Who Should Get the Water, when push comes to shove?



I wonder if they'll take 213 pounds of  whelks for an acre-foot. of water.
This post series encourages stakeholders, by becoming as knowledgeable as possible in a very short time, to vigorously participate in the design of their water futures, which are destined to become closely monitored,  metered, and regulated by agencies both appointed and elected. Need to know includes such basic as how water is measured (acre-feet as well as gallons), how geography is delineated for water accounting, what aquifers or water-basins are, what are the sources of all water supplied to Californians, who determines allocations and use, and more.

Long-term design is most likely to successfully meet all stakeholders' goals when based on science, inclusive demographics, as well as accounting for and balancing the needs and desires of specific interest groups like agribusiness, environmentalists and planners. 

We focus on the Central Coast of California. The conflicts of interests with the greatest impact on individual water futures in Santa Barbara County is that of sustainable water use and the California agricultural lobby, with groundwater issues pivotal. The new water regulatory environment outlined by Governor Brown, with conservation measures ordered for urban users of a 25% mandatory cut in water use, still excludes specific regulations for agriculture, though agriculture accounts for 80 % of water use in California. The Central Coast, though climatically more desert than tropic, is considered the breadbasket of the world, but is not a natural world wonder but an intensely engineered one.

The legislation passed in September of 2014 specifies that local agencies need to develop plans for groundwater use  that can be tailored to regional needs and conditions.:
The legislation prioritizes groundwater basins that are currently overdrafted  or at risk and sets a timeline for implementation:

- By 2017, local groundwater management agencies must be identified;
- By 2020, overdrafted groundwater basins must have sustainability plans;
- By 2022, other high and medium priority basins not currently in overdraft must have sustainability plans; and
- By 2040, all high and medium priority groundwater basins must achieve sustainability.
No immediate conservation measures were mandated for agriculture. Simultaneously, throughout the Central Valley, more wells are being dug deeper and at greater cost by those who can afford it to meet dwindling  supplies of water for their purposes. Similar pictures reflect water scarcity drilling frenzy and groundwater depletion in Northern India, Syria, Saudi Arabia and the US. This is a water arms race, where he and she who can drill deeper survive longer while  land is reported to be sinking half an inch a month and groundwater levels appear to be sinking faster in the Central Valley than anywhere else in the United States, according to a recent U.S. Geological Survey.



Consider the  example of the City and County of Santa Barbara, iconic of the good life

The City of Santa Barbara, to use one specific  example used for the purpose of limiting the complexity of the water supply and demand issues to one relatively simplified ,localized example for possible better understanding of how water supply and demand work in most regions of California, depends on five different water supplies to meet local demands: Local Surface Water, Local Groundwater, State Water, Recycled Water, and Desalinated Water. Each of these will be addressed below to evaluate how they might or might not meet SB community demands for clean water.

 Under normal weather conditions average water use by Californians  is supplied 70% from surface water supplies (rivers, lakes, stored water such as reservoirs and canals) and 30% from groundwater supplies, stored in natural geological structures called aquifers. During extended drought the average user draws on groundwater supplies for 80% of water used. In some regions, such as the Central Coast, almost 100 % of the water supplied is from groundwater.
Groundwater basins are prioritized under the new sustainable water legislation according to level of concern for risks of depletion, subsidence, and saltwater-intrusion.

Prioritization studies suggest that several regions are at risk for supply exceeding demand: specifically the Cuyama and San Antonio regions.


Most estimates of future supply of water are based on data that is sketchy, such as that for groundwater reserves, assumptions about use, which may be accurate or may not, and weather predictions, which under the condition of Climate Change uncertainty, makes predictions regarding future supplies porblematic.The above line graph predicts that for three out of the five detailed water accounting units (DAUs, see below),  supply may be just barely met in 2040.

Fundamentals

When speaking of large water quantities, the unit of measure is the acre-foot or acre-inch, the amount of water required to cover one acre either 12 inches or 1 inch. Most Americans are familiar with gallons, so to get an idea of the large quantities used to supply water to a region or for irrigation, stakeholders who want to speak the water world language, need to become comfortable with both. One-acre-foot is 325,851 gallons; an acre-inch is 27,154 gallons.

Putting Stats into a Context

The average household in this County uses between 30,000 to 90,000 gallons of water a year. According to Wikipedia,
 "A 2000 study of a sampling of 735 California homes across ten water districts found that the weighted average annual total water use of these homes was 132,000 US gallons (0.41 acreft) per year or 362 US gallons (0.00111 acreft) per household per day."


The average per capita use of water in the city of Santa Barbara is 130 gallons per day, which reflects current conservation practices, with Goleta using less and Montecito about triple SB City residential use. These data are supplied as basics for water literacy in our region. On the average, at least half of local domestic water use is for outside purposes, including but not restricted to landscaping, which is particularly important in Montecito.  About half of the water used indoors is for bath-shower and toilet. 

  Supply-side



 The County contains four principal watersheds: the Santa Maria, which includes the Cuyama and Sisquoc watersheds and covers 1,845 square miles; San Antonio Creek that covers 165 square miles; Santa Ynez that covers 900 square miles; and the South Coast, which is comprised of 50 short, steep watersheds extending from the ridge of the Santa Ynez Mountains to the Pacific Ocean.  Four major rivers drain these watersheds: the Santa Maria, Sisquoc, Cuyama, and Santa Ynez. Rainfall is variable, with stream flow a function of rainfall. Accounting units are not geographically the same as watersheds, see below for accounting. Most avocados and 75% of nursery and hot-house crops and plants are raised in the South Coast watershed area, with water supplied from groundwater and surface water supplies including Cachuma, Gibraltar, and Juncal Dams (under normal conditions, which exclude the present extended drought). Wineries are scattered throughout the county. (blue on map below)



 Under normal weather conditions average water use by Californians  is supplied 70% from surface water supplies (rivers, lakes, stored water such as reservoirs or Lakes such as Lake Cachuma or Gibraltar Reservoir, along with whatever is present in canals) and 30% from groundwater supplies, stored in natural geological structures called aquifers. During extended drought the average user draws on groundwater supplies for 80% of water used. In some regions, such as the Central Coast, almost 100 % of the water supplied is from groundwater. The state allocates but does not always supply what is classified as surface water.

 Consider the Other Suppliers



Surface Water: Lake Cachuma is SB’s primary source of surface water, though recharge is from rain and other sources. As of Aug 25, 2015, 40,751 acre feet are stored, according to the Bureau of Reclamation, which is 21.1 % of capacity storage. On an average annual basis, Lake Cachuma provides approximately one-quarter of the water used in the Central Coastal Region and 80 percent of Santa Barbara County’s   water supply.

State Water: For 2015 SB Co requested 45 486 acre-feet from the State Water project and was granted   6823 AFY, or 15% of the water requested. The ultimate source of all water for the State Water Project is the Feather River,a tributary of the Sacramento River. State water's largest reservoir is Lake Oroville, with a water capacity of 3.5 million acre feet. This August 2015, Lake Oroville is at 25% capcity, or about 890,000 acre feet. Santa Barbara County is entitled to 45,486 AFY., stored in the San Luis Reservoir. more at: http://www.pacbiztimes.com/2014/02/07/tri-county-cities-scramble-as-state-cuts-water-deliveries/#sthash.k3qG3sjC.dpuf


Under conditions of extended drought state-wide, such as we are now addressing, State Water supplies tend to dwindle to almost nothing,

Recycled Water: The City's Recycled Water Project recycles approximately 800 acre feet of treated wastewater each year.The cost per acre foot of recycled water is approximately $1,200. To put this figure into perspective: Central valley water costs farmers anywhere from $500 per acre-foot up.



Desalinated Seawater : Santa Barbara's desal plant was constructed in 1991 and deactivated after plentiful rainfall made operation un-economical. The capital costs to reactivate the plant with a capacity of 3,125 acre-feet per year1 (AFY) are estimated at $55 million. Annual operating costs are estimated to be about $4.1 million at full production (for 3,125 AFY of water supply), and about $1.6 million in standby ready-state mode. Planned delivery of desalinated water is for 2016.

None of the above will meet the demands of residents in SB County.

The Biggest Source and Issues  for Groundwater


During extended drought conditions such as we are dealing with today, August 30, 2015, ground water is the only source on which water users in the Central Coast can rely.

Groundwater: Although there are many, to a large extend unclassified and unmonitored groundwater basins or aquifers on the central Coast, the major ones are increasinglu understood and monitored. The major South Coast Groundwater Basins include: Carpinteria, Montecito, Santa Barbara, Foothill, and the Goleta Groundwater Basins.  The major groundwater basins within the Santa Ynez River Watershed are, from east to west: Santa Ynez Uplands, Santa Ynez River Alluvial, Buellton Uplands, Lompoc Uplands, Lompoc Plain, and Lompoc Terrace Basins. These basins are adjacent to the Santa Ynez River and lie between the San Rafael Mountains to the North and east and the Santa Ynez Mountains to the South. Each basin is affected to some extent by water rights agreements and Cachuma Reservoir operations. Primary among these is the Water Rights Order 89-18 and the 2000 Biologic Opinion from the National Marine Fisheries Service. 

Water use within the Santa Ynez Uplands Groundwater Basin is primarily for agriculture though there is also urban use within portions of the basin supplied by Santa Ynez Water Conservation District ID#1. The most recent report, dated 2014, by SB county agencies indicates how water levels in all major basins have changed according to agency calculations. http://cosb.countyofsb.org/uploadedFiles/pwd/Water/WaterAgency/Status%20Report%20on%20Groundwater%20Basins_Final2.pdf




Geographical Accounting Units 

The DAU is the geographical accounting unit for water in a specific area. This concept is useful largely  for regulatory and insights, based on diverse studies, with diverse purposes.  the stakeholder needs to attend to who reports what and why.



To summarize the last three posts, if stakeholders want their water futures to match their needs and desires for how water is accessed and distributed, they need to become knowledgeable and vitally active.

Getting a Grasp on Our Water Future

The next three posts present an overview of what stakeholders in Santa Barbara County need to know to homestead and steward the new regulatory water environment.

 
Applied improvisational intelligence: bike wheel for spinning drive wheel


Humans are resourceful, from the most trivial quick fix/substitution-work-around-make-do bricolage to history-changing creativity and art. Trivial challenges tend to be met by working improvisationally with whatever is at hand; we all do it.

Traveling in Asia and Africa during the sixties and seventies, I used Rémy Martin cognac (40 % alcohol) to brush my teeth to minimize threats of water bacteria I had not adapted to. This was an effective workaround for at least 20 years: one very palatable “clean” liquid substituted in a necessary and usual practice for the usual liquid (tap water of US-standard cleanliness) with relatively little cost or effort (Remy Martin was easily accessed at tax-free airport gift shops at small cost). This particular work-around no longer works, for several reasons.

Remy Martin has become costly over the period of 1963 to 2015  and is no longer a viable substitute for washing and cleaning.  Ultimately, Remy Martin depends on the default of water for growing grapes in a process that double-distills white wine produced from grapes grown in Cognac, France, requiring a rough average of 720 liters to one liter of cognac (using the Water Network statistics for wine's water footprint). What will Remy Martin do when water becomes too costly to create cognac?  Water, the universal default for all liquids,  is also becoming costly and clean water has become scarce.What will we do when neither Remy Martin nor water is a viable alternative for keeping our teeth clean?

2015 Water  Crisis


In 2015 we face a problem no species has ever effectively addressed in recorded history: clean easily accessed water is becoming scarce worldwide. Providing food, drink, and sanitation to over 7 billion people has unbalanced the “water supply equals water demand” equation.   Consider: wine cannot be substituted for water when water becomes scarce and costly. Listerine cannot be substituted for water because it is mostly water and alcohol, which is also water-based.



 Wine’s water footprint, as referenced in the last post in this series, as calculated by the gold standard the Water Footprint Network (based in the Netherlands) and broadly publicized by Latin America’s largest wine exporter Concha y Toro averages720 liters of water per 750 ml bottle of wine.  Concha Y Toro, with a smaller footprint, is a wine company committed to water stewardship, so most vineyards are drip irrigated, but under extended drought the water sources for drip irrigation could become depleted.

The other top grossing agricultural products for California  and their water footprints are as follows:
milk: 1000 liters;
1grape:  .3 gallons, 
1 almond: 1.1 gallons;
1 head  lettuce:  3.5 gallons 
1 strawberry:  .4 gallons
Santa Barbara per capita water use per day: 124 gallons
Montecito average per capita water use : 311 gallons

 

Water footprints represent the water required throughout the life cycle of a product or person in a specific place and time.  The tools used for calculation reflect the frameworks and concepts of those who designed the calculators and methodologies, so the products evaluated by one system should be used with caution when comparing with outcomes from a different system. Water use, which corresponds more closely to what would be metered on a water bill or well, is different from water footprint and should not be compared; the latter considers evapotranspiration, soil moisture, rain,  as well as how much water is required to bring waste water associated with the whole life cycle of the wine process up to ambient standards.

The drought has heightened interest in dry-farming as a solution to water scarcity, but this would have an insignificant effect on overall water use. Dry farming crops still requires water, both as rain (usually at least 12 inches) and groundwater, which is frequently found at considerable depth, sometimes more than 100 feet, which would mean roots of any  When groundwater itself is a resource already being overdrafted, tapping into this threatened source of water is not necessarily the solution. Central Valley and some Central Coast farmers have responded to falling groundwater levels by digging down deeper.

Research at UC Davis on grapes dry-farmed and grapes farmed with rain and irrigation in the Carneros Region indicated that the dry-farmed vines yielded 4.9 tons per acre and required 14.2 gallons of soil-sourced water to produce a 4-oz glass of wine (5 glasses to a 750ml bottle) , while the irrigated vines, yielded 6.3 tons per acre and required 15.3 gallons for a 4-oz glass of wine, using about half from rain and soil and half from irrigation.

 California, the Central Coast Region, and Santa Barbara County


The ration of water to wine, from a water shortage perspective, is not sustainable, regardless of wine's influential position as second leading revenue-generating commodity in California. The fact that the water-footprints of the other top ranking commodities, i.e.,  almond, milk, strawberries, lettuce, and avocados, are larger than wine's doesn't change the unsustainability of all of these products, although each industry is bound to have powerful lobbies to influence in their favor  the brand-new water-regulatory environment. Some farmers have already adapted by moving grazing lands out of the County, cutting down trees--especially avocados,  or letting fields go fallow. Most strategize action for long-term survival. Their plays are already in place; for the average stakeholder to join the game, knowledge, skills, and a strategy need to be acquired.

The wine industry is the focus of this post series not for attributing blame but for a solution-oriented reason. Wine and particularly premium wineries have defacto leadership positions in many communities and are good candidates for leadership in the water stewardship niche. California ultrapremium winery owners and winemakers tend to be masterful mavericks with most of the skills, knowledge, and ethics to bricolage a water stewardship niche,occupy it, and develop it.

More than 1,200 wineries in the state, ranging from small boutique, family-style wineries to large corporations like E & J Gallo Winery, together harvest about 4 million tons of grapes per year. An estimated 90 % of California vineyards are irrigated, Using averaging statistics for winegrowing and inferring  production of grapes into wine, about 756 bottles of wine are produced from a ton of grapes. Doing the math,  756 bottles of wine per ton of grapes requires 720 liters of water x 756 bottles per ton, or 544,320 liters of water are required per ton of wine-grapes eventually embodied in wine. Four million tons of wine-grapes harvested and bottled indicate a final embodiment of 4 million x 544,320, or 2,17, 280 liters of water.  Data from 2012 indicate that 58,000 active vineyard acres support about 280 wineries in the Southern Planning Area (12 Southernmost counties including Tribal Territories).

Given that almost all of California is experiencing historic drought and depleted supplies, where will this water come from?


The water cycle suggests that water is eternal, but fails to indicate that clean water is not. As water cycles through the air and ground it picks up dirt, radiation, and chemicals that cannot be readily cleaned within or without this cycle.

Getting More Resourceful: the Stewardship Niche as Bricolage 


At first blush, no good substitute comes to mind for clean water. Nor second or third. While bricoleurs--in the US referred to as do-it-yourselfers-- are good at work-arounds, working around requires working on the project.

The Project


An identified but scantily occupied niche is that of global steward. The rest of this post and the next few are devoted to how stakeholders can occupy this niche, starting with water stewardship. On the water planet there is likely no substitute for water but there are alternative ways to participate in this cycle.

Bricoleurs, as indicated in the top image, use whatever is at hand or in the environment to get done whatever project or problem is tackled. As new problems and challenges arise, the original project transitions to a brand-new project, making whatever is at hand an environment with unexplored resources. 

The  bricolage project considered here is the creation of a water stewardship niche. Bricoleurs by definition creatively manipulate objects to suit the task at hand. Given the crisis, creativity is a survival requirement for the next 25 years, at the least.
 
Stakeholders who hope to  successfully occupy the 2015 stewardship niche, not unlike those who wish to become US citizens, need to meet key requirements. Stewards should be able to navigate unexplored territories, implying improvisation;  paying attention, they will gain knowledge of each habitat: who dwells there, who are the alpha player and predators; what are the issues of major concern; what are the subtexts;  how do things work in this niche--the good guys and the bad guys (predators)--who stands to gain and who to lose according to which policies and practices, who has the power to get things done, how and why and what;  strategies likely to achieve goals of each player; the system outcomes and inputs. Niche occupation in 2015 requires cognitive and improvisational skill as well as information that evolves. Robinson Crusoe, for example, could be considered a master bricoleur, whose goal was survival; not only did he make do with whatever was at hand, he thrived on his own ingenuity and resourcefulness.

Bricoleurs as mentioned above solve problems by thinking creatively about whatever is at hand, which in the new groundwater regulatory environment implies that a rule is only a provisional guide, and legacies  and grandfather clauses need to be continuously re-evaluated. The next post considers approaches to this environment.


Historically, people solved water shortages in a variety of ways, including substitution, conservation, reduction or by moving i.e.finding a new habitat with little or no competition and ample resources or by
identifying and/or creating an unoccupied niche and inhabit it.


In the case of Homo sapiens, the last one seems like the best option, from the perspective of most likely to succeed.

  To Bricolage Our Central Coast Water Futures, Assume Very Little

The Big Picture: we depend on rain falling somewhere and transport systems to deliver water from water-rich areas to water-poor ones. When the water-rich regions dry up, we are at a loss for fresh sources. In Central California 1.53 million people depend for 83% of their water supply on groundwater. Groundwater is considered worldwide as the water resource of last resort. Transport resources such as the State Water Project and Central Valley Project are under major stress. Local water resources are also overdrafting groundwater, but in many areas such as the Central Valley, the waiting lists to dig new wells to tap into groundwater are a year long.  It could be up to us to create a viable work-around.

The Penultimate Last Resort


While most precious natural resources such as the air we breathe have become regulated by governmental and non-governmental agencies, groundwater in California is unregulated. The result is what is known as a tragedy of the commons: to guard against the possibility that neighbors might take more than their share of what is regarded as a common  free resource, each individual takes a little more than their fare share, since no one is paying close attention to what is even a fair share. so when groundwater supplies are threatened by overpumping, it takes a major crisis for anyone to do anything to mitigate the threat of water scarcity. Groundwater in the Central Valley is overexploited, land is collapsing from overpumping, wells must be dug deeper and depper at higher and higher expense, and yet

Tulare farmers and homeowners drilled 796 new wells in the first nine months of 2014. Two-thirds of the wells permitted were granted to farmers for crop irrigation.
Fresno County has some of the highest drilling activity in the region, with a steady uptick in agricultural and private domestic wells drilled since 2011. Agricultural wells in 2014 have already surpassed the number drilled last year, and is more than three times the number drilled in 2011.  
The Central Valley aquifer is California's largest aquifer, recharging slowly for the past 20,000 years. Most of the more than 100,000 wells that pierce the valley floor are unmetered and landowners have taken what they wanted for irrigation for at least 100 years.  According to the LATimes, "Scientists estimate that since the first wells were drilled by settlers more than a century ago, pumping has depleted Central Valley groundwater reserves by 125 million acre-feet."
"The Paso Robles groundwater subbasin supplies water for 29 percent of the population and an estimated 40 percent of the agricultural production of San Luis Obispo County. Groundwater levels in the basin have been dropping rapidly in recent years, with many areas experiencing groundwater level declines of more than 70 feet. As a result, many wells have gone dry and groundwater users have been forced to deepen their wells or drill new wells.  " California Water Foundation
"Central Coast groundwater supplies are seriously threatened by over-pumping that causes seawater intrusion, a challenge unique to coastal communities. Seawater intrusion results in saline groundwater that is unsuitable for irrigation or domestic use, directly threatening the Central Coast’s economy, where many high-value, salt-sensitive crops, such as strawberries, are grown."  California Water Foundation
 In some systems, when large amounts of water are pumped, the subsoil compacts, thus reducing in size and number the open pore spaces in the soil the previously held water. This can result in a permanent reduction in the total storage capacity of the aquifer system. Land subsidence occurs when large amounts of groundwater have been withdrawn from certain types of rocks, such as fine-grained sediments. The water is partly responsible for holding the ground up, so when withdrawn, the rocks falls in on itself.Groundwater levels have been dropping rapidly in the Paso Robles subbasin in recent years. Four areas of subsidence have been noted in the Paso Robles region.
Seawater intrusion began in the Salinas Valley by the 1930s. Since that time, seawater intrusion has continued and now extends more than five miles inland....Seawater intrusion was first documented in the Pajaro Valley basin in 1953, and has continued since that time. Because the Pajaro Valley basin is in severe overdraft, groundwater levels have dropped below sea-level, allowing seawater to move into the aquifer. Seawater intrusion in the Pajaro Valley basin has been observed up to three miles inland. Groundwater trends in the Santa Barbara South Coast vary by groundwater basin. In the 1970s groundwater levels in the Santa BarbaraBasin dropped as much as 100 feet, which led to some sea water intrusion. The Goleta basin has been in a historic state of overdraft, after which the  Wright Judgment in 1989 adjudicated the water resources of the basin in court. Since that time, groundwater levels recovered.(as reported in 2014)

Need to Know

 Drought is providing an opportunity to re-think how we use water, where regulation is required for better management, and who should be the managers. These posts support stakeholders who wish to assume responsibility for their homes and environments. Over the next 10 years the free unmanaged groundwater basins characterizing California water use for the last few thousand years will become highly regulated--to suit those who are invested in the outcomes and participate in the design and implementation processes. Stakeholders who would like to have some control over their water supply need to educate themselves and become participants in this process. Key concepts to be understood  well enough to manipulate creatively as tools for influencing the new regulatory environment include:


average household water use 
A 2000 study of a sampling of 735 California homes across ten water districts found that the weighted average annual total water use of these homes was 132,000 US gallons (0.41 acre·ft) per year or 362 US gallons (0.00111 acre·ft) per household per day

Water Basics

 

 

Water resides in three places on earth, categorized as: surface water on the surface in lakes, streams, reservoirs, ice, snow, and permafrost; atmospheric , and under ground, categorized as soil moisture and groundwater. Normally, water users get their water from the sky, via from wells, reservoirs, and city, state or federal water-supply systems. Under extended drought conditions, surface waters dry up, dams and reservoirs become depleted, wells can no longer draw from groundwater with water table levels dropped too far, and people worldwide tap into deep, non-renewable ground-water stores. Partly because this resource is out of sight, it has been largely unregulated worldwide. Because it has been unregulated and unmanaged, it has been exploited.

The Texas Supreme Court concluded  in 1904 that groundwater was too “secret, occult, and concealed” to ever regulate


Supply and Demand on the Central Coast


The Santa Barbara County/Central Coast Region is conceptual. That means it can be reconceptualized as we go. The landscape is categorized as Mediterranean, largely arid, with less than 20 inches of rain in a few months only. Most likely, under conditions of unpredictable Climate Change, this too will be reconceptualized. The next post approaches key water concepts as an improvisational landscape with water facts  such as  surface water supply, hydrologic units, annual rainfall, groundwater regulations, all  treated as evolvable tools for the project at hand.
