| Notes | "Data are presented from a study of algal and nutrient dynamics in the South Umpqua River Basin in southwestern Oregon during summer, low-flow periods from September 1990 to October 1992. The study was done to assist local and state regulatory agencies in determining total maximum daily loads of nutrients for the basin in order to maintain dissolved oxygen greater than 90 percent of saturation and pH less than 8.5 units. Fifty-one sites, including South Umpqua River, tributaries, and wastewater-treatment plant effluents, were sampled during this period." ((from the Abstract) |
