The Santa Clara Valley Water District (SCVWD), as well as other California water
suppliers, are facing the crucial question of whether there will be enough water
to satisfy future demand. To address potential water supply shortfall and to
ensure a reliable supply of high quality water through the year 2020, the SCVWD
formulated the Integrated Water Resources Plan (IWRP) in March 1996. The IWRP's
preferred strategy includes four components: water banking; non-potable
recycling; demand management; and long-term water transfers. To gain a better
understanding of how the IWRP strategy will perform under future hydrological
events, SCVWD staff performed a statistical analysis of the likelihood of water
shortages for three different demand levels. In order to estimate how often a
shortage event may occur under the simulation model used in the IWRP analysis,
the 75 years of historic hydrologic data used in the IWRP model was expanded to
100,000 years by random selection. The data sequences selected included drier and
wetter periods than have historically occurred. The statistical results for
predicted water supply shortages over this time period are presented in this
report. Includes tables, figures, appendices.
