Data describing a predatory fish invasion on a riverine food web Data describing a predatory fish invasion on a riverine food web
Catfishes are opportunistic feeders that are among the world's worst invasive species. Flathead catfish *Pylodictus olivaris* -- a large predatory catfish -- were first detected in the Susquehanna River, Pennsylvania, USA in 2002. Since then, they established a viable and rapidly growing population that is expanding its range throughout the river system. Although the predatory effects of...
Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits Grade and tonnage data for lithium, cesium, and rubidium pegmatite deposits
Pegmatites are a major host of global lithium, cesium, and rubidium resources. However, the existing grade and tonnage dataset for lithium pegmatites that was published in 1992 does not represent the current industry parameters used to delineate resources. There are no existing grade and tonnage datasets for cesium and rubidium. We present grade and tonnage data for lithium, cesium, and...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...

Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon
This map portrays the distribution of landforms along the Umatilla River in northeastern Oregon and covers a corridor 127 kilometers (km) long from the confluence of the Umatilla River with the Columbia River upstream to Meacham Creek. The map encompasses the valley bottom and extends about 1 km up the adjoining hillslopes. Map data are intended to support water quality and fisheries...
