LLOVELAND, Colo. — What looked like a typical summer afternoon at Boyd Lake State Park quickly told a different story. Boats were still on the water, families were enjoying the sunshine, and the parking lot remained busy. But a walk to the main boat ramp revealed just how much the lake has shrunk. Colorado Parks and Wildlife says the water level has dropped about 20 to 25 feet, exposing shoreline that is normally underwater. Along the way, broken cell phones were visible beneath the lake.
