Fair for fishing (70/100), from 6 available inputs. Supporting this: Wind 0 mph from the west-northwest. Morning hours (09:00 local). Working against it: Measured water temperature 38°F from a representative gauge 18.9 mi away. Provisional data. Air temperature 35°F. Not available from a verified source for this lake: pressure trend. Confidence is moderate (82%) because some inputs are unavailable or older than ideal.
Excellent for boating (99/100), from 4 available inputs. Supporting this: Wind 0 mph from the west-northwest. Gusts to 6 mph. Not available from a verified source for this lake: visibility and conditions, verified water access. Confidence is moderate (84%) because some inputs are unavailable or older than ideal.
Fair for sailing (60/100), from 4 available inputs. Supporting this: No active official alerts for this lake. Gusts exceed sustained wind by 6 mph, making the breeze puffy. Working against it: Wind 0 mph is light; expect limited sailing. Not available from a verified source for this lake: visibility. Confidence is high (88%).
Fair for kayaking (71/100), from 5 available inputs. Supporting this: Wind 0 mph from the west-northwest. Gusts to 6 mph. Working against it: Air temperature 35°F. Water temperature is 38°F (combined air+water: 73°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
Surface water measured at 38°F. Cold shock reflex presents an immediate drowning risk.
