Listed below are river and lake levels at monitoring stations for the past week. Click on any station name to get a month's worth of river levels at that station. These data are provisional; please see disclaimer regarding use of the data. To locate a station, use our interactive map. The river levels are given in feet above Mean Sea Level (MSL), which is roughly equivalent to the surveying datum NGVD 1929. These values show the elevation of the water surface above sea level, and not how deep the water is relative to the bottom. The water levels are normally posted within four hours of observation.
