The NYWSC Observing Systems Division Troy office is testing the use of on-hand conductivity probes to measure stream discharge utilizing salt dilution methodology. Salt dilution is a well-researched technique in academic fields but thus far has not been widely used within the USGS. Currently, USGS offices in the Southeast Region are testing the use of specialized systems that have demonstrated accuracy but may pose a financial barrier to their wider adoption. By utilizing conductivity probes that may be readily available to hydrographers these financial barriers can be circumnavigated while maintaining accuracy. Demonstrating that on-hand equipment can be used to make reliable salt dilution measurements adds an accessible tool for hydrographers to collect the highest quality data at sites and conditions where traditional methods fall short.
