Provides current streamflow conditions and five day projected streamflow.
Historic Streamflow Data Table: Displays period of record, monthly streamflow data table for points important to Nevada. Unless otherwise stated all data are obtained from the USGS.
"ADJ" indicates streamflow adjusted for reservoir storage or diversions. More information about adjustments is provided below.
"DISC" indicates streamflow point does not have data from recent years because the gage was discontinued.
Historic Streamflow Data Graph: Displays period of record, monthly streamflow data hydrograph for points important to Nevada. Unless otherwise stated all data are obtained from the USGS.
"ADJ" indicates streamflow adjusted for reservoir storage or diversions. Additional information about adjustments is provided below.
"DISC" indicates streamflow point does not have data from recent years because the gage was discontinued.

Streamflow Adjustments
Lake Tahoe Net Inflow (externally adjusted by US Water Master*) = Lake Tahoe storage change + Lake Tahoe Release. Net inflow used due to complexities with estimating Lake Tahoe evaporation and precipitation.
Marlette Lake Inflow = Marlette Lake Inflow, observed + Marlette Lake storage change
Donner Lake inflow (externally adjusted by US Water Master*) = Donner Lake storage change + Donner Lake Release + Lake Evaporation – Lake Precipitation
Martis Creek Reservoir inflow (externally adjusted by US Water Master*) = Martis Creek Reservoir storage change + Martis Creek Reservoir Release + Lake Evaporation – Lake Precipitation
Prosser Creek Reservoir Inflow (externally adjusted by US Water Master*) = Prosser Creek Reservoir storage change + Prosser Creek Reservoir Release + Lake Evaporation – Lake Precipitation
Independence Lake Inflow (externally adjusted by US Water Master*) = Independence Lake storage change + Independence Lake Release + Lake Evaporation – Lake Precipitation
Stampede Reservoir Local Inflow (externally adjusted by US Water Master*) = Stampede Reservoir storage change + Stampede Reservoir Release + Lake Evaporation – Lake Precipitation – Independence Lake Release + Sierra Valley Diversion
Boca Reservoir Local Inflow (externally adjusted by US Water Master*) = Boca Reservoir storage change + Boca Reservoir Release + Lake Evaporation – Lake Precipitation – Stampede Reservoir Release
Little Truckee River above Boca Reservoir (externally adjusted by US Water Master*) = Independence Lake Inflow + Stampede Reservoir Local Inflow + Boca Reservoir Local Inflow
Truckee R above Farad Sidewater (externally adjusted by US Water Master*) = Truckee River at Farad, observed – Boca Creek Reservoir Release – Prosser Creek Reservoir Release – Donner Lake Release – Martis Creek Reservoir Release – Lake Tahoe Release
Truckee River at Farad (externally adjusted by US Water Master*) = Donner Lake inflow + Martis Creek Reservoir inflow + Prosser Creek Reservoir Inflow + Independence Lake Inflow + Stampede Reservoir Local Inflow + Boca Reservoir Local Inflow + Truckee R above Farad Sidewater
East Walker River near Bridgeport = East Walker River near Bridgeport, observed + Bridgeport Reservoir storage change
L Humboldt R nr Paradise Valley (2) = L Humboldt R nr Paradise Valley + Chimney Creek Reservoir storage change
Owyhee River near Gold Creek = Owyhee River near Gold Creek + Wildhorse Reservoir storage change
Colorado R at Glen Canyon Dam (aka Lake Powell Inflow) = externally adjusted by Bureau of Reclamation for major upstream reservoirs, but not trans-basin diversions to Missouri or Rio Grande
