Sand Lake wind forecast
Hourly wind, gusts, and direction for the next 7 days with a small-craft sailing score for every hour — find the window, then rig for it.
How the score works. Every hour gets 0–10 points: full marks for sustained wind between 6 and 16 knots, with deductions for gust factors above 1.5× sustained wind, high rain probability (thunderstorm risk), and cold air that raises capsize stakes.
Lake wind is local. Thermal builds on sunny afternoons, katabatic draining at dusk, and channeling between hills all mean the modeled numbers can run a few knots either side of what you feel on the water — treat this as a planning tool, not a gospel.
Sand Lake water level
Gage height recorded at USGS gauge 06470992, refreshed every 15 minutes to 1 hour depending on the sensor.
Gage height history
Gage height · USGS gauge 06470992
Reading the chart. This gauge reports gage height — the depth of water above the sensor reference point, not absolute elevation. Trends matter more than the absolute number: a falling trend means shrinking launch depth.
Water levels respond to dam operations, irrigation drawdown, snowmelt, and recent rainfall. For launch decisions, combine the trend here with the wind forecast — low water plus strong wind makes steep, tired ramps.
Sand Lake fishing
Solunar feeding windows and live water temperature from the USGS gauge, plus hour-by-hour fish activity for the next two days.

Reading the radar
- Blue→green→yellow→red = light → heavy precipitation. Green already means small-craft weather is building; red means get off the water.
- Drag the slider past “now” for RainViewer’s nowcast — a 30-minute radar extrapolation, handy for timing a last reach before the cell arrives.
- Radar is precipitation only: it will not show the clear-air gust fronts that precede thunderstorms. Combine with the hourly forecast rain-probability column.

Water level data comes from the USGS gauge above; wind is modeled for the lake’s coordinates by Open-Meteo. Always confirm conditions locally before launching — mountain lakes in particular can build afternoon winds fast.
