Sand boils observed during recent floods
During the recent flood event, numerous sand boils were observed adjacent to levees along the Wabash River. This sand boil was observed near the landside levee toe of the Gill Township, Indiana, Levee System. A sand boil occurs when water passing under a levee erupts through the ground surface on the landward side of the levee.
