Indiana’s Water Supply: Managing the resource, avoiding conflict - Sustainable Natural Resources Task Force 3/28/12

  1. 1. Indiana Wildlife FederationIndiana’s Water SupplyManaging the resource, avoiding conflictJACK WITTMAN, PHDNATIONAL DIRECTOR LAYNE GEOSCIENCESApril, 2012

  3. 3. Do we have a water problem? Is the past our future?  Climate change? Recent droughts – result of unplanned growth? Is Indiana vulnerable to shortages? Price/Value of water
  4. 4. Hydrologic Cycle – whatmatters
  5. 5. Hydrologic Cycle – whatmatters We have rules to protect quality
  6. 6. Important QuestionsDEMAND How much do we use/need? Where, when?SUPPLY How much water is available?
  7. 7. (More) Important QuestionsDoes our economy depend on water?Is water valuable?How much do we have?Where? When?
  8. 8. Indiana Water Budget  About 3 – 4 feet of precipitation / year  1 foot of water in all the streams  About ½ to ¼ ft recharge to groundwater (where there are aquifers)
  9. 9. How much water do wehave?Depends on locationSurface waterGroundwater
  10. 10. Hydro-Geography of Indiana Surface water  Ground water (shallow)
  11. 11. Hydro-Geography of Indiana  Surface water  Ground water (shallow)Great LakesAnnex 2001
  12. 12. Groundwater availability
  13. 13. Where do we need water?Where we have demandWhere infrastructure existsWhere there will be growth
  14. 14. Where do we use water?  Cities  Power Plants  Industrial facilities  Irrigation
  15. 15. Transportation Infrastructure
  16. 16. Growth (green)
  17. 17. Do We Know the Risk?
  18. 18. Large demand,marginal suppliesGrowing demand,vulnerablesupplies
  19. 19. What are the challenges?Interbasin transferAquifer storageEcosystem flowsJurisdictions
  20. 20. Water Supply Planning Planning is the norm  TX, KY, VA, PA, MI Management of resource  Growth  Regional demand Collective self-interest
  21. 21. Risk of Regional Shortages Barely adequate local supplies in Central Indiana Limited groundwater in Southern Indiana Growth and infrastructure investment in the South Regional planning the norm (MI, IL, KY) New law on groundwater may be made in court
  22. 22. Water Policy and Law Indiana’s water “grid” is a patchwork of local systems.  Local concerns  Limited resources  No investment  Difficult to integrate  1+1+1 = 1 Regional systems  Reliable  Resilient  Diversified
  23. 23. Water Policy and Law Evolution of regional systems  Rethink the water grid  Physical infrastructure  Institutional infrastructure  Economic incentives
  24. 24. Water Policy and Law Rethinking local control  IURC needs to revisit water pricing policy  Need incentives for wholesale water providers  Regional systems can manage supply, local utilities can manage demand and deliver
  25. 25. Drought Proofing Ohio River is a sustainable supply in the South Bank filtration could be the best of surface water and groundwater Drought-proof supplies in aquifers along the River
  26. 26. AnswersDoes our economy depend on water? YESIs water valuable? YESHow much do we have? GW: 100 M acre feet Price $300 - $3000/AF  $30 - $300 B
  27. 27. What needs to happen?Modernize regulatory infrastructureDevelop statutory guidance Survey resource Map needs Consider options Make investment priorities
  28. 28. We decide our future
