Case Study: Lake Ogletree Spillway Modifications


Case Study Overview

Project: Lake Ogletree Spillway Modifications
Location: Auburn, AL, United States
Project Type: Slope Stabilization
Application: Spillway Protection
ProductS Used: ARMORMAX®

Photo showing construction of new spillway and weir, where erosion protection was needed.


A new spillway and weir were put in lace in Lake Ogletree to help regulate the flow of the river. The project aimed to replace an existing 75-year-old spillway and increase the lake's water-holding capacity, which is the city's main water supply. The approach to the weir was in need of erosion protection as water would be flowing through it.


ARMORMAX® was utilized along the bottom and sides of the approach for spillway protection and bank armoring. ARMORMAX is composed of High Performance Turf Reinforcement Mats (HPTRMs) and Engineered Earth Anchors™ that work together to lock soil in place and protect against hydraulic stresses.

Approximately 8,000 yards of ARMORMAX® was installed along the sides and bottom of the approach to stabilize slopes, provide bank armoring, and protect the spillway from erosion as the new weir was put in place.
