Real-time wind speeds, peak gusts, and surface chop forecasts from NOAA National Weather Service, verified public boat launches, USGS surface water telemetry, and Colorado state boating regulations for McPhee Reservoir (Colorado).
Hydrologic Outlook issued October 9 at 10:53AM MDT by NWS Grand Junction CO
Peak Gusts: 13 mph. Moderate surface chop across main fetch.
Cold Shock Hazard: Life jackets are strongly urged for all vessel occupants across open water.
Ramp Accessibility: Water level referenced at 6,929 ft MSL for launch ramp clearance across public access points.
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.
Poor for boating (44/100), from 4 available inputs. Supporting this: Wind 10 mph from the south. 0% chance of precipitation. 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.

Surface chop expands with sustained wind duration across McPhee Reservoir's open water fetch. Early morning hours typically offer the calmest navigation before thermal afternoon winds develop.
Individual boat ramp GPS coordinates are currently being cataloged for McPhee Reservoir. Public launches are managed by state, county, or local park authorities.
Ramp operational status and courtesy dock availability are subject to seasonal water level shifts and lake management authority guidelines.
