Flood — Marshall, Indiana

2018-02-20 to 2018-02-25 · near Teegarden, Marshall, Indiana

Event narrative

Damage occurred to several roads as a result of the record flooding from the Yellow River and associated drainage basin. Many county roads were closed for a period of time with even State Routes 30, 331 and 6 being impacted by flood waters. Nearly every town in the county suffered damage from the flood waters with Plymouth, Argos and Bremen suffering the most damage. Evacuations were necessary in some areas with water rescues due to rapid rise in the rivers. Preliminary damage estimates exceed 1.2 million dollars.

Wider weather episode

A slow release of a snow pack, containing one to over two inches of water, occurred in the days leading to the event which started the process of river rises in many areas. Low pressure tracked from northwest Iowa into northern Lower Michigan, which ushered in a rapid warmup and equally rapid release of any remaining water in the snow-pack. Several rounds of rain occurred between the 19th and 21st of February across the region, fed by record high precipitable water levels (by February standards) in the 1.3 to 1.5 inch range. A swath of four to six inches of rain fell northwest of a Logansport to Kendallville line. All these factors combined to cause extensive flooding on several rivers in the St Joseph, Kankakee and Upper Wabash river basins, with record crests occurring on some rivers. These water levels forced evacuations of homes and closure of businesses and schools, rescues from those driving into flood waters and an overwhelming of water treatment facilities in a few communities. While exact damage figures were not available at the time of entry of the data, preliminary data suggests values into the millions (possibly $10 million or higher).
