49 Summer 2016 Proceedings www.uscg.mil/proceedings Nearly 85 years ago, Tidewater Transportation and Termi- nals helped pioneer commercial transportation on the upper Columbia/Snake River (CSR), opening up one of the nation's most isolated regions to the markets of the world. Columbia/Snake River System In the early 1930s, commodity transport via rivers in the Columbia River basin took a back seat to the railroads until the U.S. Army Corps of Engineers (USACE) completed the Bonneville Dam in 1938, then the McNary Dam in 1953. Today, eight hydroelectric dams and navigation locks pro- vide tug and barge companies a 465-mile navigable water- way between Portland, Oregon; and Lewiston, Idaho; allow- ing the Columbia/Snake River system to annually transport more than 46 million tons of cargo, including grain, refined petroleum products, fer- tilizer, containers, wood products, and special project cargoes. 1 Economic Impact According to the Pacific Northwest Waterways Association, the regions along the CSR are poised to experience tremendous growth over the next 15 years, making the Columbia River basin econo- mies even more reliant on the ability to efficiently flow that growing commerce up and down the system. Hence, Columbia/Snake River system stake- holders (including companies such as Tidewater, grain growers/co-ops, ports, the energy industry, exporters, and others) look to the U.S. Army Corps of Engineers to maintain lock and dam integrity. The federal government also invested in major maintenance repairs for the locks and dams along the CSR in 2010. While this was good news for the longevity of the system, the maintenance closed the system for nearly four months. Transforming the Tide A look at the Columbia/Snake River system — past, present, and future. by Ms. Jennifer r iddle Public Information Officer Tidewater Transportation and Terminals Regions Vessels that pass through the eight Columbia /Snake River locks travel nearly 750 feet above sea level. The Columbia River John Day lock lifts 105 feet and is the deepest lock of its type in the nation. The Ice Harbor and Lower Monumental dams on the Snake River each lift 100 feet. In comparison, Mississippi River locks typically provide 10 to 25 feet of lift. Graphic courtesy of the Pacific Northwest Waterways Association. U.S. Army Corps of Engineers statistics. "As I reflect upon my life on the river, I think of the old river captains and pilots who opened the wild Columbia. They had the vision to foresee the potential of the river. They fought for the development of the dams and navigation locks that have given us slack water navigation from Lewiston, Idaho, to the sea. Their incredible skill and courage is an inspiration." — Captain Lewis S. Russell, Jr., past president Tidewater Transportation and Terminals
