Recent rains have raised Clear Lake’s level to 6.37 feet on the Rumsey Gage, nearing the official 7.56-foot “full lake” mark, creating ideal conditions for the three-day season opener, the WON Bass Winter Open, starting tomorrow and running through the weekend. Experts predict a strong chance for a “Century Belt” performance (catching over 100 pounds of bass) for competitors vying for the top $55,000 Ranger/Mercury prize.
