There are 54 streamgage sites collecting 5-minute continuous gage height data in the Charlotte-Mecklenburg Network. Of these 54 sites, 44 compute streamflow data as well.

Most sites use line-of-site radios to transmit the data to the USGS within minutes after the data is recorded. These data are loaded in the USGS database and available online soon after.
