Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 542.210

In order to further necessary investigations and studies for the maximum development of the Rogue River basin and watershed and to conserve established and potential uses thereof, and to facilitate full consideration of various projects to accomplish a coordinated and comprehensive development of the basin and watershed, the United States and its authorized agencies may construct in the Rogue River and on its bed dams and such other structures as the government deems necessary, upon compliance with the laws of Oregon. However, no dam or structure hereby authorized shall be placed in the Rogue River between the intersection of the river with the south line of section 10, township 34 south, range 1 west of the Willamette Meridian in Jackson County, and the confluence of that river with the Pacific Ocean, which would interfere with the free passage of fish up or down stream. No dam or other structure shall be constructed by any person in or on the bed of the Rogue River below its intersection with the south line of section 27, township 33 south, range 1 east of the Willamette Meridian, in Jackson County, except as authorized by this section.
