*Water level and current data provided by USGS are verified yearly for periods beginning October 1st. Final data will be added once verified. For provisional data after 9/30/16, please visit the link in the file header.

Tivoli Bays stations (North, South, and weather) are in the process of being re-added to the HRECOS network. To access real-time and historical data for these stations in the meantime, please visit http://cdmo.baruch.sc.edu/get/landing.cfm
