After a long days hike, Andy and I arrived at Courville Lake. This lake sits at almost 7000′ ft. in elevation and is at the head end of the drainage. All water recharge is a result of direct snowmelt, and by this time of year water levels are completely dependent on groundwater recharge. Upon arriving at Courville Lake we collected water samples and fish samples for ion, metal, and mercury analyses. Collection of water samples is done from an air mattress at the deepest part of the lake and then filtered. After filtering, the water is put into a cooler and then a freezer awaiting analyses at the Flathead Biological Station and the University of Montana.
