The U.S. Army Corps of Engineers has conducted a study of flooding frequency and severity on the Illinois River in Arkansas and in Oklahoma. The study will give you information of past floods and rainfall amounts as well as scenarios to control flood waters and to reduce the velocity of the water. Take home messages: Heavier rain is occurring in the watershed. Expanding riparian buffers is the most feasible way to control the velocity of flood waters. Detention ponds are not feasible and not recommended by the study.
