There are reports of chunks of ice floating in the north bays as of this morning. Sharon Natzel took this video of the ice beginning to move out of her bay on Sunday April 3rd. The noise you hear on the video is mainly wind.
As you can see in this link from the DNR, 2016 Ice Out Data, the ice is completely gone on most lakes in the area, but not from Long Lake. Zoom in to find Park Rapids.
