To date, our team and our crew of dedicated citizen scientists have collected over 900 water quality measurements each year from the program’s 13 monitoring stations on Lake Pend Oreille and the Pend Oreille River.
Each station is evaluated for 11 different biological, chemical, and physical tests once per month from May through September. Data is collected for the following parameters: Water Temperature, Dissolved Oxygen, pH, Transparency & Turbidity, Total Kjeldahl Nitrogen, Nitrate-Nitrite, Total Phosphorus, Orthophosphate, Total Organic Carbon, Total Coliform Bacteria, and E. coli.
Taking these measurements on a regular basis helps us understand local waterways and the overall health of our lake and river systems.
