Composite relative risk indices for dreissenid mussel introductions in the Missouri River Basin: scripts and output

This data product develops a composite relative risk index (CRR) for watersheds within the Missouri River Basin, a region in the U.S. on the front line of dreissenid spread. The CRR is developed using datasets in order to account for the direct and indirect damages from a potential infestation along with the risk of an infestation occurring with a HUC10 watershed. Included are indices calculated on a Missouri River Basin-wide scale, and indices calculated on an individual state basis. This dataset includes the code used to build the CRR dataset and generated geospatial output.
