| Comments | Spotted by VLMP on Sept. 29, 2017. Public works has deployed staff to gather and dispose of (in sealed trash bags) as much water lettuce as they can from Goose Lake and two smaller downstream impoundments today in hopes of preventing its spread to the Fox River. Likely escaped from upstream pond. |
