Partnerships and process for improving boater safety: a case study of transient moorage facilities on the Columbia River

The increase in recreational boaters in Oregon, concurrent with a significant increase in population statewide, will lead to higher usage of the Columbia. River by both recreational and commercial vessels. The orderly development of a network of transient moorage facilities along the river will (1) assist in reducing conflicts between recreational boaters and commercial vessels, (2) provide a safe, pleasant experience for recreational boaters, (3) contribute to the efforts of local communities in economic development, and (4) minimize adverse impact on the environment, particularly riparian habitat and water quality. A three-year case study of approximately 465 miles of the Columbia River found 93 potential transient moorage sites. Sites were evaluated on distance from potential/existing moorages (optimal spacing=1 site/15-20 miles), navigational depth, protection from wind and currents, user appeal (i.e. scenic area, presence of wildlife, geologic location of interest, near historic point of interest, etc.), and level of disturbance to sensitive riparian and aquatic habitat for fish, wildlife, and plant species predicted in site development. A total of 54 sites were determined satisfactory or better under this classification system, and would allow an increased number of recreational boaters to more safely explore the Columbia River
