Flood Impacts & Photos

22	This level corresponds to the last occurrence of major flooding on December 31, 1990. Roads and low lying structures near the river from Connersville to Laurel are flooded.
21.5	This is similar to the FEMA 1 percent flood. Major flooding occurs along the West Fork of the Whitewater River in southern Fayette and northern Franklin Counties, including the towns of Alpine, Nulltown and Laurel. Homes near between Dora Street and the river on the east side of Connersville incur flooding. Much of State Route 1 is covered as well as secondary roads near the river. Structures impacted in Laurel are mainly along and south of Pearl Street.
21	Lowland flooding worsens in Alpine, Laurel and Nulltown. Water extending on to some county roads in southern Fayette and northern Franklin Counties will make these low-lying roads impassable.
20	Water spills across State Route 1, one half mile north of the Indiana State Police Post in Connersville. Flooding also extends to the east side of Connersville in low-lying areas. Flooding worsens along low-lying roads and agricultural areas in Alpine and Nulltown.
19	Water extends further out of the banks of the West Fork of the Whitewater River with some water extending onto county roads near Alpine and Nulltown.
18	Flood water encroaches toward county roads, and flooding of low-lying agricultural land continues in Fayette and northern Franklin Counties.
17	Flooding of low-lying agricultural land can be expected in southern Fayette County.
