Arguments

parameterCd

override_error

Logical parameter that allows users to run this function during the final stages of NWIS decommission. NWIS servers will be taken offline February 22nd, 2027. Setting this parameter to TRUE should only be used as a tool to convert readNWIS to read_waterdata functions.
