I can control water level if needed
Roundup QuickPRO is not labeled for use in or near bodies of water, as it is extremely toxic to aquatic life. Instead, you may consider using Hi-Yield 2, 4 - D Selective Weed Killer or Roundup Custom Aquatic Terrestrial Herbicide, which selective post-emergent liquid concentrated herbicides that controls various broadleaf weeds and other noxious plants, and targets emerged aquatic weeds in ponds, lakes, and reservoirs and lists water lily as a target weed.
