Excellent for fishing (92/100), from 5 available inputs. Supporting this: Wind 5 mph from the east. 0% chance of precipitation. Not available from a verified source for this lake: pressure trend, water temperature. Confidence is moderate (74%) because some inputs are unavailable or older than ideal.
Excellent for boating (98/100), from 5 available inputs. Supporting this: Wind 5 mph from the east. Gusts to 7 mph. Not available from a verified source for this lake: verified water access. Confidence is high (89%).
Good for sailing (86/100), from 5 available inputs. Supporting this: Gusts are within 2 mph of sustained wind, so the breeze is steady. No active official alerts for this lake. Confidence is high (91%).
Excellent for kayaking (97/100), from 5 available inputs. Supporting this: Wind 5 mph from the east. Gusts to 7 mph. Confidence is high (90%).
This swimming outlook uses a MODELLED water temperature, not a verified sensor reading. Treat it as a rough guide, not a measurement, especially for cold-shock risk.
