Name of study:

Monitoring of Delta Smelt Abundance and Distribution
Delta Smelt Spawning Season Monitoring

Purpose/Objective

Monitor and provide information on delta smelt abundance in the Sacramento-San Joaquin River Estuary. Provide important distributional information during spawning migrations.

Detect adult delta smelt spawning migrations. Conduct larval fish surveys to determine the timing, distribution, and abundance of delta smelt larvae and their food supply. Estimate larval delta smelt fish losses, determine the magnitude of entrainment of both larval and pre-juvenile delta smelt at NBA, CVP and SWP intakes.

Sources of Data:

Files containing data collected specifically for this program element are still under construction. Currently five other program elements, that are listed below, provide the primary source of this program element. Click on these links to find out more about each program element, to read the Metadata, Format, and Reference files, or to download data.

  • Midwater Trawl Survey - Detect adult delta smelt spawning migrations. Provide abundance and distribution information which has been incorporated into the USFWS Biological Opinion for the operation of the CVP and SWP and the recovery plan for delta smelt created by the Delta Native Fishes Recovery Team.
  • North Bay Aqueduct Entrainment Monitoring - Estimeate and evaluate the losses of eggs and larval fish. Monitor the abundance and distribution of larval delta smelt in Barker and Lindsey sloughs.
  • Southern Delta Entrainment Monitoring - Estimates larval delta smelt fish losses, at CVP and SWP intakes, determines the magnitude of entrainment of both larval and pre-juvenile delta smelt at CVP and SWP intakes.
  • Striped Bass Egg and Larva Survey - Determines the timing, distribution, and abundance of delta smelt larvae and their food supply throughout the Estuary.
  • Summer Townet Survey - Provide abundance and distribution information which has been incorporated into the USFWS Biological Opinion for the operation of the CVP and SWP and the recovery plan for delta smelt created by the Delta Native Fishes Recovery Team.
