Perfect Duluth Day

Does anyone know why the pond at Bagley is being drained?

We walk the dog in the Bagley Nature Area at UMD daily, and since Saturday we’ve noticed the water level in the pond has been quickly dropping. It looks to be two-to-three feet lower than it was last week. There is a drain at the far end of the pond that sounds like it is open. If this is intentional, it seems like an odd time of year to be draining a pond that is home to so much wildlife.
