HELENA – Montana Fish, Wildlife & Parks is seeking public comment on an herbicide treatment project on Nilan Reservoir.
FWP is proposes treat a 1.15-acre area within a small bay of Nilan Reservoir with the aquatic herbicide fluridone to eradicate Eurasian watermilfoil (EWM). The proposed treatment would occur Nov. 9.
EWM is a highly invasive aquatic plant; this is the first detection of EWM in this basin. Montana has limited populations of EWM so management of it is important to prevent further spread into other nearby waters. The one-time treatment will not cause any major impacts to the physical environment or human environment. The reservoir is at historic low levels so the amount of water that will need to be treated is very limited.
