First Sausage Sizzle of the Year

it's that time of year again!

Cuppa: hot chocolate from a whistling kettle (the best kind)

Dinner: square sausage in a morning roll!

Sometimes, you don't want to go out, so you snuggle down. Other times, you don't want to go out, but you know you need to.

Dams are fun, aren't they? They water's really high just now. We'll be glad of that if it's a dry summer. It's choppy tonight, and the waves are breaking over the spillways

I'm so confused about what time of year it is, because of the early Easter and having been abroad. I keep thinking it's later than it is, and feeling lost and disoriented. My sense of being grounded depends so much on the seasons, I needed some time outside to reset my clock, in among the birdsong and the bleating of the lambs.

Conservation and environmental justice groups filed a legal challenge today to the largest reservoir project approved in California in decades. The Sites Reservoir would harm the Sacramento River ecosystem, threaten already imperiled fish species, and release greenhouse gas pollution, today’s lawsuit says.

Sites would require the construction of several enormous dams and two 3,000-foot-long and 23-foot-wide tunnels. It will cost an estimated $4.4 billion.

Proposed for a rural area about 80 miles northwest of Sacramento, the project would store about 1.5 million acre-feet of water, or nearly 490 billion gallons. To achieve this capacity, the reservoir would divert large quantities of water from the Sacramento River system, which is home to federally protected salmon and steelhead.

Most runs of Sacramento River salmon are imperiled and all are declining. Sites would reduce flows in the Sacramento River when salmon are migrating.

“The Sites Reservoir project will cause much environmental harm, which falls on the public, and a small amount of good, which primarily benefits the project investors,” said Ron Stork, senior policy advocate at Friends of the River. “Among other harms, the reservoir will be a major greenhouse gas emitter. A recent analysis estimated that Sites would emit the equivalent of 80,000 gasoline-powered cars each year.”

Water Levels Are Low in Major California Reservoirs

July 26, 2022 capacity compared to historical averages

Two of what should be the California’s wettest months, January and February, brought almost no precipitation this year, and water levels at the state’s major reservoirs are low compared with historical averages.

Reservoirs are a solution to the tremendous variability in natural water supply, but what happens when they stop filling up?

People use water at more or less a constant rate and yet, mother nature supplies it in unpredictable sloshes of rain or snow that can change with the seasons and often have considerable dry periods between them. If the sloshes get too far apart, we call it a drought. And at least one study has estimated that the past two decades have been the driest period in more than a thousand years for the southwestern United States, leading to a so-called “mega-drought.” (Source: https://www.npr.org/2022/02/14/108030...)
