Nutrients, Suspended Sediment, and Pesticides in Streams in the Red River of theNorth Basin, Minnesota, North Dakota, and South Dakota, 1993-95

摘要

The objectives of this report are to (1) describe nutrient, suspended-sediment,and pesticide concentration in streams, spatially and temporally during the sampling period, (2) describe loads and yields of selected constituents for selected sampling sites, and (3) identify trends in nutrient concentrations were sufficient historical data exist; and relate concentrations, loads, and yield to physiography, land use and land cover, and to possible sources and sinks. This report provides the results of sampling for nutrients, suspended sediment, and pesticides in selected streams in the Red River Basin study unit during 1993-95. During March and December 1992, samples were collected near the mouth of major streams in the study unit to determine concentrations of selected constituents during low-flow conditions.
