At times, the Big O can be the best lake on the planet. In spring, for example, finding fish heavier than 10 pounds on beds is commonplace, and a 40-pound limit is not out of the question. Just ask Ish Monroe, who won an Elite Series event here in March 2012 with more than 108 pounds. However, the endless miles of vegetation on its 730 square miles can be intimidating for anglers, which is why it fell from No. 3 on this list last year. Regardless, if an angler can locate the right school of bass, they will rival limits caught on any other lake in the country.
