资源简介：
Five lakes and their outlet streams in the Lake Tahoe Basin were sampled for
nutrients during 2002-03. The lakes and streams sampled included Upper Echo,
Lower Echo, Fallen Leaf, Spooner, and Marlette Lakes and Echo, Taylor, and
Marlette Creeks. Water samples were collected to determine seasonal and spatial
concentrations of dissolved nitrite plus nitrate, dissolved ammonia, total
Kjeldahl nitrogen, dissolved orthophosphate, total phosphorus, and total
bioreactive iron. These data will be used by Tahoe Regional Planning Agency in
revising threshold values for waters within the Lake Tahoe Basin. Standard U.S.
Geological Survey methods of sample collection and analysis were used and are
detailed herein. Data collected during this study and summary statistics are
presented in graphical and tabular form.
