Abstract
The Voluntary Nutrient Reduction Program (VNRP) for the Clark Fork River has set a target of reducing non-point source nutrient inputs by 20%. In-stream target levels are 20 ppb for total phosphorus and 300 ppb for total nitrogen. In order to assess whether this was being worked towards and to identify areas of concern, long-term monitoring was of nutrient input to the Clark Fork River and tributaries of concern was proposed in the spring of 1998. Monitoring began in the fall of 1998, and has continued to the present. In 2000, some sites on the Bitterroot River were added.
