What Floods at Each Level
22.5 ft
Water reaches the bottom of the Highway 281 bridge.
21.5 ft
The Wood River Diversion Levee will be topped in several locations with flood waters spilling over into businesses located along the levee especially along the south side of the river. Major property damage is expected if the levee were to fail.
20 ft
The Wood River will be within 1.5 feet of topping the levee at the Wood River Diversion on the south side of Grand Island. Damage to the levee and some flooding along the levee will be possible.
19.4 ft
Water reaches the bottom of the railroad bridge downstream of Highway 281 resulting in backwater rises on the west side of the railroad bridge. The rising backwater will quickly begin flowing through the low point in the levee on the north side of the railroad bridge unless this low spot has been previously sandbagged.
18 ft
The water level will be within 1.5 feet of reaching the bottom of the downstream train bridge. Once the water level reaches the bottom of the train bridge there will be increasing backwater just upstream of the train bridge and water will quickly reach the low spot in the levee near the train bridge. Sandbagging of the low spot in the levee near the train bridge will be required prior to reaching a stage of 19.5 feet to protect the levee.
