This powerpoint presentation begins by providing a brief overview of drought issues. A 25 year simulation of a hypotheticalcommunity is presented and includes the following:moderate growth;mainly single family (SF) residential;no new water supply projects available; and,fairly standard, non-conserving demandpatterns. The model was used to test alternatives: model applied to a hypothetical system;25 year, monthly model;demands disaggregated - new/existing; by end uses- baseline, rationing and conservation; water supply including drought;reservoir operations; and,reliability criteria (rules). Drought recognition included:available storage = 12 kaf = 1 yr dems;reliance on spring snowmelt; and,failure to fill to at least 67% of capacity. Presentation conclusions indicate the following:planning can reduce risks of drought damage;important to understand the severity and extentof the design drought;conservation provides years of savings tosystem before it can be recognized;it can take 1 to 2 years for restrictions to makesignificant changes to demands; and,best course is to start conservation efforts early,and provide a drought reserve. Includes table, figures.
