Sara Thompson, a spokesperson for the Columbia Inter Tribal Fish Commission, said the high numbers of returning fish is excellent news for Columbia River tribes and fisheries. She said the improved numbers come from several factors, including "improved fish passage, good ocean conditions ... great work by the Nez Perce Tribe and Snake River fall Chinook."

Ratios of wild versus hatchery fish haven't been determined yet, but the number of wild fish expected to make it all the way to the Snake River may exceed hatchery numbers.

So far, 520,706 fall Chinook have passed the Bonneville Dam this year. A daily fish counter can be viewed here.
