Toward Better Water Transfers in Coloradoand Cumulative Cost Avoidance John Wiener Presentation at USCID Conference on Urbanization of Irrigated Land and Water Transfers Phoenix, AZ, 28-31 May 2008 <John.Wiener@Colorado.Edu>; Extended Abstract and Hand-outs SLIDE SET MODIFIED FOR POSTING – References in Speaker’s Notes
Context: other talks in this conference • Commissioner Johnson: Climate change, institutional change, reducing rural losses • Jennifer Thorvaldson et al: new transfer forms and farmer interests • Jay Winner: the Super Ditch project… Organizing irrigators with different ditch companies, water rights, different diversions • MaryLou Smith will describe the process of working together in a situation structured by severe past adverse impacts and incentives pushing against cooperation
So, what’s my point? • Closer but not yet – needed transition to useful participation of the full range of interests affected by water transfers • Where market-based interest coordination fails, there will very likely be political assertions of interests, often without compensation to those affected. (Unless already a political process – e.g. IWRM). • Progress on “the elephant”, but risk that we hear the elephants’ question…
Conclusions • Better water transfers COULD BE DONE • Using 3 forms IN COMBINATION (handout) • PARTICIPATION of all interests is needed • COST COMPARISONS needed… • PARTNERSHIPS… • CUMULATIVE COSTS are NOT SMALL • Loss of agricultural capacity • Biological issues – almost unknown • Opportunity Costs – the loss of chance to make better use of land and water – The next frontier – Seeing a better future

South Platte North Platte Yampa/White/Green 10,300 AF Gap 107,800 AF Colorado 107,600 AF Identified Projects 404,300 AF Gunnison Dolores/ San Juan/ San Miguel Rio Grande Arkansas 2030 M&I Water Demands and Gaps (Colorado Statewide Water Supply Initiative slide -- except for comments) Beware! Self- reported “identified projects”! – --- If the big ones fail, the “gap” soars…
Ag water is still cheap! This is for the sale of water rights, not one use or a lease From Denver Water Integrated Resource Plan, and in Luecke et al., 2003, What the Current Drought Means for Colorado… (on-line from Trout Unlimited, Colorado)
$700 to $1400 “retail” prices not counting tap fees, etc… Even with ethanol… WATER WILL MOVE This is likely not correct - with inclining block rates, prices may be higher in most if not all cities.
12 to 23% of what’s left – or more ? ! BIG questions about this: water to acres varies, and the basis of the demand estimate is uncertain… And, no climate effects! SWSI slide
What’s a “Better” transfer?From whose point of view? • Better than “buy-and-dry”… traditional transfer: no future irrigation on that land • drop in value of production • drop in tax base • drop in labor • drop in inputs used and purchased • LESS RANDOM than traditional? Water right values not strongly linked to soil qualities, environmental values, spatial coherence with other values – important unknowns! (Briand et al. JAWRA 2008)
IF WITHIN MARKETS: New forms of water transfer wanted ( in handout – not just climate) • Short term spot market -- “water bank” • Long-term “rotating crop management” -- timing specified intermittent transfer to meet “base load” demand for municipalities (M&I sector), other high-value uses • Long-term interruptible supply arrangement -- transfer when condition is met, to meet foreseeable but timing-unspecified demand • [Along with temporary “bridge” deals (substitute water supply) and micro deals]
Markets in Colorado Are Not Working Well • Little information on who owns what, or prices paid. Compare real estate or almost anything else... • Lack and/or cost of information probably favors the few buyers over the many sellers • Asymmetry probably favors brokers even more! • Historic limitations on “beneficial” uses of water… • Biggest change: In-stream Flow Rights – recent innovation, unfinished project, many of these quite junior • Exclusion of those affected by “third party impacts” or externalities – limits on standing, timing of entry bad • Public interests not well identified or represented yet • Un-represented seek “entry” by political or regulatory means • Limits on kinds of contracts and arrangements – • short-term moves very limited • no long-term lease deals yet • “interruptible supply” very limited in Colorado • POOR MATCH of Costs and Benefits – physical, economic, temporal Inhibits INCENTIVES for better (Cf. IWRM!)
Long-Term Rotational Crop Management • Very long-term is ideal -- stability for all (cf Jay, and Jennifer Thorvaldson reports on preferences – not there yet… But…) • Planned locations of fallow/etc • Farm incomes and financing improved? • “Base-load” predictable water supplies • Only Up-front infrastructural costs (e.g., diversions, conveyance) – financed; no revegetation mess • “Pay-as-you-go” acquisition, not bonding, (save 50% at 3.25% interest for 30 years), better match of costs and benefits • ALL terms of deals negotiable - including end of term, indexing, risk management (Still some limits in new CRS 37-92-103 and -305(4)(a)(IV))
Long-Term Interruptible Supply • Also very long-term idea -- stability goals • NOT available in “3/10” years, 10 year limit deals in CRS 37-92-309 -- want much longer • Water moved on call, as specified, e.g. for... • Dry-year and drought recovery • Facility management • Wet-year opportunities (Aquifer Storage, etc) • Prices indexed to opportunity costs, costs of flexibility, and timing of “call” and situation • Pay-as-you-go instead of up-front and debt… • ALL terms should be negotiated!
Stacking for Management • Base-load from rotational fallowing • Intermittent needs from interruptible supply • Unforeseen needs from spot market • COMBINATION – (Cut to the chase: this is partnership, whatever you call it… Contracts are a means of risk distribution) • But, don’t these cost more? Don’t know… • Why should a city do this? (“Like, uh, what’s my motivation?”)
Missing Cost Information on “Buy and Dry” • revegetation required of formerly irrigated land… to what? “Native” may not be on the menu anymore…. • costs and duration of efforts required? • treated as proprietary, so far • successful cases? • standards may change – increased difficulty • soil erosion hazards increasing – higher intensity of precipitation • weed and fire loads questions – new obligations? • changed soils and new climate questions
What urban interests count? • Urban constituents are ratepayers BUTALSOtax-payers paying bonded debt • Supporters of open space, agricultural preservation, and rural areas • Voters for conservation etc – See Trust for Public Land “Conservation Vote” • Even in No Plan, No Foresight Colorado: 110 elections, $3.8 Billion • Recreators and Users of rural places • Members of a lot of groups… mixed bag! • Any one ask them? Not sure… polls…
What Urban Interests Count? • Simplicity, Reliability, “Invisibility”: Water System Management Values • Traditional is understood and predictable • New kinds of deals would require much more intensive collaboration – NOT SECRET! • Permanence (please see handout – principles page) • “We sell a tap forever” • Life of facilities and financing not a factor • Partnerships and long-term planning? Too new! • No incentive to match benefits and costs • Werner Von Braun
Cumulative Costs or Losses • Agricultural Capacity • loss of irrigated acreage • loss of soil qualities, especially if not farmed • loss of farm families and labor • loss of agricultural sector linkages/infrastructure • Biological Capacity • loss of connectivity of habitats and chance to preserve it • loss of diversity of habitats and chance to preserve • Loss of Future Choices – especially cheap ones…

Conversion of Best Farm Land – Near Loveland, in Weld County, CO I-25 BoydLake One square mile Slide by Tom Dickinson, IBS and Geography, Source: National Agriculture Imagery Program (NAIP),USDA-FSA Aerial Photography Field Office
What is now happening to the farm-dependent areas? SOME ethanol relief, but Long-term questions – feed prices… messy… Where the land is NOT CONVERTED to urban use? Population Growth is NOT evenly distributed
WEALTH and CAPACITY are not evenly distributed, either… d Effect of the ethanol boomlet? Hmmm… Source: USDA ERS (downloaded 17 May 08) http://www.ers.usda.gov/Data/PovertyRates/PovListpct.asp?ST=CO&view=Percent
Loss of Future Choices • Financial constraints on agricultural areas • Planning not a preference? Lack of capacity? • Fragmentation of land – • “Ranchettes” proliferating – very fast • Lack of ability to control development (Will?) • County coffers drained by costs>revenues • Amenities and rural quality of life – luxury or necessity for future development? • Prisons and nursing homes don’t care…
Newcomers and Exurban Development • The “ranchette” phenomenon -- currently 4 times the area occupied by all the cities and towns in Colorado -- but forecast to double in 30-40 years (Theobald et al.) … >35 acres unregulated… • Not new data… • Good neighbors? County and school services cost average of $1.65 for each $1 tax revenue • Coupal and Seidl, 2003 – CSU Dept Ag and Res Econ • Biologically, impacts may be disproportionate to area occupied -- (no planning allowed!) • Just hoping for easements to prevent problems? • THEY ARE NOT FARMING! (except for tax rate)

Cumulative Limits? • Water quality issues – • TMDLs? (total maximum daily loads) • Only very recently can Colorado Water Courts even consider water quality… Will there be a limit? How will transfers interact with NPDES? • Effects of erosion and changes in runoff from termination of irrigation? • HOW WILL A LIMIT WORK? WHO BEARS THE COSTS? • RACE TO BEAT THE LIMIT? Door slam? On whose future choices? Whose growth?
Inhomogeneity of salt loading sug-gests remediation by ending deep percolation in source areas -- Can we move irrigation someplace else? Figure from Gates et al., 2002, Monitoring and modeling flow and salt transport in a salinity-threatened valley. J. Irrig. And Drainage Eng., 128(2): 87-99; downloadable from journal site. Salinity above 1500 mg/l is bad for even stock watering; these levels also reduce crop yields. GROUNDS FOR FLEXIBILITY IN MOVING WATER FROM CURRENTLY IRRIGATED LANDS
Environmental Limits? • Endangered Species Act – What’s next? • lack of information on private land • Minimalist Minimum Stream Flow Vs Climate Change? (Trout Unlimited studies: Dry Legacy 1 and 2) • Wetlands-related limits? Invasives? • Changes to land and water already extensive • Re-Redistribution of water? • (Water Resources Impact May 2008) • No cumulative impact studies – stay blind? • Again, how will limits work? Whose cost? Incentive to race to avoid? Whose future?

Climate Change Vs Western Irrigation • USGCRP Sectoral Assessments (Water, Ag.): • Small changes with big water consequences? (2000) • Nationally, moderate effects on ag., no “crisis” (2001) • USGCRP: Central Great Plains (Ojima et al 2002) • With less water, irrigation hurt • With more water, irrigation loses to dryland • USGCRP: Great Basin/Rocky Mtns. (Wagner et al. 2003) • Ag declines in all scenarios • Recent Integrated Assessments (2004, 2005): • Current management in trouble • Ag. Loses water, all scenarios, even “best case” (references, interpretive memo available) -- changes in comparative advantage of irrigation versus dryland • IPCC Fourth Assessment, 2007 – various reports on website • US Climate Change Science Program, see CCSP website” <www.climatescience.gov>
Two Constants and the Low-Cost Social Welfare Function • Constant 1: Urban ability and will to pay -- for water AND ALSO for amenity, environment, open space, ag. preservation…. $24 billion locally voted in 5 years (US); $3.8B in Colorado so far, passing 110 of 148 measures (TPL) • Constant 2: Soil formation is very slow; climate is faster! • Suppose you owned all the pieces? What could you do to maximize the outcomes? • Answer tells what you want to maximize (pie flavor) • Answer tell how much you might get (pie size) • Problem: you don’t own it all. So, how to organize so as to get the biggest and best possible pie, for owners and others affected? • We use markets,mostly… Can they work better? • ECON 101 – CAN WE GET THERE?
MAKING MARKETS WORK • Markets need good information about prices and supply and demand… AND COSTS!!! • Markets can’t reflect unknown interests • Lack of vision – what value is possible? • Lack of planning and public interest, non-market interests, future interests, state interests? CUMULATIVE IMPACTS!!! Bite the bullet… • Internalize “externalities”! Third-party interests – Get them to the table! • Coordinate interests – make better deals! • Pay for interests! (Not necessarily money…)
