This is poor herbicide application practice. When spraying using lance-application it is a requirement to leave a 1 metre un-treated buffer zone between the top of the waterway and the herbicide. This gap compensates for any drift and prevents chemicals entering the waterway.
It has also been found in a study that herbicides have a detrimental effect on certain amphibians. Moreso than funicides or insecticides (Yasuda, Koike & Terman, 2008).
