This powerpoint presentation begins by providing background information on Tampa Bay Water that includes: historically groundwater supply-oriented;extensive water supply litigation in 1990'srelated to environmental degradation;agency reformed in 1998 as Tampa BayWater;permitting tied to reformation;groundwater reduction agreement; and,Master Water Plan developed foralternative water supply sources. The presentation outlines how historical events supported the need for improvedwater shortage planning, along with Water Shortage Mitigation Plan (WSMP) trigger criteria should be based onsupply reliability, and Enhanced Surface Water System (ESWS) supply reliability drives the need for a shortage plan. Water Shortage Mitigation Plan (WSMP)objectives include:can water shortage definitions be linked toconditions corresponding to high risk ofsurface water supply exhaustion; and,can mitigation activities (demandreduction, supply augmentation)quantifiably reduce risk of surface waterexhaustion? Objectives for WSMP Triggers include:Level 4 Water Supply Crisis - critical water supplyshortage, ESWS shutdown imminent;Level 3 Water Shortage - extreme water supplyshortage, reduced ESWS reliability with decreasingreservoir elevation;Level 2 Drought Warning - reduced rainfall andstream flow, reservoir storage adequate butdecreasing; and,Level 1 Drought Alert - reduced rainfall or streamflow, indicating potential for water supply shortage. Development of water shortage levels andtriggers, demand management actions, andsupply management actions are all presented.
