Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023

In July 2023, the U.S. Geological Survey Alaska Science Center (USGS ASC) and the USGS Idaho Water Science Center (IDWSC), in cooperation with Alaska Department of Transportation and Public Facilities (AKDOT & PF), completed bathymetric and topographic surveys at four highway bridge structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR). The National Bridge Inventory structure number 524 on the Tanana River near Big Delta, AK is located on Alaska State Route 2 (commonly referred to as the Richardson Highway). Structure number 201 on the Tanana River near Nenana, AK is located on Alaska State Route 3 (commonly referred to as the Parks Highway). Structure number 254 on the Susitna...

Modeled and measured greenhouse gas emissions from Lake Powell and bathymetric analysis of tributary littoral habitat at different water levels

This data release contains model inputs used to estimate surface water greenhouse gas fluxes from two large arid reservoirs, Lake Powell and Lake Mead. The release also contains empirical, spatially explicit water quality and greenhouse gas data from a single field survey conducted in Lake Powell in July of 2017. Finally, this release contains surface area estimates of shallow (< 15m) tributary regions of Lake Powell under different water level scenarios.
