Ahh, a quarry/gravel pit. That usually means less productive water, which doesn't equal big or at least monstrous bluegills. Thus, we will see the Condello initiative up and rolling again. Will it be feeding, will it be fertlization, will it be other???? Can he really let this one take its course without active management?
Meanwhile, what a gorgeous resource with that wonderful water quality. It will be a pleasure for you to sit on the porch in the evening and see that site, Dr. Bruce!
