Federally endangered coho salmon and threatened steelhead trout respond to the rains, which create runoff and are a natural invitation for the fish to begin swimming from the oceans upstream into creeks to spawn in the Lagunitas Creek watershed. In December — a key month for coho migration — just .31 of an inch of rain fell in the county as measured by the Marin Municipal Water District.
Rain hit the Bay Area hard early Tuesday morning, and little is expected to change for most of the week. “A cold front is moving across the region this morning,” said Roger Gass of the National Weather Service in Monterey
Sonoma County is launching a public outreach campaign this week to gather input on its nascent groundwater regulatory system that could eventually levy new costs on thousands of residents throughout the region.

If you imagine the San Francisco Bay as a bathtub, sea level rise means the bathwater is rising. A new study published today in Science Advances finds the tub is sinking too, and in some places, more than others.
Major parts of San Francisco Bay’s shoreline are slowly sinking, a new scientific study has found, dramatically increasing the risk of billions of dollars of flooding in the coming decades as sea level rise continues due to climate change.
When it rains, it pours — and that has San Francisco water officials looking into charging property owners a new “storm-water fee” to help with the upkeep of the city’s aging sewer system. … A state bill signed into law by Gov.

For generations, hikers, bicyclists and motorists looking for a sweeping view have ventured up the Bay Area’s most distinctive and popular peaks: Mount Diablo, Mount Tamalpais and Mount Hamilton. Now there’s a new member in the popular summit club.
The splendor of Ring Mountain was on full display Monday as sunshine lit up a froggy marsh amid resurgent native growth — all elements of a preserve boosted in recent years by new funding. “Ring Mountain is an incredibly beautiful place,” said Max Korten, Marin County Parks director.
The Chronicle archives overflow with photos documenting the downstream journey of Hetch Hetchy’s water — an engineering marvel that feeds power stations and fills reservoirs. So here’s a follow-up to our previous column on O’Shaughnessy Dam and Hetch Hetchy Valley.
Ross Valley’s controversial flood fee was hiked 3 percent Tuesday, helping pay for a public relations campaign smoothing the waters for projects that will turn key park areas into flood retention basins.
Healdsburg Mayor Jim Wood is a dentist who believes in the effectiveness of fluoridated water in combating tooth decay. But he won’t be writing the argument against a November ballot measure to remove fluoride from the city’s water.
From the San Jose Mercury News, in a commentary by Richard Santos:
