cautioned that estuarine conditions, which might result from restoring freshwater flows to the Bay to their historic levels could lead to increased turbidity from suspended sediment and loss of the "gin clear" bay remembered to have occurred in the 1960s and 1970s. Indeed, anecdotal evidence exists for generally turbid conditions in Florida Bay 100 years ago.

) would be redirected upstream into Shark River Slough and downstream to a very small degree into Craighead Basin and Taylor Slough, in an effort to replicate NSM flows (although CERP flow targets may differ from NSM estimates)

increases the uncertainty of such predictions. Shark River Slough In contrast to these minor proposed changes to flows in Craighead Basin and Taylor Slough, the CERP plans a dramatic increase in flow down Shark River Slough relative to the current condition (Figure 4~.

The upper estimates of saline groundwater flow would displace a one meter deep water column in ~ to 16 days, while the average residence time of water in the isolated basins of this region of the Bay is likely on the order of months (George Jackson, Texas A&M University and Ned Smith, Harbor Branch Oceanographic Institution, personal common., April 2002~. All of these estimates seem unreasonably high unless these fluxes are dominated by recirculation of Bay water through shallow aquifers under and adjacent to the bay.

Brand (2002) has developed this argument and summarized data indicating that phytoplankton blooms develop in the zone where relatively nitrogen-rich but phosphorus-poor water from the eastern Bay mixes with the phosphorus-rich but nitrogen-poor water flowing south along the inner southwest Florida shelf.

If the currents in 2050 are similar to present pattems, the central and we stem portions of Florida Bay would be exposed to increased nitrogen fluxes from Everglades restoration, even if water flows remain about the same in Taylor Slough and the eastern Bay. In conclusion, the ecological response to increased freshwater discharge to Florida Bay seems less certain than it once appeared.

The effects of such a fundamental water column shift on the seagrasses and associated resources of Florida Bay will be important to resource managers in the region, particularly because it is likely that these changes will be viewed by many as undesirable.
