Drafting of Projections
• Identify Cities & Utilities– Cities > 500 pop– Utilities > 280 acre‐feet
• County Projections– TxSDC half or full migration
• Project Cities & Utilities– Estimate utility pop– Based on county growth

The Take Away
• The State Water Plan projects:– Far into the future, and– Down to small cities and utilities
• Projections Are Developed With Regional input
• Goal is Credible Water Demand Projections and Meeting Water Needs
