Real-time wind speeds, peak gusts, and surface chop forecasts from NOAA National Weather Service, verified public boat launches, USGS surface water telemetry, and Wyoming state boating regulations for Big Sandy Reservoir (Wyoming).
Peak Gusts: 9 mph. Light surface ripple; smooth navigation.
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 Big Sandy Reservoir.
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.
Very Poor / Avoid for boating (27/100), from 4 available inputs. Supporting this: No active official alerts for this lake. Working against it: Gusts to 35 mph. The forecast mentions thunderstorms, which carries a risk penalty. 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.
