Deschutes Canal-Lining Demonstration Project. Year 5 Durability Report. Upper Deschutes River Basin Water Conservation Program
The Deschutes Canal-Lining Demonstration Project is a cooperative effort among the Bureau of Reclamation, Deschutes River Basin irrigation districts in central Oregon, the Lugert-Altus Irrigation District in Oklahoma, and several geosynthetic lining manufacturers. The purpose of this study is to develop low-cost canal-lining technologies to reduce seepage over severe rocky subgrade conditions. The 22 test sections include combinations of geosynthetics, soil, concrete grout, chotcrete, elastomeric coatings, and sprayed-in-place foam. This report assesses the performance of the original 18 test sections after 5 years of service. This report also documents the construction of four additional test sections and assesses their performance after about 2 years of service. Pre- and post-construction ponding tests have generally shown that the concrete liners stop about 90 percent of the seepage in the short-term, while the geomembrane liners stop about 99 percent of the seepage.
