For Water Level Data, the user can retrieve up to a maximum of one month worth of six minute data. The rest of the data sets can be retrieved up to a maximum of one year except for the high/lows and the daily mean data which have a maximum of five years.
A valid retrieval date for the verified data would be going back to the first of the current month, then two months back. For example, if today's date is March 2nd or March 29th, start with March 1st and subtract two months. The most recent date available for data extraction would be January 1st.
* Note: The Energy Policy Act of 2005 changed the start/end dates of Daylight Saving Time. Starting in 2007, Daylight Saving Time will begin on the 2nd Sunday in March and end on the 1st Sunday in November. The predictions provided have been adjusted for Daylight Saving Time based on these criteria.
