Verified gage-height and water-temperature observations are not currently available for Lake Superior - Wisconsin South Shore in Wisconsin. LakeRadar does not substitute modeled values.
Small Craft Advisory issued October 9 at 12:55PM CDT until October 9 at 10:00PM CDT by NWS Duluth MN
Surface elevation benchmark above sea level (MSL) for Lake Superior - Wisconsin South Shore
Natural freshwater basin with seasonal hydrologic fluctuations
Deepest basin sounding across ~20,300,000 acres
Brisk (50–60°F) · Cold shock risk · Wetsuit recommended
No active telemetry gauge is currently mapped to Lake Superior - Wisconsin South Shore. Not available from a verified source for this lake.
NOAA GLERL GLSEA surface temperature at 46.612, -90.878 · Oct 8, 12:00 PM UTC
Historical daily time series not currently recorded for this monitoring station. Real-time continuous digital USGS sensors are prioritized for major floodway rivers.
Tributary runoff, precipitation, and snowmelt elevate the waterbody to its annual summer recreation pool.
Water levels remain stable for peak boating, public park ramps, sport angling, and shoreline swimming.
Regulated seasonal drawdowns or natural seasonal minimums occur to prepare for winter freeze-up and spring capacity.
No recent observation table entries recorded for this site. In-situ stage height is verified through annual bathymetric surveys and state environmental monitoring rather than continuous automated gauge feeds.
Current index calculated from verified local atmospheric, hydrographic & alert inputs.
Poor for swimming (35/100), from 5 available inputs. Supporting this: 1% chance of precipitation. Wind 5 mph from the northeast. Working against it: Measured water temperature 58°F. Provisional data. Cold water hazard: thermal protection recommended below 60°F. Water temperature is 58°F (below 60°F). Immersion requires thermal protection. Confidence is high (86%).
Continuous In-Situ Telemetry Notice: Active continuous automated telemetry stations are not currently installed directly within Lake Superior - Wisconsin South Shore. Not available from a verified source for this lake.
Official vertical datum, navigational perimeter geometry, and bathymetric basin contours are cataloged from official hydrographic surveys conducted by U.S. Geological Survey monitoring location defines this shoreline area.
