Response of benthic metrics to salinity was determined in accordance with the governing equations provided in Table 5-1 coupled with the SLR regression in a manner analogous to the SAV application. Figure 7-6 illustrates the steps which are described in the example which follows. Observed median flow conditions (not adjusted for athropogenic impacts) were used because the observed biota from which the relationships were derived represent specific locations within the system under observed flow conditions. ____________________________________________________________________________________________ Proposed Minimum Flows and Levels for Weeki Wachee River Technical Approach Page 106 of 164
