1987-1991 water years data on surface-water-quality conditions in the Yakima River Basin, Washington. The report summarizes spatial and temporal distributions of dissolved oxygen, temperature, pH, sediment, nutrients, pesticides, trace elements, bacteria, radionuclides, and aquatic ecology. The basin, covering 6,155 square miles, is divided into three distinct reaches with differing water-quality conditions influenced by geology and land use.
Use Cases
- Analyze spatial distribution of contaminants based on the three distinct river reaches described
- Assess temporal trends in water quality parameters like dissolved oxygen and temperature over the 1987-1991 period
- Model the impact of agricultural and irrigation activities on nutrient and pesticide loads mentioned in the description
- Compare water quality conditions between less-degraded headwaters and intensively farmed valleys
- Evaluate geologic sources of trace elements like arsenic and chromium from specific subbasins
Strengths
- Data covers a 5-year period (1987-1991 water years) for temporal analysis
- Report summarizes multiple water quality parameters including dissolved oxygen, nutrients, pesticides, and trace elements
- Analysis is spatially detailed, dividing the 6,155 square mile basin into three distinct reaches with different characteristics
Limitations
- Last updated 1991-11-01 23:59:59.999000; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
