Cities, towns, development, farms, ranches take water from the Truckee River – some years taking nearly its entire flow

Wasting away in Reno-will-regret-it-ville

Watering on a hot and windy afternoon wastes 30% of the water

With apologies to Jimmy Buffett, it appears that some Renoites have few qualms about watering during hot afternoons.  Not a good idea now with Truckee River flows soon to reach pitifully small levels.  But it isn’t a good idea ever.  Why?

Never mind that the local water purveyor, the Truckee Meadows Water Authority (TMWA), says to “Shut your sprinklers off between noon and 6 p.m. from Memorial Day through Labor Day”.  A better reason to water early in the morning (4 am – 11 am) is because it is cheaper and better for your lawn, too.  Watering in the afternoon costs you money because you’re wasting at least 20-30 percent of the water coming out of your sprinklers.  During our warm and frequently windy afternoons a significant portion of your irrigation water goes directly into the air or gets blown off course onto sidewalks and driveways.  Many sprinkler systems already have way too much pressure and spray out fine mists of water that’s even more susceptible to immediate evaporation into the air.  [Click here for some tips on watering lawns.]

So keep the Truckee River flowing through town this summer – and next – by using less water, using it efficiently (no leaks or broken irrigation sprayers or floods down the gutter), and not watering in the afternoon.  You’ll save a little money, and the river and all its critters will thank you.  Really.

Lahontan Cutthroat Trout spawn for first time since 1938

Today the RGJ’s environmental reporter Jeff Delong reported on the successful spawning of Lahontan Cutthroat Trout in the lower Truckee River in 76 years.  The fish dug spawning beds and reproduced in the Truckee River between the mouth of the river and Marble Bluff Dam.

The article tells the story of how we lost this valuable resource largely to the construction of the Derby Dam on the river which diverts a significant flow of the river to the Newlands Irrigation Project.

We can only hope that the river and the fish can now thrive once again in the 21st century.

Conserve now. Don’t wait for TMWA to ask.

Water runs off over-irrigated lawn in Reno

Perhaps you read the editorial opinion published in the RGJ May 27, 2014 by the GM of the Truckee Meadows Water Authority (TMWA – pronounced TUM-WA – now doesn’t that sound nice?).  Therein the GM declared that the severe and continuing drought was absolutely no reason to conserve water here in the good ol’ Truckee Meadows anytime soon.  Astonishing though it is, that is what he said.

Cleverly entitled “Utility set to meet water needs”, he begins by saying that “everyone is talking about the drought.”  But then he asks “Why not ask for more conservation now?”  Then tells us that “TMWA is prepared to meet the water needs of our customers”, that is, without conservation until the river becomes stressed and flow drops below “mandated” levels.  So when should you conserve?  Not now for heaven’s sake!   In other words, use as much water as you want and we’ll let you know when to conserve – wink, wink.  Implied, but not said is, “please don’t conserve water and keep our revenues up.”  Conservation be damned!

The GM softens his conservation-can-wait message with a paragraph about we’ve-been-through-these-challenges-before and drought-is-a-natural-occurence and as-a-desert-based-utility-TMWA-plans-for-dry-years.  

The essence of the message the GM is conveying?  Use as much water as you need and if you feel like it pray for snow next year.

The GM will use “upstream drought reserves” and “groundwater” to meet your needs later – even if you would be more than happy to conserve (and save a little money) right now.

Of course, Reno averages only 7″ of precipitation a year making us one of the driest places on the planet. Never mind that this year we’re under 5″ and the Sierra runoff will be 25% of average in many locales.  Nevertheless, the GM doesn’t think that a 14 year dry spell is any reason to call for conservation of water anytime soon.  Use what you need to.  Never mind that this drought represents one of the worst dry spells for perhaps half a millennia. After all TMWA is prepared for your business.

Wouldn’t it be nice if the GM were more practical?  more thoughtful?  more likely to err on the side of caution?  more like a leader who needs to be honest with 300,000 people who already know that there is a serious drought and are prepared to respond?  Who prefer to see water in the river rather than evaporating on their sidewalk?

Conservation has to be taught every day of the year to remind all of us that every drop of water we use takes that drop of water from our lakes, river, streams, wetlands, and springs and the wildlife that depends on them.  Conservation should be the main thing that TMWA talks about – as a “desert based utility”.  Conservation is more than reporting “water waste”.  It is the way westerners and the environment we all depend on can survive in a changing climate; a climate that is getting both hotter and drier.

Perhaps the GM could lead and call for conservation every day of the year for the simple reason that we live in a desert.

 

Just 14 years ago …

Time has a way of compressing as we get older.  It seems like only yesterday that our water resources in our lakes and rivers were in great shape.  Today, not so much.

At the dawn of the new millennium, Lake Tahoe was at full capacity, the reservoirs on the Truckee, likewise.  The Truckee River was flowing at over 1000 CFS during May and June.  We just didn’t know then that we were at the cusp of a 14 year-long dry spell .  It has taken its toll on Lake Tahoe storage (just 17″ above its rim as of this writing, and almost certain to go below this summer or fall).  Pyramid Lake has fallen many feet in elevation, but what is dramatic is the amount of shore exposed by the receding water in this long-term drought.  As we’ve explained in other posts, we westerners have relied on a repeat of the precipitation patterns for this century as we have for the preceding century and a half.  So far, it’s not working out for us.

Compare these two photos (taken from locations at the south shore of Pyramid Lake in Aug 2004 and this April 2014.  The latter photo is taken from a position which shows the amount of recession Pyramid is undergoing with so much demand on the remaining flows of the Truckee River.  During the last 3 years only a fraction of the total river flow actually reached Pyramid Lake.  (The first photo takes in a larger view of the Lake, but Anaho Island and the Pyramid are visible in both images.)

Recent scientific work reveals a dry future?

Oxbow Park on Truckee River

The USA Today reports in an article “Report: Climate change is here and getting worse” that we won’t have to wait to see the effects of a rapidly changing climate (mostly a rapidly warming climate).  Many  of us who were born in the 40s and 50s and 60s have observed this ourselves in the 14 years of the 21st century.  Young people, however, will never know the climate older westerners feel has already gone the way of the dodo.  Is it just the mis-remembrances of our own youth?

An article on global climate change in Science News (Cloudy Forecast, March 22, 2014) reports that “warming pushes [mid-latitude] storm tracks toward the poles”. Whether or not this movement of the storm track will result in a drier future for the Truckee River along with the entire desert southwest is yet to be determined.
