A study released today shows that breaching four federal dams on the lower Snake River could reduce barge and ocean container shipping operations on the Columbia-Snake river system, increase freight transportation costs, and add to highway and rail traffic.

Breaching of the four federal dams is one of several options under consideration to improve fish habitat and migration return rates for threatened or endangered salmon and steelhead runs in the Columbia-Snake river system.

The study focused specifically on the impacts of dam breaching on the regional transportation system, rather than the broader, national impacts explored in a recently released study by the U.S. Army Corps of Engineers and National Marine Fisheries Service.

"Breaching the Lower Snake River Dams: Transportation Impacts in Oregon" was jointly sponsored by the Port of Portland, Oregon Department of Agriculture, Oregon Economic and Community Development Department and the Oregon Department of Transportation. The study was conducted by HDR Engineering Inc., a leading architecture and engineering consulting firm with offices in Tigard, Ore., in association with Ogden Beeman & Associates Inc. and TW Environmental Inc., both of Portland.

If the earthen portions of the lower Snake River dams were removed, the HDR Engineering study found:

"Finding the best strategy for achieving recovery of endangered salmon is going to require taking many factors into account. This study makes clear that regional transportation impacts should be one of those factors," said Mike Thorne, Port of Portland executive director. "Without the lower Snake River as a link between the interior Northwest and the deep-water ports on the lower Columbia River, road and rail systems in the region will become more congested while the costs of shipping will increase and access for our region to world markets will decrease."
