About Dennis Ghiglieri

My concern for the Truckee River grew over the years. It started with picking up trash and supporting better water quality. I helped create the "living river"plan with other citizens on the Community Flood Coalition; a plan to reduce flood impacts to infrastructure through river restoration and protection of the floodplain. I understand how critical the Truckee River is to the environment – and economy – of our entire region. I'm hoping that through these pages we can all understand our connection to the Truckee River and why we need to protect it.

Gambling on Truckee Meadows water supply

Truckee River at the Plaza in downtown river in August 2014

On Sunday, September 28, 2014, the Reno Gazette-Journal published a headline story by Jeff DeLong: “Cusp of a Crisis” laying out the uncertain future for Reno-Sparks water supply.  Therein the Truckee Meadows Water Authority says it is relying on the “history” of the Truckee River to “pop us out of this drought cycle.”

But as we’ve written before, can we really rely on the past flows of the river to predict the future as each decade is warmer than the last?  Delong provides the stats demonstrating that the concern for water supply is real, but doesn’t write how the community will deal with it.  TMWA seems to be just spinning the roulette wheel.

  • Lake Tahoe at 1.2″ above its rim (Sept 30, 9 cubic feet per second (CFS) flows out)
  • Boca, Stampede, and Prosser Reservoirs at 19%, 25%, and 26% of capacity
  • TMWA’s drought storage reservoirs Donner and Independence at 66% and 91% of capacity (which in actual water is a little less than 22,000 acre-feet)
  • Customers reduced their use – TMWA claims by 10% saving 1,150 acre-feet – but leaves out if this is compared to last year or last month
  • The river at Farad is flowing at 100 CFS and 57 CFS through Reno (“normal” at Farad would be 5 times greater at 500 CFS).
  • TMWA serves 93,000 customers – 73,873 residential customers have water meters
  • Washoe County Water Resources Department and South Truckee Meadows General Improvement District will soon be merged into TMWA giving it 115,000 customers (basically, all the houses and businesses in the Reno-Sparks area)
  • 4,469 residential customers are still on a “flat rate”; they pay $100.63 per month regardless of how much water they use

Delong reported that Mike Carrigan, who serves on the TMWA board, favors requiring all TMWA customers be metered – especially important now that the drought has so reduced water supplies.  Water meters for all customers are long overdue. Delong wrote that the average flat rate customer (not metered) uses more than twice as much water as an average metered customer – 282,000 gallons compared to 124,000 gallons – per year presumably, although it isn’t stated in the article.

There are some big water users out there, too.  In 2013 one residence used 6.1 million gallons of water and another used 4 million gallons.  The 91st person on the list used nearly 900,000 gallons in 2013.  Should a single residence be using enough water to support 50 residential customers?  Should there be no limit for water use as long as the customer can afford it?

As interesting as reporting the top 100 water users is, the real issue is that the more water all of us use, the less water is available for the Truckee River which is the keystone of our community and the life-blood for fish and wildlife from Lake Tahoe to Pyramid Lake.

While meters are critically important to any water conservation program, without the proper rate structure and commitment by the water agency to set the rates to conserve water, customers have no reason to think about how much water they use. We discussed before that the current metered water rate structure does little to conserve water.

No one knows what the weather will bring this winter; and that’s just the point.  With our high per person water use, Reno-Sparks residents are victims of the gamblers mantra: “I’m feeling lucky.”

Is that a good way to run a community?

RGJ identified that some excessive water use comes from an unsuspected leak. Suspect a leak indoors or outdoors at your house is wasting water?  Call the Truckee Meadows Water Authority at 775-834-8005 to set up a water audit or if you’d like to try to find a suspected leak on your own go to TMWA’s website here.

Water for Tesla?  Not a problem?

When you think of an industrial facility such as the Tesla Lithium Battery Gigafactory, it is easy to overlook the need for water to run it.  But most places that make things need to use water at some point in the process.  The Tracy power plant east of Reno is an example.  It is located on the Truckee River because to make power you need water for both the steam-powered turbines and for cooling. How much water will the Tesla Lithium Battery Gigafactory require every year? Will Tesla’s gigafactory recycle water and have little net use of water?  Or will it require lots of water?

On September 5th, Mark Robison of the RGJ wrote an article “No water worries for Tesla at Reno industrial park.”  Therein he quotes the owner of the Tahoe-Reno Industrial Park (TRI), Lance Gilman, as claiming he has ample water.

“We’re really not impacted by the drought situation,” [Gilman] said. “Our water source appears to be incredibly stable and we haven’t seen a change in it at all (during the drought). We can pump 2 to 3 million gallons a day or more under today’s capacity and that’s, of course, expandable dramatically.”

In a more recent RGJ article on Reno’s potential lack of sewer capacity, it said TRI would like to receive water from the Truckee Meadows Water Reclamation Facility.

” The Tahoe Reno Industrial Center has already expressed interest in the effluent. The Regional Plan, however, prohibits the gray water from being shipped out of the service area.”

The TRI facility lies within the Truckee River watershed and groundwater or surface water use will impact the Truckee River and Pyramid Lake and communities east of the Truckee Meadows.

How much water Tesla needs and where that water will come from did not appear to be part of the decision-making process for Governor Sandoval’s negotiators.

It should have been.  The Tesla deal could cost us a lot more than the negotiated $1.25 billion.

“Where’s the water for Reno and Sparks?”

Carl Adams' YouTube Video "Where is the Water for Reno and Sparks"

In his public interest documentary video, Reno’s Carl Adams asks the $64 thousand dollar question about water.  Where is it?  Perhaps more of us should be asking this very question.  Watch this short YouTube video and you just might be.

I would add to Mr. Adams video another question or two.  How does continuous growth in residential and commercial water consumption affect our regions most iconic places such as the Truckee River and Lake Tahoe and Pyramid Lake?  Just where does “ground water” come from exactly?  Isn’t “ground water” in the Truckee Meadows recharged from the Truckee River and its tributaries?  And isn’t pumping “ground water” a way to “borrow” water from the next year in the hopes that it will be replenished during the winter months?  When do we let people know that more and more development – subdivisions and shopping malls with sprawling lawns and lush landscape more suitable for a rain forest than a desert – results in less water available for everyone?

Just asking.

Drought to persist through remainder of 2014

NOAA's National Climate Prediction Center shows the drought "persisting or intensifying over California and Nevada through the end of 2014.

Drought relief for Nevada and California is not in the cards according to the Climate Prediction Center at least through December.

“…the Pacific Northwest, and northern and central sections of California and Nevada, and much of western Utah are predicted to have elevated odds of below-median precipitation during the OND (October-November-December 2014) period…”

The description above seem mild considering the map that accompanies the explanation.  If the winter of 2014-15 turns out to be as dry as 2013-14, our lakes and rivers will be severely impacted again as human uses will take a larger share of the available water leaving little for instream flows.  Continued dropping of water levels at Pyramid Lake and Lake Tahoe and reservoirs is expected.

Will the Climate Prediction Center prognostication actually happen?  Or will the weak El Niño surprise us with something big as winter approaches.  It has happened before, but we are going to need more than one or even two excellent water years to make up for the losses we’ve seen in western Nevada over the past 14 years.

We in the west find ourselves in a long-term drought of 14 year duration and a warming climate.  Gambling that we’ll be bailed out of our excessive water use by a heavy snow year may not turn out to be a good strategy.

The Truckee River does not have enough water.  Ditches like the Highland ditch have effectively been dry now for more than 6 weeks.

The Truckee River does not have enough water to meet water rights in the Truckee Meadows. Area ditches like the Highland Ditch shown here have effectively been dry now for more than 6 weeks.  TMWA has had to release stored water from its reservoirs to supply its customers.
