The annual Trout Derby at Powder Mills Park in Rochester, New York, has been rescheduled from April 4 to April 18 due to significant flooding in Irondequoit Creek. The decision was made to ensure the safety of participants, as the creek's water levels have risen to unsafe levels following recent heavy rainfall. The Trout Derby is a highly anticipated event that marks the beginning of the trout fishing season and supports the park's hatchery operations. It typically attracts over 600 anglers and is sponsored by the Riedman Foundation.
