Long Range Water Supply Plan
Forney Dam at Lake Ray Hubbard
Dallas City Council September 17, 2014 Purpose
• To provide an update on the Current Water Supply Status
• To provide a progress update on the Long Range Water Supply Plan including – Updated water demand projections – Potential water management strategies
2 Outline • Current Water Supply Status and Drought Outlook • Long Range Water Supply Planning – Projected Demands – Current Supplies – Projected Needs – Management Strategies • Appendix
Lake Ray Roberts 3 Current Water Supply Status and Outlook
4 • June and August rainfall continued to improve drought conditions across Texas • Short term forecasts and enhanced probabilities for above-median precipitation through October, increase the potential for drought improvement or removal across far north Texas • National Weather Service (NWS) indicates a 65% chance of El Nino emerging in fall and early winter. Forecasters favor a weak event. – El Nino for Texas would mean a higher probability of rainfall in the winter and spring, although it is not guaranteed • The NWS Climate Prediction Center predicts normal temperatures and above normal precipitation through December 5 Current Drought Conditions Dallas’ Cumulative Precipitation
Through August, Dallas is 8.2 inches of rainfall behind for 2014
As of August 31, 2014 6 Current Lake Conditions
• Current hydrologic drought began 2010 – Lakes haven’t been full since May 2010 – 2011 worst one-year drought on record • Dallas’ water supplies are currently 30% depleted (8-Sep- 2014) – One month ago 27.2% depleted
– One year ago 27.7% depleted Lake Tawakoni 2013
7 8 Responses Stage 1 – Twice per week outdoor watering Stage 2 – Once per week outdoor watering Stage 3 – No Outdoor Watering (Except Foundations and Trees)
9 Long Range Water Supply Planning
Lewisville Lake and10 Dam Long Range Water Supply Planning
Dallas’ 1959 Long Range Water Supply Plan was updated in 1975, 1989, 2000 and 2005
– The 1959 study recommended that Dallas supply water to surrounding cities The passage of Senate Bill 1 of the 75th Legislative Session in 1997 changed water supply planning throughout the State
– Regional water planning groups established
– Regional and State water plans required every five years
– Local plans to be provided to the Regional Water Planning Group for consideration in the Regional Water Plan
11 Regional Water Planning
• State Water Plan due to Governor and Legislature in 2017 to meet the State Water Plan Schedule – Region C Water Plan is due to Texas Water Development Board (TWDB) in November 2015 – Council approved water management strategies due to Region C by January 2015
12 The Long Range Water Supply Plan (LRWSP) • Since the 2005 Update to the Long Range Water Supply Plan various 2005 planning assumptions have changed – The 2010 Census was released, water conservation plan success, the loss of Lake Fastrill reservoir site and Oklahoma water and the adoption of environmental flow standards by the State • Began work in Fall 2012 to update LRWSP – To develop population and water demand projections, evaluate existing supplies, and identify and recommend supply strategies to meet needs through 2070
13 Additional Studies in Support of LRWSP
• Sulphur River Basin Wide Study – Partnership with Sulphur River Basin Authority and four other regional partners – Identified combined water supply needs of partners – Recommendations considered in LRWSP multi level screening process • Upper Neches River Water Supply Project (Fastrill Replacement Project) – Run-of-River diversions from the Neches River near the Fastrill dam site with delivery to the Integrated Pipeline (IPL) pump station at Lake Palestine – Recommendations considered in LRWSP multi level screening process White Rock Pumphouse
14 Long Range Water Supply Plan Demand, Supply and Needs
15 Dallas’ Regional System Current Water Supply
16 Water Demand Projections
• Water Demand (gal/day) = Population1 x GPCD2
Million Gallons Per Day(MGD) = Water Demand X 365 1,000,000
1Population for Dallas and Customer Cities from TWDB, developed by State Demographer 2Gallons per Capita per Day (GPCD) for Dallas and Customer Cities from TWDB
• Population and GPCD coordinated with TWDB for consistency with regional planning • Previous conservation savings are considered demand reduction through reduced GPCD

20 Demands / Supplies / Needs
21 Future Water Needs Dallas’ Regional System
• Buffer Supply – Connected supply in Connected Supply surplus of current demands Buffer Supply and Shortages – Drought worse that the drought of record – Growth rate greater than projected – Emergency Demands
• Water Supply deficit (i.e. loss of reserve) begins in 2027
• By 2070 the DWU Regional System needs an additional 258 MGD

56 Water Conservation Accomplishments Conservation measures adopted by the Council in Oct 2001 have been positive 300
• Dallas saved an estimated 220 billion gallons of water since 2001 280 (extends supply by almost 1.5 years) • GPCD has been reduced 260 approximately 20% from FY01 to FY13 240 • As a result, Dallas has been able to mitigate the impact of drought
weather conditions on water supply 220 Dallas Water Use (GPCD) DallasWater • Since implementation of the Twice Weekly Watering Program in April 200 2012, water consumption is 5 to 6% lower despite similar temperatures 180
and less than half the rainfall

58 FY 2014-15 Water Conservation Strategic Plan
• Current 2010 Water Conservation Five- Year Strategic Plan due for update in 2015 • Tasks to evaluate proposed update – Analyze long-term demand reductions, water use and water loss data – Evaluate impacts of maximum twice weekly watering on water use demands – Assess savings, costs, staff time according to identified measures – Evaluate implementation strategies – Receive and incorporate stakeholder input – Modify prior recommendations and identify new measures – Develop draft Plan update
