Boaters watch a Great Blue Heron (Ardea herodias) fishing next to a sand bar exposed by low water on the Cedar River, Black Hawk County, Iowa. Photo taken September 26, 2006. The sandbar is exposed owing to below-average rainfall during the preceding July and August, evidenced by weeds on the sand. Some weeds are in water, suggesting that above average rains in September have already occurred, raising the water level slightly. Photo Credit: Lee S. PotterComplete Edition
