Description: This is a merged set of Isochlor line features into single feature class compiled from the original series of individual 2024 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 maximum chloride value for the period of March/April/May 2024, with minor exceptions (denoted by an * at the end of the well table at the bottom of the published maps).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/nwisand may also be available in the District’s DBHYDRO database https://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu.The chloride wells used for this project are compiled in a separate point feature class called, "Chloride Concentration Control Points, 2024".

Description: This is a merged set of Isochlor line features into single feature class compiled from the original series of individual 2009 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 April/May 2009. 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. The original isochlor line was created in 2010.Version 1.1, March 03, 2015: The original isochlor was updated in 2014/2015 to incorporate new and corrected data, as well as a better understanding of the saline surface water.Version 1.2, May 08, 2015: Update at the S13 structure in Broward County based on corrected data. July 15, 2015: The original isochlor was updated in 2014/2015 to incorporate new and corrected data.

Description: This is a merged set of Isochlor line features into single feature class compiled from the original series of individual 2019 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 maximum chloride value for the period of March/April/May 2019, with minor exceptions (denoted by an * at the end of the well table at the bottom of the published maps).Chloride and well data from the SFWMD have been furnished by Permittees and have not been validated.
