PHYSICAL AND CHEMICAL WATER QUALITY OF THE SPOKANE RIVER OUTLET REACH OF LAKE COEUR D'ALENE, KOOTENAI COUNTY, IDAHO. 1990 AND 1991
Description:
The University of Idaho conducted a water quality study on the Spokane River outlet arm of Lake Coeur dAlene (17010305, 17010303) from June 1990 through September 1991. Objectives of the study were: to characterize baseline river water quality; to determine seasonal river water quality variation, with an emphasis on thermally stratified conditions; to assess diel temperature and dissolved oxygen changes for indications of aquatic ecosystem stress; and to determine the effects of existing and proposed wastewater discharges on river water quality. Parameters measured were: in situ temperature, dissolved oxygen, and specific conductance; pH and turbidity; chlorophyll, bacteria, BOD, ammonia, nitrite, nitrate, Kjeldahl nitrogen, total phosphorus, orthophosphate, and secchi depth. A diel study was also undertaken to assess 24-hour temperature and dissolved oxygen changes above Post Falls Dam.. Falter, C.M., B. Riggers, and J.W. Carlson. 1991.
