Water Planning: Legislative Response to Drought
Late 1950s Drought of Record– 1957: Creation of TWDB– $200 million Water Development
Fund– 9 State Water Plans, 1961-2012
Late 1990s: Potential New Drought of Record– ~$6 billion economic losses in ‘96
(mostly agriculture)– ~300 entities with threat to water
supplies– 1997 & 2001: Implementation of SB
1 & 2 which created & refined regional water planning

Conservation
Focuses on efficiency of use/reduction of demands on existing supplies
Recommended 2010 strategies produce 767,000 acre-feet (municipal, irrigation; other)
Recommended 2060 strategies produce 2.2 million acre-feet (all types)
24
Reuse
Volume from reuse in2010: 100,600 acre-feet
Volume from reuse in 2060: 915,600 acre-feet
Nearly 350,000 acre feet of reuse projects implemented since 2007
