The Massachusetts-Rhode Island office of the New England Water Science Center has transitioned to a new data management software package. While you may not notice this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and resolving them as quickly as possible. For more information contact Richard Verdi at rverdi@usgs.gov or 508-490-5064. See the December 8th news entry at: https://help.waterdata.usgs.gov/news
