Drought Contingency

By Jacoba Charles Motivated by the recent drought, local water agencies have formed an unprecedented partnership aimed at reducing the impact of future dry spells. The Bay Area Regional Reliability partnership consists of eight of the region’s larger water districts. “For the first time in the history of water deliver in the Bay Area, the water utilities are talking about how to assist each other when there is a shortage.”

Choice Mountain Parcels Help Protect Bay

By Nate Seltenrich John Muir Land Trust announces one of its largest-ever purchases, the 604-acre Carr Ranch located squarely within San Leandro Creek’s 50 square-mile watershed. Similar conservation targets exist across the Bay Area, particularly on the outskirts: Sprawling, undeveloped, privately owned parcels whose protection sends a variety of benefits cascading downhill towards the bay.

EBMUD Experiments With Pipe Replacement

Download June 2016 ISSUE PDF EBMUD Experiments With Pipe Replacement By Nate Seltenrich On average, underground water distribution pipes can last about 100 years. The East Bay Municipal Utility District (EBMUD) owns and maintains roughly 4,200 miles of them. And it replaces about ten miles per year. At that rate it would take four centuries to replace the whole system: an approach one could charitably call unsustainable even if all the pipes were brand-new today. But parts of EBMUD’s system, cast-iron pipes...

Keeping the Salt Field at Bay II

After four of California’s driest years on record, the rain we’ve gotten this winter is hardly a drought buster. But it’s still a relief. Just a year ago, our “wet” season was so dry that state water officials panicked. Major reservoirs were drawn way down, and record-low snowpack would limit replenishment to a trickle. Water managers worried about the hot, dry months. Would reservoirs still hold enough for freshwater releases to keep saltwater from pushing deep into the Sacramento-San Joaquin...

Pivot or Pirouette?

DOWNLOAD September 2015 ISSUE PDF Pivot or Pirouette? By Ariel Rubissow Okamoto and Lisa Owens Viani 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...

No Scapefish in Drought Wars

DOWNLOAD June 2015 ISSUE PDF No Scapefish in Drought Wars by Joe Eaton According to the Biblical book of Leviticus, the ancient Israelites designated a goat to bear the weight of their sins. Nowadays, the scapegoat is not required to be a goat. When it comes to assessing blame for the worsening California drought, a scapefish will suffice. Some media outlets, notably the Wall Street Journal in a recent op-ed piece, point to the hapless Delta smelt as a culprit...

Filling Up on Empty

DOWNLOAD June 2015 ISSUE PDF Filling up on Empty by John Hart “We are sucking our aquifers dry,” the headline reads. Could this be a good thing? The bad effects of declining groundwater levels are known: land subsidence, the cost of pumping from deeper wells, the drying up of surface springs and streams. But there is a potential gain as well. Using up one resource, the water stored under the ground, we are creating another: storage space far greater than any...

Shifts in Selenium Spikes

DOWNLOAD JUNE ISSUE PDF Shifts in Selenium Spikes By Ariel Rubissow Okamoto USGS scientists headed up river this June to see whether two Asian clams had also headed upstream with the drought. When there’s less fresh water flowing out to sea, salty ocean water intrudes inland, and changes the distribution of these pesky invertebrates. Potamocorbula like it saltier than Corbicula, and usually hang out in the Suisun Bay region. But scientists suspect drought conditions may have changed all that, and...

Keeping the Salt Field at Bay

DOWNLOAD MARCH ISSUE PDF Keeping the Salt Field at Bay by Ariel Rubissow Okamoto As the dry, warm days went on and on and on this winter, two guys intimate with California’s Sacramento San Joaquin River delta shifted gears. One reassigned staff from flood to drought response, and the other lay awake at night imagining barriers across various slough openings. By early February, some Sierra reservoirs were so low, and so close to “dead pool” level, that the water projects...
