Data

Real-time water levels and long-term statistics for lakes and reservoirs in Wisconsin. Lake data are collected and stored as continuous time-series data from automated recorders.

USGS 01323500 Great Sacandaga Lake at Conklingville NY Great Sacandaga Lake Surface Elevations year-to-date

USGS 01304200 Orient Harbor at Orient NY --Water elevation, astronomical-tide elevation, and residual water level. Graph updated every 15 minutes.

The Mohawk River between New York State Barge Canal Locks 7 and 8 near Schenectady, NY is susceptible to ice jams during periods of river-ice break-up. Ice jams in this reach typically form at channel constrictions, bridge piers, lock and dam structures, and sections with a reduced floodplain.

The EROS data archive contains a vast array of satellite imagery, aerial photos, digitized maps, elevation and land cover products, and much more. Most are easily downloadable via the internet.

The animations are not a prediction of sea level rise, but rather illustrate areas of low elevation by a blue color simulating coverage by water. The numbers of people in those areas are tabulated.

The Real-Time Groundwater Level Network contains data typically recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. All real-time data are provisional and subject to revision.

Reports of ash fall are important to us; we use your observations to assess the character and size of an eruption plume. We report these data to the National Weather Service so they can keep their Ashfall Advisories current. Additionally, reports of NO ashfall during an eruption with expected ashfall are also important to us.
