There, the men were questioned, Lieutenant Washburn said. “One of them started to kind of acknowledge that yeah, the fish maybe hadn’t come from Lake Powell. An otolith, Lieutenant Washburn said, has a high concentration of calcium and is sensitive to any changes in the chemistry of the water. The wildlife agency eventually learned that the men had been fishing at Quail Creek Reservoir, about 180 miles west, just before the Lake Powell tournament. “It took so long to charge the men in this case because an amazing amount of scientific work went into proving the violation,” Lieutenant Washburn said.
