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...

These layers show the relative abundance of native, non-native and tree cover types as mapped for the Colorado River Conservation Planning Project. Relative abundance (Dominant, Common, Mapped by Sparse and Not Mapped) is determined by the listing of cover types per patch.
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.

This map shows average seasonal minimum and maximum flow rates at major gaging stations. The period of record varies for each gaging station; averages were for the entire period of record up to 9/30/2010.

This collection of maps shows relative habitat quality for a suite of species that use riparian overstory habitats. Component layers include: tree patch size, presence and complexity of riparian understory, and abundance of tamarisk. Associated layers such as river channels at high flow and bottomland reaches are included for reference.

This collection of maps shows fluvial geomorphic features of the Colorado River bottomland including river channel boundaries at high flow (31,300 cubic ft/sec on 06/28/2011 at the Cisco gage) and at lower flow (3,410 cubic ft/sec on 09/06/2010 at the Cisco gage). Also shown is the bottomland boundary delineating the currently active fluvial surface; the bottomland is subdivided by both reaches and bottomland kilometers for reference. Centerlines for the bottomland and 2010 river channel are included, also.
This set of maps shows relative habitat quality for species that prefer open areas. Component layers (herbacoeus areas, distance to high water) are included, as are associated layers of channel boundaries, reaches, and bottomland kilometers.
These layers show some of the human interactions with the bottomland area. Recreation sites, roads, fuel treatment areas, and river camp layers were all acquired from project partners or publically available data and clipped to or near the bottomland boundary for use here. Bottomland reaches, kilometers, 2010 channel layers were created for the Colorado River Conservation Planning project.

This collection of maps shows vegetation cover types that are either Dominant or Common (see project documentation for full methodology in mapping). Sparse cover types are not shown here. All patches have a dominant cover type, but not all have a Common type. Vegetation features were mapped by National Park Service staff; ground-truthing and editing of vegetation data was done by project staff, as was mapping of bare areas and channel features. Associated layers of river channels, reaches, and bottomland kilometers are included for reference.
This set of maps shows relative habitat quality for bat watering. Component layers (distance to water, vegetation cover types, open flight areas) are included, as are complementary layers of channel boundaries, reaches, and bottomland kilometers.
This map shows the potential current distribution of Colorado River Cutthroat Trout as well as current and near-term status, and long term potential for change (due to climate change).
