Provides wrapper to turn the hy_stn_regulation table in HYDAT into a tidy data frame of station regulation. station_number and prov_terr_state_loc can both be supplied. If both are omitted all values from the hy_stations table are returned.

hy_stn_regulation(
  station_number = NULL,
  hydat_path = NULL,
  prov_terr_state_loc = NULL
)

Arguments

station_number

A seven digit Water Survey of Canada station number. If this argument is omitted, the value of prov_terr_state_loc is returned.

hydat_path

prov_terr_state_loc

Province, state or territory. If this argument is omitted, the value of station_number is returned. See unique(allstations$prov_terr_state_loc). Will also accept CA to return only Canadian stations.
