Important Note: As finalized data for the previous month is not received until the 7th of the following month, we do not have finalized flow data for the past month until then. We have no current finalized flow data.
Before this time you may view the previous month's preliminary daily data in either the last two week report or view archived versions of this file in the ftp flow spill archive.
