Habitat condition, both acres flooded and timing of inundation, were determined using remote sensing images from Landsat 5 and 8 for the Lower Klamath Basin, the representative basin for the southern Oregon and northeast California (SONEC) region. The dataset includes proportional water coverage (acres) for 8,825 distinct patches in Lower Klamath over 6 different time periods (1984-89; 1990-94; 1995-99; 2000-04; 2005-09; 2010-16), with a total of 368,301 acres of possibly foreageable land.

Annual export of major and trace solutes are determined for the Yukon River based on summing 42 tributary contributions. First we show that annual discharge of the Yukon River can be computed by summing calculated annual discharges from 42 tributaries using a previously published regional regression equation. Next, annual loads for 11 solutes are determined by combining annual discharge with point measurements of solute concentrations in tributary river water. Based on the sum of tributary contributions we find that the Yukon River discharges approximately 211 km super(3) yr super(-1) of water and 33 million metric tons of dissolved solids each year at Pilot Station, AK. Disch arged solutes are dominated by cations...

Wildfire is ubiquitous to interior Alaska and is the primary large-scale disturbance regime affecting thawing permafrost and ecosystem processes in boreal forests. Since surface and near surface hydrology is strongly affected by permafrost occurrence, and wildfire can consume insulating organic layers that partially control the thickness of the active layer overlying permafrost, changes in the active layer thickness following fire may mark a distinct change in surface hydrology. In this study, we examined surface area dynamics of lakes following wildfire in four regions of Interior Alaska during a 25-year period from 1984 - 2009. We compared the surface water dynamics of lakes in burned areas relative to lakes in...

The Cook Inlet Basin study unit of the U.S. Geological Survey National Water-Quality Assessment Program comprises 39,325 square miles in south-central Alaska. Data were collected at eight fixed sites to provide baseline information in areas where no development has taken place, urbanization or logging have occurred, or the effects of recreation are increasing. Collection of water-quality, biology, and physical-habitat data began in October 1998 and ended in September 2001 (water years 1999-2001). The climate for the water years in the study may be categorized as slightly cool-wet (1999), slightly warm-wet (2000), and significantly warm-dry (2001). Total precipitation was near normal during the study period, and...
