California's extreme drought is putting a serious wrench in salmon swimming routes.
California is suffering a record-breaking drought and 75% of the state is currently in "extreme" or "exceptional" drought conditions. As a result, seasonal water activities are taking a big hit. White-water rafting trips and fishing tournaments have been canceled. Tourism is down. And now, migrating Chinook salmon are even being transported to the Pacific Ocean by truck because the river swim is too perilous.
