Turns out a clogged drain line at a nearby dairy sent milk overflowing into a sewer and into the creek. The line was cleared, and fire officials said in a Facebook post that there was no public health threat, but there were some puns. Here's one. I heard there was only a 2% chance of this ever happening. I didn't say good puns. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
