Description The status and trends in water quality in the Spokane River system in Washington State is mixed. Cadmium, lead, and zinc enter the system from upstream, but significant amounts of nutrients and fecal bacteria are added to the mainstem Spokane, and Hangman Creek contributes large quantities of sediment. There are preliminary indications of declining metals concentrations, and sediment in Hangman Creek has declined. Ammonia and phosphorus concentrations have been falling; other nitrogen forms, including total nitrogen, have been increasing. Fecal coliform bacteria also have been increasing, especially during the low-flow months.
