In the early afternoon of April 30, for the first time ever, California generated enough electricity from renewable sources to fully meet demand.
Hooray! But there is still a long way to go before meeting the State’s goals for 100% renewable power, or even getting close to that goal.
The achievement was realized on a windy and sunny afternoon in April. If it had been calm and overcast, or evening rather than afternoon, or August rather than April, renewable supply would have been far short of demand.
The growth in renewable power, especially solar and wind, continues. Improvements in energy storage are essential so power generated during daylight hours can be used at night.
And, while all technologies are imperfect, renewable power lessens impacts on the environment. Principally, the shift to wind and solar is intended to reduce reliance on fossil fuels.
There are river restoration projects, however, which will result in relatively small losses of hydropower, including the Trinity (2000), Klamath (very soon?) and the Tuolumne through Hetch Hetchy Valley in Yosemite National Park.

2022 marks a third consecutive dry year in California. Urban water agencies in both southern California and the East Bay are mandating limits for their customers. And Central Valley farmers are making difficult decisions about what crops to grow and what fields to fallow.
Joe Del Bosque grows organic melons in the San Joaquin Valley.
San Francisco, however, has relatively plentiful supplies in storage. Their nine surface reservoirs contain almost the identical amount of water that they did a year ago – more than a million acre-feet and roughly 5 years of supply. (San Francisco also operates two smallish groundwater banks.)
In some dry years, San Francisco’s junior water rights on the Tuolumne River yield almost no supply – the Turlock and Modesto Irrigation Districts get it all. 2022 was different. San Francisco received substantial amounts during the two early season storms that caused high flows on the Tuolumne River for short durations. Had that same amount of water flowed at lower rates for a longer period, none of it would have belonged to San Francisco.
(Water rights on the Tuolumne work like this: Natural flow is measured/calculated on a daily basis in cubic feet per second. For most of the year, the Turlock and Modesto Irrigation Districts get the first 2416 CFS, and San Francisco gets only those flows above that threshold. During the peak snowmelt season from mid-April through mid-June, that threshold increases to 4066 CFS. See below.)
Water rights on the Tuolumne and elsewhere in California can be described as inane and cattywampus.
While water agencies, including San Francisco, do need to operate conservatively to meet the needs of their customers, some argue that San Francisco hoards too much water in dry years.
Whatever level of reliability is warranted, Restore Hetch Hetchy urges San Francisco to invest in system improvements that will replace the storage function of Hetch Hetchy Reservoir and allow Hetch Hetchy Valley to be restored.

Restore Hetch Hetchy has deep historical roots and an inspiring vision for the future.
We promote restoring Hetch Hetchy, Yosemite Valley’s lost twin, to its natural splendor; a majestic glacial carved valley with towering cliffs and waterfalls where river and wildlife run free. Hetch Hetchy can be a new kind of national park, with limited development, an improved visitor experience, shared stewardship with Native peoples, and permanent protection of its natural and cultural heritage for future generations.
We recognize the history of Hetch Hetchy’s destruction, as we build our campaign to realize this vision. twenty years ago, historian Robert Righter said it well when he titled his seminal book “The Battle over Hetch Hetchy: America’s Most Controversial Dam and the Birth of Modern Environmentalism.”
Now we have yet another outstanding book. The University of Exeter’s Laura Smith has just published a compelling, thoroughly researched, treatise on five pivotal writers in American conservation. Ecological Restoration and the U.S. Nature and Environmental Writing Tradition: A Rewilding of American Letters weaves the writings of Henry David Thoreau, John Muir, Aldo Leopold, Marjory Stoneman Douglas, and Edward Abbey into a common thread. Walden Pond, Hetch Hetchy, Leopold’s sand farm, the Everglades and Glen Canyon are different pieces indeed but all bring us closer to the magic of our natural world. Do yourself and Earth Day favor and get yourself a copy.
And many thanks to the author for sharing our inspiration to restore Hetch Hetchy and turn it into a new kind of national park.

The National Park Service, working with Yosemite’s traditionally associated tribes and the Yosemite Conservancy, has improved its interpretation of the ongoing legacy of the Indigenous peoples who lived in Yosemite long before it became a national park. The sign below is prominently displayed at the entrance of the Mariposa Grove of giant sequoias. We’d like to see similar signs at Hetch Hetchy and elsewhere in Yosemite.
The new sign at the entrance to the Mariposa Grove should be a model for others in Yosemite. Click here for larger version.
And just last week, the Park Service removed an old sign from in front of the village store that cast Indians in a negative light for defending their land and their families.
Kudos to the Park Service for removing the sign that mischaracterized the Mariposa War. We know better.
We’d like to see a few other Hetch Hetchy related signs as well. We’ve asked the Park Service to work with CalTrans to install a sign on Highway 120 that indicates where Hetch Hetchy is, and that it is another entrance to Yosemite National Park. And we’d like to see extended hours of access to Hetch Hetchy or, even better, access around the clock like it is in the rest of the park – warranting a change to or removal of the sign below.
In recent years, gate hours have been even more restricted than the sign indicates. Why restrict gate hours at all? (Photo: Jennifer Witherspoon)

A key difference between restoring Hetch Hetchy and restoring the Bay Delta is the effect on water supply. Restoring Hetch Hetchy means relocating the reservoir but need not affect supply. Restoring the Bay Delta requires water to flow through the estuary so it cannot be used on cities and farms.
On March 29, the California Department of Natural Resources announced a landmark agreement to balance the water needs of cities and farms with those of the fish and wildlife (especially salmon) that rely on the Bay-Delta estuary and the rivers that feed it.
It is a big deal.
The Memorandum of Understanding, signed by State officials and a plethora of water agencies, is a voluntary agreement intended to replace the resolution to update the Bay-Delta Plan which the State Water Board authorized in December 2018.
Not everyone is content with the voluntary agreement. Environmental and fishing groups were not included in the negotiations, and many believe the plan does not provide the amount of water that fish need. And while some water agencies signed on, others did not – including the San Francisco Public Utilities Commission and other agencies who reply on water diverted from the Stanislaus, Tuolumne and Merced Rivers.
The voluntary agreement does not include as much additional flow for fish as the State Board’s 2018 resolution. The voluntary agreement does, however, include measures to improve riverine habitat (floodplains, spawning gravels etc.) that were absent in the State Board’s resolution (by law, the State Board is only authorized to regulate water flows).
So, the water agencies who signed the agreement have generally agreed to its effect on their supplies, whereas the agencies who have not signed are generally unhappy with how much water they may need to give up. Many environmental and fishing groups contend there will not be enough water to restore populations of native fish.
Notably absent from the officials signing the Memorandum of Understanding are representatives of San Francisco or the irrigation districts who use water from the Stanislaus, Tuolumne and Merced Rivers. Environmental and fishing groups were also not represented.
Governor Newsom praised that plan, calling it a rejection of “old binaries”. Jared Blumenfeld, California’s environmental protection secretary said it would “move us away from ‘water wars’.” Wade Crowfoot, California’s natural resources secretary, added that voluntary agreements “hold promise to improve environmental conditions more quickly and holistically than regulatory requirements.”
Crowfoot’s point is well taken. The plan is likely to move forward, whereas implementing the State Board’s resolution would have resulted in piles of lawsuits and may have been delayed for many years.
Still, there will be lawsuits. For many, water policy in the Central Valley is a zero sum game – supplies are either diverted to cities and farms or allowed to flow naturally through the Bay-Delta estuary for environmental benefit. It is an either-or situation. Advocates of the two sides have been battling for decades and are not likely to stop now or anytime soon.
Restoring Hetch Hetchy is different.
Restore Hetch Hetchy has always insisted that San Francisco be kept whole with respect to its water supply. We urge San Francisco to pursue system improvements so Hetch Hetchy Reservoir can be relocated without any loss of water supply or electric power production.
Hetch Hetchy, Yosemite Valley’s lost twin, can then be returned to its natural splendor; a majestic glacial-carved valley with towering cliffs and waterfalls where river and wildlife run free. Hetch Hetchy can be a new kind of national park, with limited development, an improved visitor experience, shared stewardship with native peoples, and permanent protection of its natural and cultural heritage for future generations.
And nobody need lose a drop of water.
