Abstract
The report assesses some water quality aspects of the Columbia River and its tributaries using recent data from a one-year (11-01-71 to 10-31-72) cooperative survey. Participants in the survey included EPA, WA, DOE, OR, DEQ, USGS and some local agencies. The study was done to determine which tributaries to the main stem have the greatest adverse impact on the water quality of the Columbia River proper. The study period was divided into hydrologic quarters to differentiate between various discharge levels. Major nutrients (nitrogen and phosphorus) total coliform bacteria, temperature, pH and dissolved oxygen were measured. Sources and ambient concentrations of nitrate and orthophosphate received special attention. Although the survey yields data on many other parameters, evaluation in this report is limited primarily to the nutrient constituents.
