As best I understand, whatever herbicide sprayed at the retention ponds cannot be used unless it is labeled for such use. Assuming that to be the case, US EPA will have approved the material for the use you saw. Now, the dead plant material decomposes and sucks oxygen out of the water and can negatively impact the flora and fauna. Good/Bad? Sort of depends on "whose ox is being gored".

While birding 2 small retention ponds this week in Jefferson Parish along Causeway Blvd. in Metairie, I came upon a company that was spraying what I guess was a herbicide on the vegetation that has grown up over most of the shallower pond on the east side of Causeway blvd . Migrating shorebirds use this area along with wading birds. There are black -necked stilts there daily . The next day I noticed several ibis feeding in this same area that had just been sprayed the day before. I am interested in how this will affect these birds, directly or indirectly . Is there a herbicide that is not toxic to wildlife?
