377 This is the critical stage for the McLean Bottom Levee. This is an extremely dangerous and life threatening situation.
373 This is the critical stage for the Lower Hartman Bottom Levee. This is an extremely dangerous and life threatening situation.
370 This is the highest stage experienced since the completion of the navigation system in 1969. This is an extremely dangerous and life threatening situation.
367 Highways 309 and 288 northwest of Paris in Logan County are inundated by backwater up Six Mile Creek. Backwater flooding will spread westward into Franklin County at higher stages. This is an extremely dangerous and life threatening situation.
365 County Roads 228 and 4 south of Coal Hill in Johnson County are inundated. Roads northeast of Scranton in Logan County are inundated by backwater up Cane Creek. This is an extremely dangerous and life threatening situation.
363 Patrolling of McLean Bottom Levee in Logan County and Lower Hartman Levee in Johnson County begins.
360 Flooding spreads over more than 4,000 acres in Franklin and Logan Counties. Numerous gas fields are flooded. Some agricultural lands in Johnson County also are flooded.
357 Flooding affects agricultural use lands along the river downstream of the lock and dam in Franklin County. Gas fields are also subject to flooding downstream. Equipment and livestock should be moved to higher ground.
