Alaska resource data file: McGrath quadrangle
Thomas K. Bundtzen
1999, Open-File Report 99-357
The unnamed occurrence was investigated by the reporter in 1978 during a 1:63,360 scale geologic mapping effort for the Alaska Division of Geological and Geophysical Surveys in the McGrath quadrangle (Bundtzen and Laird, 1983). Two grab samples from the mineralized zone contained up to 222 ppm copper, 0.6 grams/tonne silver,...
Spatial distribution of chemical constituents in the Kuskokwim River, Alaska
Bronwen Wang
1999, Water-Resources Investigations Report 99-4177
The effects of lithologic changes on the water quality of the Kuskokwim River, Alaska, were evaluated by the U.S. Geological Survey in June 1997. Water, suspended sediments, and bed sediments were sampled from the Kusko-kwim River and from three tributaries, the Holitna River, Red Devil Creek, and Crooked Creek. Dissolved...
Perennial snow and ice volumes on Iliamna Volcano, Alaska, estimated with ice radar and volume modeling
Dennis C. Trabant
1999, Water-Resources Investigations Report 99-4176
The volume of four of the largest glaciers on Iliamna Volcano was estimated using the volume model developed for evaluating glacier volumes on Redoubt Volcano. The volume model is controlled by simulated valley cross sections that are constructed by fitting third-order polynomials to the shape of the valley walls exposed...
Water-quality assessment of the Cook Inlet Basin, Alaska — Environmental setting
Timothy P. Brabets, Gordon L. Nelson, Joseph M. Dorava, Alexander M. Milner
1999, Water-Resources Investigations Report 99-4025
The Cook Inlet Basin in Alaska is one of 59 study units selected for study for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment program. The Cook Inlet Basin study unit encompasses the fresh surface and ground waters in the 39,325 square-mile area that drains to...
Effectiveness of streambank-stabilization techniques along the Kenai River, Alaska
Joseph M. Dorava
1999, Water-Resources Investigations Report 99-4156
The Kenai River in southcentral Alaska is the State's most popular sport fishery and an economically important salmon river that generates as much as $70 million annually. Boatwake-induced streambank erosion and the associated damage to riparian and riverine habitat present a potential threat to this fishery. Bank-stabilization techniques commonly in...
Hydrology, geomorphology, and flood profiles of the Mendenhall River, Juneau, Alaska
Edward G. Neal, Randy H. Host
1999, Water-Resources Investigations Report 99-4150
Water-surface-profile elevations for the 2-, 20-, 25-, 50-, and 100-year floods were computed for the Mendenhall River near Juneau, Alaska, using the U.S. Army Corps of Engineers Hydrologic Engineering Center River Analysis System model. The peak discharges for the selected recurrence intervals were determined using the standard log-Pearson type III...
Water-quality assessment of the Cook Inlet Basin, Alaska — Summary of data through 1997
Roy L. Glass
1999, Water-Resources Investigations Report 99-4116
Among the first activities undertaken in each National Water-Quality Assessment (NAWQA) investigation are the compilation, screening, and statistical summary of available data concerning water-quality conditions in the study unit. The water-quality conditions of interest are those that are representative of the general ambient water quality of a given stream reach...
Precipitation-runoff, suspended-sediment, and flood-frequency characteristics for urbanized areas of Elmendorf Air Force Base, Alaska
Timothy P. Brabets
1999, Water-Resources Investigations Report 98-4265
The developed part of Elmendorf Air Force Base near Anchorage, Alaska, consists of two basins with drainage areas of 4.0 and 0.64 square miles, respectively. Runoff and suspended-sediment data were collected from August 1996 to March 1998 to gain a basic understanding of the surface-water hydrology of these areas and...
Characteristics of the Alaskan 1-Km Advanced Very High Resolution Radiometer data sets used for analysis of vegetation biophysical properties
Carl J. Markon
1999, Open-File Report 99-401
In this study, data characteristics for composited, multitemporal Advanced Very High Resolution Radiometer data sets for Alaska were assessed for a 7- year period from 1991 to 1997. This involved consideration of the satellite sensors used, data processing performed, and data set compilation, along with an analysis of acquisition date,...
Sustainable fisheries management: Pacific salmon
E. Eric Knudsen, Cleveland R. Steward, Donald MacDonald, Jack E. Williams, Dudley W. Reiser, editor(s)
1999, Book
What has happened to the salmon resource in the Pacific Northwest? Who is responsible and what can be done to reverse the decline in salmon populations? The responsibly falls on everyone involved - fishermen, resource managers and concerned citizens alike - to take the steps necessary to ensure that salmon...
Concentrations of fecal coliform bacteria in creeks, Anchorage, Alaska, August and September 1998
Joseph M. Dorava, Andra Love
1999, Open-File Report 99-236
Water samples were collected from five creeks in undeveloped, semi-developed, and developed areas of Anchorage, Alaska, during August and September 1998 to determine concentrations of fecal coliform bacteria. In undeveloped areas of Ship, Chester, and Campbell Creeks, and the semi-developed area of Rabbit Creek, concentrations of fecal coliform bacteria ranged...
Geochemical data for stream-sediment, heavy-mineral-concentrate, and rock samples collected from the Fortyseven Creek gold-arsenic-antimony-tungsten prospect, southwestern Alaska
John E. Gray, G. K. Lee, R. M. O’Leary, P. M. Theodorakos
1999, Open-File Report 99-584
In the summer of 1991, we conducted a reconnaissance geochemical survey around the Fortyseven Creek Au-As-Sb-W prospect that is located in the southwestern part of the Sleetmute quadrangle. At that time, this project was a small part of a more comprehensive Alaska Mineral Resource Assessment Program (AMRAP) study of the...
