Example of USGS streamflow conditions table

 

USGS Current Streamflow Conditions

Provides todays most recent discharge and gage height measurements for streamflow points in Nevada and Eastern Sierra

 

Example of USGS streamflow conditions map

USGS Current Streamflow Conditions Map

Average Streamflow for: 1 day | 7 day | Month

Map comparing recent streamflow to historical percentiles in Nevada and Eastern Sierra.

Example of USGS duration hydrograph

USGS Nevada 7-day Duration Hydrograph

Duration hydrograph of 7-day average runoff for streams in Nevada for last 3 water years.

Example of NRCS monthly streamflow table  

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.

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
  • 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
