Peak Gusts: 20 mph. Moderate surface chop across main fetch.
Cold Shock Hazard: Life jackets are strongly urged for all vessel occupants across open water.
Ramp Accessibility: Local elevation datum referenced for safe boating operations on Kachess Lake.
Advisory Threshold: Official Lake Wind Advisories trigger when sustained winds reach 15 mph or waves exceed 3 ft.
Current index calculated from verified local atmospheric, hydrographic & alert inputs.
Excellent for boating (92/100), from 4 available inputs. Supporting this: Wind 5 mph from the northwest. No active official alerts for this lake. 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.
