| Short Description |
A study was conducted by the Washington State Department of Ecology to address water quality concerns of the Pend Oreille River between Albeni Falls and Box Canyon Dams. Five stations were sampled every three weeks between July and November 1988. Water quality was generally good and well below the threshold of eutrophication conditions.

| Abstract | Long Description |
A study was conducted by the Washington State Department of Ecology to address water quality concerns of the Pend Oreille River between Albeni Falls and Box Canyon Dams. Five stations were sampled every three weeks between July and November 1988. Water quality was generally good, and well below the threshold of eutrophication conditions. Phytoplankton species were typical of oligotrophic to mesotrophic waters. Periphyton concentrations were well below nuisance levels for aesthetic impairment. Macrophytes were responsible for water quality violations for pH and total dissolved gases during the peak of the growing season. There was no significant difference between sample stations for nutrients, suggesting macrophyte occurrence and sediments do not elevate instream nutrient loads. Brackett Creek, Skookum Creek, and South Fork Lost Creek exceeded Class A water quality standards for fecal coliform. |
