Fish Counts

Please note:

The Washington Department of Fish and Wildlife and Muckleshoot Indian Tribal staff conduct fish counts as Lake Washington fisheries' co-managers. In recent years, numbers predicted by the Locks count data have been much higher than what is observed reaching the hatcheries and spawning grounds. There are many potential reasons for this discrepancy, but right now the cause(s) are unknown.

For more detailed count data, click the link in the table below. Current and historical data appear in the "Counts" and "Historical" tabs, respectively.

  • This data is preliminary and subject to change as the season progresses.
  • Data displayed here is updated weekly and reflects a weekly summary for the previous seven days.
