65.5 FeetExtensive and severe flooding can be expected from above Klamath Glen to the Pacific Ocean including the towns of Klamath and Klamath Glen and US Highway 101. The forecast level is at the top of the levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground. High tides and strong, onshore winds amplify effects.
65.0 FeetSevere flooding is expected in the delta area, particularly US Highway 101 in the vicinity of Requa Road, the access road to Klamath Glen, and secondary roads. The forecast level is within 0.5 feet of top of levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground. High tides and strong onshore winds will amplify flooding effects.
64.0 FeetSevere flooding is the delta area is likely, particularly US Highway 101 in the vicinity of Requa Road, the access road to Klamath Glen, and secondary roads. The forecast level is within 1.5 feet of the top of the levee. Any persons living or working in areas protected by the levee should be prepared to take appropriate action and move to higher ground.
