Mercury-contaminated sediments in the North Bay: A legacy of the Gold Rush
Bruce E. Jaffe
2001, Northern California Geological Survey Newsletter (June 2001) 1-2
A legacy of the Gold Rush is mercury-contaminated sediments in the Bay. Miners used mercury to extract gold from tailings during the gold rush. A large amount of this mercury (some estimates are as great as 10,000 tons) was lost during extraction to the watershed during the gold rush era....
California's Yolo Bypass: Evidence that flood control can be compatible with fisheries, wetlands, wildlife, and agriculture
T. Sommer, B. Harrell, M. Nobriga, R. Brown, P.B. Moyle, W. Kimmerer, Laurence E. Schemel
2001, Fisheries (25) 6-16
Unlike conventional flood control systems that frequently isolate rivers from ecologically-essential floodplain habitat, California's Yolo Bypass has been engineered to allow Sacramento Valley floodwaters to inundate a broad floodplain. From a flood control standpoint, the 24,000 ha leveed floodplain has been exceptionally successful based on its ability to convey up...
Estimating evapotranspiration in natural and constructed wetlands
R. Brandon Lott, Randall J. Hunt
2001, Wetlands (21) 614-628
Difficulties in accurately calculating evapotranspiration (ET) in wetlands can lead to inaccurate water balances—information important for many compensatory mitigation projects. Simple meteorological methods or off-site ET data often are used to estimate ET, but these approaches do not include potentially important site-specific factors such as plant community, root-zone water levels,...

Survival and immobilizing moose with carfentanil and xylazine
Thomas J. Roffe, K. Coffin, Joel Berger
2001, Wildlife Society Bulletin (29) 1140-1146
The use of carfentanil with other drugs to immobilize moose (Alces alces) has yielded mixed results. Previous work on chemically immobilizing moose with these drugs reported mortality of 6–19%. Even the most recent study of free-ranging moose using the same drug combination as we used in this report (carfentanil and...
Summer habitat use by Columbia River redband trout in the Kootenai River drainage, Montana
Clint C. Muhlfeld, David H. Bennett
2001, North American Journal of Fisheries Management (21) 223-235
The reported decline in the abundance, distribution, and genetic diversity of Columbia River redband trout Oncorhynchus mykiss gairdneri (a rainbow trout subspecies) has prompted fisheries managers to investigate their habitat requirements, identify critical habitat, and develop effective conservation and recovery programs. We analyzed the microhabitat, mesohabitat, and macrohabitat use and...

2001, Conference Paper, Proceedings of the Seventh Federal Interagency Sedimentation Conference, March 25 to 29, 2001, Reno, Nevada
A newly refined technique for continuously and automatically sensing the density of a water-sediment mixture is being tested at a U.S. Geological Survey streamflow-gaging station in Puerto Rico. Originally developed to measure crude oil density, the double bubbler instrument measures fluid density by means of pressure transducers at two elevations...
GCLAS: a graphical constituent loading analysis system

2001, Conference Paper, Proceedings of the Seventh Federal Interagency Sedimentation Conference, March 25 to 29, 2001, Reno, Nevada
The U. S. Geological Survey has developed a program called GCLAS (Graphical Constituent Loading Analysis System) to aid in the computation of daily constituent loads transported in stream flow. Due to the relative paucity with which most water-quality data are collected, computation of daily constituent loads is moderately to highly...
