Wherever we traveled students took water samples to track the health of the water. Based on our continued study of the St. Louis River watershed through River Watch activities. Tests were conducted to determine dissolved oxygen, pH, nitrates, phosphates, and biochemical oxygen demand.

Miner’s Lake when it was an active mine supplied¬† WWI¬† and WWII with iron ore. Currently the pit is about 140 feet deep. Water naturally filled the hole in once the mining was done. Today it is a great fishing lake.
