Name: Saltwater Interface (2024)

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 7 0;"><SPAN>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 </SPAN><SPAN>of the published maps</SPAN><SPAN>).</SPAN><SPAN /><SPAN>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 </SPAN><A href="http://waterdata.usgs.gov/nwis" STYLE="text-decoration:underline;"><SPAN><SPAN>http://waterdata.usgs.gov/nwis</SPAN></SPAN></A><SPAN><SPAN>and may also be available in the District’s DBHYDRO database </SPAN></SPAN><A href="https://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu" STYLE="text-decoration:underline;"><SPAN><SPAN>https://my.sfwmd.gov/dbhydroplsql/show_dbkey_info.main_menu</SPAN></SPAN></A><SPAN>.</SPAN></P><P STYLE="margin:0 0 7 0;"><SPAN>The chloride wells used for this project are compiled in a separate point feature class called, "Chloride Concentration Control Points, 2024". </SPAN></P></DIV></DIV></DIV>
