It is imperative that eurasion milfoil, which can be found in many areas of northern Idaho, is not transported to Noxon and Cabinet Gorge Reservoirs. Eurasion milfoil is an aggressive invader and will have significant negative impacts to water quality, fish habitat and recreational use if established. At this time, it appears that the native aquatic vegetation is increasing. This can be attributed to several factors. Nitrogen and phosphorus levels have increased in Noxon Reservoir in recent years. This increase in nutrients fertilizes the aquatic vegetation. The longer, warmer growing seasons coupled with shorter and less intense winters also allows more vegetation growth. In ad
