Poison Flat
Poison Flat, CA is located in the Sierra Nevada mountain range at an elevation of 7,000 feet. The average annual snowfall is around 350 inches, with an average peak snowpack of 90 inches in March. The nearby ski resorts include Dodge Ridge, Bear Valley, and Sierra-at-Tahoe. In recent years, the climate trends have shown a decrease in snowpack due to warmer temperatures and a shift in precipitation from snow to rain. This has resulted in a decrease in runoff and water availability for downstream hydrology constituents such as the Tuolumne River, the Cherry Creek, and the Lyons Reservoir. The snowpack is a vital source of water for the region, and a decrease in snowpack can lead to water scarcity and ecosystem imbalances. It is crucial to monitor and manage the snowpack to ensure a sustainable water supply for the region.

Mountain & avalanche safety
- Know before you go
- Check today's avalanche bulletin from the regional avalanche center before any backcountry / side-country travel. Conditions can shift dramatically between morning and afternoon on storm days.
- Carry the gear, know how to use it
- Beacon, shovel, probe. Practice companion rescue on a calm day, not during a real burial.
- Mind the weather window
- Heavy snow + wind builds wind slabs at ridgelines. The day after a storm is often the riskiest in the backcountry.
- Read the snowpack
- A weak, faceted, or wind-loaded snowpack — like the depth and trend shown above — is exactly what feeds slab avalanches. Dig a pit or check the bulletin before committing to steep terrain.

About Poison Flat
Where does the snow data for Poison Flat come from?
Snowpack depth, SWE, snowfall, and air temperature come from the NRCS SNOTEL station 697. Forecast comes from the NOAA / yr.no feed Snoflo's iOS app uses.
How often is the report updated?
NRCS SNOTEL stations report continuously (typically hourly). Snoflo refreshes throughout the day; check the "as of" timestamp on the snowpack hero card.
What's the difference between snowpack depth and SWE?
Snowpack depth measures how tall the snow is. SWE (snow water equivalent) measures how much WATER is in that snow. SWE matters more for hydrology and ski-season prediction since dry powder packs less water than wet/spring snow at the same depth.
How is "% of normal" calculated?
Today's snowpack is compared to the historical average snowpack on this calendar day across the station's full record. 100% = right on average; 130% = a big year; 60% = a thin year.
Can I get alerts when fresh snow hits?
Yes -- snow alerts are managed in the Snoflo iOS app. Favorite this station, set a snowfall threshold (e.g. "alert me when 6+ inches"), and you'll get a push the moment NRCS reports the crossing.
