Science in Short: Daylighting Delta Data

Once you know how many fish are present in a particular part of a river, including additional details like the time of day and water temperature, what do you do with this information? For decades, Delta researchers have collected millions of similar data points from daily visits to the San Francisco Estuary, not all of which are available or immediately useful. How that information is then translated into a language...

Atmospheric Rivers Intensifying as World Warms: How the West Will Know What’s Coming

In just a few years, tracking the West Coast’s atmospheric rivers by airplane has gone from what one hydrologist called “really wild-eyed stuff” to a Congressionally-funded operation. This Atmospheric River Reconnaissance program, which wrapped up its latest season in March, monitors these increasingly powerful storms as they shoot across the Pacific Ocean and delivers real-time data to National Weather Service forecasters. Knowing when, where, and how hard atmospheric rivers will...

The Complexities of Monitoring Steelhead

For more than two decades, steelhead — listed as federally threatened in 1997 — have been monitored throughout the state. However, until recently that monitoring has been a haphazard affair. Each local jurisdiction has established a different system, using different methods with different degrees of intensity, according to a 2018 study examining monitoring within the Central Valley and its environs. In some areas, primarily the Sacramento River watershed, which drains...

South Bay Trawls Show Fish Like Restored Shores

Twelve years ago, scientists at UC Davis began a survey of the southern end of San Francisco Bay — the Lower South Bay — to see how fish responded to the South Bay Salt Ponds Restoration Project. They discovered an unexpectedly diverse and robust aquatic community and a previously unknown spawning ground for the longfin smelt (Spirinchus thaleichthys), listed as endangered in California and a candidate for federal protection because...

Will Salmon Simmer Again?

After two critically dry years that coincided with Trump-era rollbacks to environmental protections, some iconic Delta fish are closer than ever to the point of no return. Last fall, for the second year in a row, the fall midwater trawl found zero wild Delta smelt, while a coalition of environmentalists and fishermen is asking a federal court to help prevent a repeat of 2021’s near-obliteration of endangered winter-run Chinook salmon....

Gone Fishing

As the weekend dawns and California slumbers, the sportfishers descend, like clockwork, on the banks and waves of the San Francisco Bay and Sacramento-San Joaquin Delta. They carry nets for herring or poles for sturgeon, heavy and light tackle, bloodworms or anchovy or any number of delectable morsels to attract the desired target. They tread industrialized East Bay shorelines and marshy Delta banks, hop aboard sporty six-pack boats for more...
