Water Quality Studies

In addition to collecting water quality data, Northern Water conducts nutrient loading, dissolved oxygen levels and water clarity studies. Technical committees and stakeholders define the studies’ objectives. The Nutrient Project includes the Three Lakes Nutrient Study and the Horsetooth Water Quality Study. The Grand Lake Clarity Project began three years after the Nutrient Project to evaluate water clarity in Grand Lake.
