The river distance between the ocean and the weir. Column "river" provides river or weir name and "river_distance_m" provides the distance in meters. Distances were provided in original data sources or estimated from google maps as detailed in the supplemental information accompanying the article. In some cases river distance could not be determined, in these cases the "river_distance_m" column is left blank.
