Real-time wind speeds, peak gusts, and surface chop forecasts from NOAA National Weather Service, verified public boat launches, USGS surface water telemetry, and Utah state boating regulations for Jordanelle Reservoir (Utah).
Hydrologic Outlook issued October 8 at 3:13PM MDT by NWS Salt Lake City UT
Peak Gusts: 9 mph. Moderate surface chop across main fetch.
Cold Shock Hazard: Water is below 60°F. Immediate cold shock hazard upon submersion. USCG life jackets essential.
Ramp Accessibility: Local elevation datum referenced for safe boating operations on Jordanelle 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.
Good for boating (86/100), from 4 available inputs. Supporting this: Wind 5 mph from the southeast. Gusts to 8 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.

Surface chop expands with sustained wind duration across Jordanelle 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 Jordanelle 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.

Fair for kayaking (61/100), from 5 available inputs. Supporting this: Wind 5 mph from the southeast. Gusts to 8 mph. Water temperature is 51°F (combined air+water: 102°F). Cold shock hazard: sudden immersion below 55°F poses serious risk. Confidence is high (90%).
