Lots of environmental conditions affect when the salmon arrive at Lower Granite Dam. Fish and Game opens the season in late April to make sure that in years when the run is early, anglers are able to fish for the salmon. In 2001, a year with a large return, more than 38,000 Chinook salmon had been counted at Lower Granite Dam by this date. The run appears to be late this year. Only 25 salmon have been counted crossing Lower Granite Dam through April 24 this year. But the recent five-year average count for the same date is 497 salmon counted. Even if the run is not late, we typically don't see many salmon at Lower Granite Dam by this date anyway.
