Merged Isochlor, 2014

This is a merged set of Isochlor line features into single feature class compiled from the original series of individual 2014 Isochlor data layers. Approximate 250 mg/L isochlor for Broward, Palm Beach, Martin, St. Lucie, Lee and Collier Counties. Well and chloride data were obtained from USGS and SFWMD records. The line marks an approximation of the farthest inland extent of the saltwater interface as defined by the 250 mg/L chloride concentration and/or the farthest inland extent of saline surface water. The isochlor is based on the average of available chloride values for the period of March/April/May 2014. Chloride and well data from the SFWMD have been furnished by Permittees and have not been validated. Chloride and well data from the USGS are available via http://waterdata.usgs.gov/nwis.
