The Klamath River flows some 250 miles from southern Oregon to Northern California. From its headwaters at Upper Klamath Lake, east of Medford, Oregon, the river rushes through trout habitat, forested mountains, farmland and salmon nurseries as it makes its way to the Pacific Ocean. Rather, the river usually rushes. But now, drought is desiccating almost the entire Klamath River basin, some 12,000 to 15,000 square miles. That’s an area approaching the size of the entirety of Massachusetts and Connecticut combined.
