fish ladder annual maintenance schedule


Peak viewing times are listed below.  Even during peak times, you may not actually see Salmon in the Fish Ladder or Viewing Windows for a variety of reasons, such as low tides, hot weather, etc. 
Fish Ladder Viewing Room
Salmon Education Center 
Coho (Silver) - Average around 25,000 per year, peak viewing in September.  
Three species of Pacific Salmon pass through the Locks during the summer months and travel 40-50 miles upriver to spawn:
Chinook (King) - Average around 15,000 per year, peak viewing in August. 
 (See daily and annual salmon counts)
The fish ladder system is closed, drained, inspected and repaired as needed in mid-May and closed for 2 weeks or longer, check News or call visitor center for status.
Sockeye (Red) - Runs have been declining but remain the largest run.  Numbers vary widely,                                                  recent average around 30,000 per year,   Peak viewing mid-June to mid-July.
Fish ladder maintenance schedules carefully coordinate with both salmon migration seasons and ship traffic.
The new Salmon Education Center,  renovated with public donations, now offers improved seating, & ventilation, plus a videowall and interactive touchscreens to learn about the life cycle of the salmon.

Thanks to many generous donors, we are now working on adding educational exhibits to the viewing room.   There are still a few fish available to include your name on the Legacy Donor Wall.
