What we learned:
-We were on the Zig Zag River which feeds into the Sandy River, which feeds into the Columbia River
-The salmon we saw were Spring Chinook
-2 million salmon travel up the Columbia River annually
-16 years ago on 500,000 made it up the Columbia
-Wild salmon have stronger DNA than hatchery salmon
-Fish biologists only allow wild salmon to migrate upstream
-Hatchery salmon have no adipose fin
-Female salmon lay ~4000 eggs, only 1 adult makes it back!
~500 salmon make it back to the Zig Zag River, which means there had to be ~2 million eggs to begin with!
