It’s a beautiful March day out on Lake Tahoe, the sun is shining, the air is still and there are few other boats on the lake so the water looks like glass. The water is so pristine, it’s hard to imagine there can be anything ugly in the water. Looking into the water, schools of trout swim underneath a boat and about 50 yards away, bubbles are rising from two scuba divers below. However, when Seth Jones and Monique Rydel Fortner, co-founders of Below the Blue, surface, they are dragging with them a rusted engine block that had been used as a makeshift buoy anchor. After only a few hours on the lake, which is a short day for the two who can spend whole days diving Lake Tahoe’s shores, they pulled up 650 pounds worth of discarded items.
