High-resolution geophysical mapping of Lake Powell in the Glen Canyon National Recreation Area in Utah and Arizona was conducted between October 8 and November 15, 2017, as part of a collaborative effort between the U.S. Geological Survey and the Bureau of Reclamation to provide high-quality data needed to reassess the area-capacity tables for the Lake Powell reservoir. Seismic data collected during this survey can help to define the rates of deposition within the San Juan and Colorado Rivers, which are the main inflows to Lake Powell. These new data are intended to improve water budget management decisions that affect the natural and recreational resources of the reservoir. Multibeam echosounder bathymetry and...

Two models of fire risk are presented here. One shows risk of natural fire based on abundance of tamarisk and native trees only. The other shows risk of all fire, which includes abundance of tamarisk and native trees, but also proximity of human ignition sources (roads and campgrounds). Associated layers of the river channel at low flow and bottomland boundaries are included for reference.

A model of natural recovery potential is presented along with component layers (overbank flow, abundance of native and non-native cover types) and assigned values, plus associated layers of bottomland boundaries, and the river channel at low flow (2010).
