Aquatic invasive species are often transported between water bodies on boats or boat trailers, thus they are considered one of the primary vectors for new introductions of invasive species to a water body. This data set contains geographic positioning system locational data for boater access points, use data (i.e. recreational, fishing), water quality measurements (e.g. calcium concentrations, pH), risk assessment data, and other physical attributes (i.e. size, elevation) where available within the Columbia and Snake Rivers and throughout the Columbia River Basin. This work builds on an earlier body of work by Wells et al. 2011, Prioritizing Zebra and Quagga Mussel Monitoring in the Columbia River Basin (PDF link...
