  4. 4. Presentation Outline − Regional water planning overview − 2016 Region K Water Plan overview − 2016 Plan focus on Water Conservation
  5. 5. Regional Water Planning Overview About the Planning Groups… − Volunteers with various levels of experience in the water industry − Diverse backgrounds: − Public − Counties − Municipalities − Industries − Agriculture − Environment − Small Business − Power Generation − River Authorities − Water Districts − Water Utilities − Groundwater Management Area
  6. 6. 2016 REGION K WATER PLAN OVERVIEW
  7. 7. Region K Population Projections
  8. 8. Available Water Existing Supplies
  9. 9. Available Surface Water and Groundwater − Total available water approximately 1.3 million acre-feet − 1 acre-foot = 325,851 gallons − Over 900,000 acre-feet is surface water − Surface water availability modeling used to determine decadal amounts − New “critical” year of 2011 for run-of-river water rights − Region K major water supply sources include: Highland Lakes, Colorado River, other local surface water sources, numerous major and minor groundwater aquifers
  10. 10. Major Aquifers in Region K
  11. 11. Minor Aquifers in Region K
  12. 12. Groundwater Conservation Districts − The majority of aquifers are managed by Groundwater Conservation Districts (GCDs). − Region K has a GCD in every county except Llano and Williamson.
  13. 13. Region K Water Needs by Category of Use for 2040 and 2070 Shortage (Need) = Existing Supply – Projected Demand
  14. 14. Water Management Strategies How to meet Region K water needs? − Drought Management − Conservation − Water Reuse and Reuse-sourced projects − Development of Groundwater − Includes Fresh, Brackish, and Saline − Aquifer Storage and Recovery (ASR) − Irrigation On-Farm Conservation and Delivery Improvements − New Off-Channel Reservoir Storage

  17. 17. Role of Conservation in 2016 Region K Water Plan − Conservation strategies included in Plan:  Wholesale Water Provider Conservation (LCRA, Austin)  Irrigation / Agricultural Conservation  Municipal Conservation − Wholesale Water Provider Conservation (LCRA, Austin) − Measures include:  financial incentives to assist customers with conservation implementation;  education effort assistance including irrigation evaluation training and community outreach;

Role of Conservation in 2016 Region K Water Plan − Irrigation / Agricultural Conservation − Focus in Colorado, Matagorda, and Wharton counties − Measures include:  On-Farm (land leveling, levees, and field inlets);  Conveyance Improvements (canal lining, SCADA controls, etc.); and  Sprinkler Irrigation (conversion from flood to sprinkler) 2020 2030 2040 2050 2060 2070 On-Farm Conservation 20,000 26,000 32,000 38,000 44,000 50,000 Conveyance Improvements 5,200 17,000 29,000 41,000 53,000 64,300 Sprinkler Irrigation 1,430 7,150 14,300 17,875 17,875 17,875 Water Savings (Acre-Feet/Year)Irrigation Conservation Strategy
  19. 19. Role of Conservation in 2016 Region K Water Plan − Municipal Conservation − Municipal demand projections in Plan incorporate assumed future water efficiency savings due to federal standards for plumbing fixtures and appliances − Water management strategy recommendations for Municipal Conservation go beyond the above assumption − Only recommended for municipal Water User Groups (WUG) having a 2020 projected Gallons per Capita per Day (GPCD) of 140 or higher 2020 2030 2040 2050 2060 2070 Municipal Conservation (including Austin) 31,253 41,132 51,844 62,202 73,092 86,222 Water Savings (Acre-Feet/Year)
  20. 20. Role of Conservation in 2016 Region K Water Plan − Municipal Conservation − 51 municipal WUGs have conservation as a strategy − Measures include, but are not limited to:  Water loss audits; leak detection and repair  Smart meters and automatic meter infrastructure  Landscape irrigation evaluation, standards, and schedules  Public outreach and education programs  Reuse  Aquifer Storage and Recovery - ASR
