Summary General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The West of Morrilton Levee is a federally authorized non-federally operated and maintained rural flood protection project. The West of Morrilton Levee Local Protection Project (LPP) was authorized by the Flood Control Act of December 22, 1944. The system is a 13.4 mile earthen levee, which includes 15 drainage structures. Construction of the original West of Morrilton Levee was completed in August 1951. The West of Morrilton Levee includes three segments, namely the Pope County Levee Drainage District No. 2 (Stations 0+00 – 410+25) and the Conway County Levee District Nos. 3 and 7 (Stations 410+25 – 710+55). The West of Morrilton Levee is located generally on the left bank of the Arkansas River in Pope and Conway Counties, Arkansas. The levee begins on high ground approximately three miles south of Atkins, Arkansas and immediately north of Galla Lake, continues south approximately 2.5 miles towards the left bank of the Arkansas River, then southeast along the left bank of the Arkansas River to a point immediately upstream from the mouth of Point Remove Creek. The West of Morrilton Levee System primarily serves as flood damage reduction for approximately 20,000 acres of a mostly agricultural area. Failure of the earthen levee would result in the flooding of agricultural fields and farm structures, as well as a few residences located on the protected side of the levee along its eastern limits. A levee failure would result in property damage and potential loss of life. The Pope County Levee and Drainage District #2 begins at Station 0+00 and 410+25 (border of Conway County and Pope County). There are a total of four drainage structures in this segment: a double 42” CMP (Station 90+00); a triple 42” CMP (Station 323+50) and two double 36” CMP (Stations 169+50 and 398+95).
Performance & Condition General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
PLEASE NOTE: The following Risk Characterization is a description of risk associated with this levee system. It is currently undergoing review and may be updated in the future. The LSOG considers the risk associated with the Pope County Levee and Drainage District No.2 Segment (LST ID 3408) to be low (LSAC 4) for Prior to Overtopping due to the potential for poor performance but very low associated consequences and also to be low (LSAC 4) for Overtopping due to relatively infrequent likelihood of overtopping and very low associated consequences. The levee is not expected to perform well under significant loading. It has a history of poor performance with loads well below the top of levee and the potential for closure systems to either not be set or malfunction is high. The conditions of the culverts are questionable as well. All these concerns are offset by the fact that the potential for loss of life is negligible and the potential economic damages are very low.
