I’ve only been following this chart for a couple of years, but this is the first time all of the reservoirs shown in it have been above their historical average. A lot of them are also fairly close to their maximum capacity. It would be nice if this trend continues for a few years. I’m tired of drought conditions. We still conserve water; I hope everyone in California does. Actually, I hope everyone, everywhere is thoughtful about water usage.

Currently, the sun is shining brightly through my home office window, as we’re enjoying a short respite from the deluge we’ve been experiencing. Here in SoCal there hasn’t been quite as much moisture, but the central and northern portions of the state are getting hammered. The table below shows just how dramatically our fortunes have improved since a year ago and, particularly, in just the past week. There’s more rain in the forecast and we’ve still over two months to go in our traditional rainy season.
People like Pat Robertson, and others of his “deep” religious conviction are quick to claim “The Lord” is punishing us when bad things happen. Perhaps they should consider recognizing, if that is the case, then we must conclude God is now rewarding California for rejecting Marmalade Mussolini last November. Surely The Lord is even-handed in both punishing and rewarding us for our aberrant, as well as our compliant, behavior.
To appreciate just how much our conditions have changed, here’s a screenshot of the State’s major reservoirs. Note how many are near or above their historical average. This doesn’t translate directly into replenishment of our depleted water table but, with an increased snowpack and more precipitation on the way, we’re at least moving a long way toward normal conditions. I expect an awful lot of people are going to continue their water conservation efforts regardless of this reversal in our fortunes. Californians are recognizing how precious fresh water is, and how easily it can be hard to come by if we continue using it unwisely.
So . . . I finished taking out the trash, garbage, and recycling materials to the curb and, as is my wont, I took to the kitchen sink to wash my hands. Because I’m far more acutely aware of our water use due to the drought, I ended up washing them with cold water; I just didn’t want to let the water run long enough to get hot.
That got me wondering about how much water could be saved if we had instant water heating. I did a little research into tankless water heaters and quickly found out how little the technology seems to have progressed in the last 10 years or so. Most articles I came across suggested the break-even point for installing one that was reasonably efficient/effective would probably exceed your lifespan.
In the process, I came across figures for the number of gallons of water an average household runs down the drain while waiting for the hot water to push out the cold that’s in the pipes between the sink/tub/shower where it’s going to be used. The figure I came across is 26 – 29 gallons. I also looked at the US Census to see how many households there are in California. The number of housing units listed, as of 2013, is 13,790,495.
So, taking the number of households and multiplying by the more conservative number of 25 gallons per day down the drain, I determined the following. If we could find a way to heat water directly at the point of use, thereby not wasting that 25 gallons per day, the State of California would save 125,838,266,875 gallons of water per year. As it turns out, that’s a third of one percent of the water in Lake Tahoe. Drop in the bucket, or significant savings? Probably doesn’t matter, unless you’ve got an idea for how to provide on-demand, on-location hot water . . . cheap.
I saw a video yesterday of a dog figuring out how to drink from a device set on the ground. It had to be stepped on and held down, but the dog would stomp on it a few times before finally standing on it to keep the water flowing. It reminded me of one of my favorite stories.
Many years ago, when I first started working at Rocketdyne, we had a couple of buildings on the other side of Canoga Ave. from the main office and factory structure. People were always having to cross the street and there was a controlled crosswalk there for that purpose. I was always amazed to find engineers repeatedly pushing the button (like this dog’s doing) to get the light to change.
I kept thinking – though I never said it out loud – “you know that’s a switch, not a pump.” It might be expected of the dog; but, rocket scientists? Maybe they were accountants.
