Current Surface Specific Conductance 1-Hour Levels

The map below shows the current highest surface specific conductance 1-hour levels measured in microsiemens per centimeter (µS/cm) for each of the river basins across Texas where surface specific conductance is measured by the TCEQ. More detailed maps showing the current 1-hour surface specific conductance levels measured at each site in a particular basin are available by clicking on the boxes on the map. These levels are based on data measured at the TCEQ's continuous water quality monitoring stations and may include data from local governments and private monitoring networks.

The latest imagery available is for Friday November 24, 2017 07-08:00 CST.
