Water supply managers in Florida are increasingly turning to alternative sources in order to minimize the
environmental impact of groundwater withdrawals. Tampa Bay Water, the largest wholesale water supplier in
Southwest Florida, makes decisions regarding how to meet its customers" demands by
rotating and apportioning among existing sources (groundwater, surface water, the regional reservoir, and
desalination) to minimize cost and environmental impacts while maximizing reliability. As part of a study to
improve source allocation decision making by Tampa Bay Water an evaluation of Pacific and Atlantic Ocean sea
surface temperatures (SSTs) and monthly precipitation was performed to identify coupled modes of SST and
precipitation variability. The monthly patterns of precipitation were analyzed in relation to SST in the Atlantic and
Pacific Oceans using singular value decomposition analysis (SVD). Time-lagged analysis of SSTs and
precipitation were investigated in order to identify SST regions that show forecast potential for use in a suite of
hydrologic forecast models used by Tampa Bay Water.
