Many of the streams and creeks that flow into the Snake River in Jackson Hole have demonstrated elevated levels of algae that are well above what would be considered healthy for this area. Elevated algae levels can negatively impact fish habitat and human health. While we are not at crisis levels yet we want to solve this well before we get anywhere close. A prime cause of the algae is directly related to excess levels of nutrients entering the surface and ground water. It has been determined that one of the largest sources of this nutrient pollution comes from excessive residential lawn fertilizer applications.
