Throughout the year we conduct a variety of activities to accurately predict and plan for future water supplies, which include: • Forecasting plant water requirements based on anticipated electric generation • Accounting for the water we need and use • Monitoring snowpack reports • Studying stream flow forecasts, seasonal climate projections and changes to the Ogallala aquifer — the primary aquifer that underlies much of the region in Texas and New Mexico that we serve We have pursued an integrated water supply portfolio strategy, including owned or self-supplied water rights, reservoir storage, groundwater rights and a number of other supplies, such as municipal and recycled water supplies.
