The purpose of this report is to (1) compare the extent and duration of the flooded area in isolated wetlands located in three regional well fields operated by Tampa Bay Water in the northern Tampa Bay region during a period before and a period after reductions in the rate of groundwater withdrawals; (2) evaluate the ability of the flooded area duration integrated over the two periods to provide evidence of the change in wetland hydrologic conditions; and (3) discuss the potential use of wetland flooded-area data to interpret long-term wetland vegetation monitoring data.
