Survey of Lake Ontario bottom sediment off Rochester, New York, to define the extent of jettisoned World War II matériel and its potential for sediment contamination
Gregory Kennedy, William M. Kappel
2000, Open-File Report 99-237
Military-type matériel was recovered from the bottom of Lake Ontario near Rochester, N.Y., during bottom-trawl, fish-stock surveys at depths of 75 to 180 feet each year from 1978 through 1996. The recovered matériel included many shell-detonator nose cones (2 inches in diameter by about 3.5 inches long); several electronic components;...
Water quality modeling in the systems impact assessment model for the Klamath River basin - Keno, Oregon to Seiad Valley, California
R. Blair Hanna, Sharon G. Campbell
2000, Open-File Report 99-113
This report describes the water quality model developed for the Klamath River System Impact Assessment Model (SIAM).

Stable hydrogen and oxygen isotope ratios for selected sites of the National Oceanic and Atmospheric Administration's Atmospheric Integrated Research Monitoring Network (AIRMoN)
Tyler B. Coplen, Richard Huang
2000, Open-File Report 2000-279
Increasingly, hydrologic studies require information on the isotopic composition of natural waters. This report presents stable hydrogen (δ2H) and oxygen isotope ratios (δ180) of precipitation samples from seven selected sites of the National Oceanic and Atmospheric Administration's Atmospheric Integrated Research Monitoring Network (AIRMoN) collected during the years 1992-1994....
Summary of suspended-solids concentration data, San Francisco Bay, California, water year 1998
Paul A. Buchanan, Catherine A. Ruhl
2000, Open-File Report 2000-88
Suspended-solids concentration data were collected in San Francisco Bay during water year 1998 (October 1, 1997?September 30, 1998). Optical backscatterance sensors and water samples were used to monitor suspended solids at two sites in Suisun Bay, three sites in Central San Francisco Bay, and three sites in South San Francisco...

Hydrologic, Water-Quality, Sediment Transport, and Bulk Atmospheric-Deposition Data, Guanella Pass Area, Colorado, October 1, 1994, through September 30, 1997
Michael R. Stevens
2000, Open-File Report 2000-82
The hydrology and water quality of streams and lakes in the Guanella Pass area could be affected by the proposed reconstruction of the existing road over Guanella Pass between Georgetown and Grant, Colo. Data were collected during water years 1995 through 1997 (October 1, 1994, through September 30, 1997) that...
Elk-effects vegetation monitoring program for Tomales Point Elk Range, Point Reyes National Seashore, California
Kathryn McEachern, Marcia Semenoff-Irving, Pamela van der Leeden
2000, Open-File Report 2000-487
The monitoring program for elk effects on Tomales Point vegetation is designed to provide information on how tule elk grazing affects plant communities and rare species. The basic objective of the program is to show whether the elk are driving the vegetation into an unacceptable state by their grazing. The...
