How fish stocking works

What the DWR public stocking report tells you and what it does not, with numbers from the report itself.

What the report shows

DWR's public stocking report lists one row per stocking: the water, county, species, number of fish, their average length in inches and the date. It covers 2002 to today (59,777 records). DWR adds stockings after they happen. It does not publish future dates.

Fish sizes in 2025

DWR stocked 12,239,102 fish in 2,544 records in 2025. Grouped by the average length DWR reports:

  • Under 6 inches: 9,025,501 fish (74%).
  • 6 to 8 inches: 654,862 fish (5%).
  • 8 inches and longer: 2,558,739 fish (21%) in 1,621 records.

Our grouping by average length; DWR does not label sizes in the public report.

Timing

Timing tends to repeat for waters stocked every year. See what the records show about stocking schedules, and each water page for its own past pattern.
