Current index calculated from verified local atmospheric, hydrographic & alert inputs.
Very Poor / Avoid for swimming (19/100), from 5 available inputs. Supporting this: No active official alerts for this lake. 1% chance of precipitation. Working against it: Measured water temperature 49°F from a representative gauge 20.2 mi away. Provisional data. Immersion shock hazard: water below 55°F poses severe cold shock and rapid hypothermia risk. Air temperature 40°F. Water temperature is 49°F (below 55°F). Severe cold shock and hypothermia hazard upon immersion. Confidence is moderate (75%) because some inputs are unavailable or older than ideal.
