Project Description

The project consists of repairing the principal spillway outlet structure. Severe erosion of the pipe has resulted in aggregate being exposed internally and externally, and has decreased the flow capacity. If not repaired, potential failure of the principal spillway pipe could occur. The principal spillway pipe will be repaired by slip lining the existing pipe with a high strength polyethylene pipe. The voids between the two pipes will be filled with grout to make a water tight seal.

Introduction

The 36-acre reservoir provides flood protection for the City of Waldron, nine farms and 1,440 acres in the watershed. Site 4 is directly upstream of Site 5, a rural water supply reservoir, and can provide additional water for the area if needed. Once the repair is completed, benefits for the citizens include public health and safety improvements. Water quality will be improved by reducing sediment in Sites 4 and 5. Utilizing funding through the American Recovery and Reinvestment Act for Site 11, will also ensure the site continues to provide $40,134 of flood prevention annually. The site is one of 16 flood water retarding structures in the Poteau River Watershed.
