BUILDING STRONG® 2018 Flooding
Little River: Two of the four lakes in the Little River system, Gillham Lake and Dierks Lake, reached their pool of record. Both have been in operation since 1976 (42 years).
Arkansas River: MS River was forecasted to reach level that would cause backflow into Arkansas River. Stop logs were placed to protect lock miter gates at Lock 1, but MS River crested approx. 1’ short of this condition.
