17.7 .
15.5 Widespread, major flooding occurs with numerous roads and streets inundated and impassable. The river levels rise to the base of bridges resulting in flooding of bridges or bridge approaches.
15.2 This level represents a flood that has a 2-percent chance of being equaled or exceeded in any given year. For more information click here.
15 There is major flooding along the river including damage in Henderson and Brighton.
13 There is significant damage to agricultural lands along the river.
11.1 The river overflows its banks causing flooding downstream of Brighton and begins to affect agricultural lands. This level represents a flood that has a 10-percent chance of being equaled or exceeded in any given year. for more information click here.
