Download long term data as csvNote: CSV data will include any outlying values that have been ignored by our graphing system as probably erroneous (eg, because they are ridiculously high compared to the values either side of them). It is your responsibility to filter these out if necessary.
Important! If you are planning to retrieve the csv data automatically, you must read and understand the limitations on the data and its availability.
Please note: Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
