beyond the mercury and PCBs, the Bay contains toxins produced by phytoplankton—photosynthesizing microorganisms classified as blue-green algae (also known as cyanobacteria), dinoflagellates, and diatoms. Under conditions still not well understood, these tiny organisms secrete chemicals that can enter aquatic food webs and impact human health. Funded by the San Francisco Estuary Institute’s Regional Monitoring Program for Water Quality and the San Francisco Bay Nutrient Management Strategy, researchers are surveying the Bay for microcystin, from the freshwater cyanobacterium Microcystis, and domoic acid, from the marine diatom Pseudo-nitzschia, and trying to account for their presence in the Bay.

Pivot or Pirouette?

Droughts and water shortages, dry creeks, heat waves, snowpack loss, sea level rise, bigger floods, species at risk, scarcer funding for public works and restoration projects, and California’s ever-growing population—as Jeff Mount put it in The New York Times recently, it’s a frightening, uncertain new world. How are Bay-Delta resource managers responding to these changes? Are we pivoting away from old institutional and decision-making structures that need to change or dancing in circles?

Scaled-Down Plans to “Fix and Restore”

Surprising many observers, Governor Jerry Brown announced late in April that the Bay Delta Conservation Program, which had embraced the new water conveyance popularly known as the Twin Tunnels and a broad program for restoring the complex and heavily impacted Delta environment, was being split into two new entities: Cal WaterFix and Cal EcoRestore. On the restoration side, he announced a more modest goal of 30,000 acres, down from the original 100,000.
