The Fisheries & Oceans Canada, in partnership with the Great Lakes Fishery Commission, plans to conduct a sea lamprey control treatment on the Salmon River (Lewis/Oswego County), Grindstone Creek (Oswego County), Little Sandy Creek (Oswego County), Black River (Jefferson County).

These treatments will be from May to June for (Salmon River, Grindstone Creek & Little Sandy Creek. August to September for (Black River, Little River & Fish Creek).

During the treatment, you may notice sea lamprey control field crews working along the stream or see temporary red or green coloration in the water. The colors come from non-toxic dyes used to monitor stream water flow so that precise concentrations of lampricides can be achieved during treatment. The lampricide treatment itself will tint the water slightly yellow, will flush from the system once the treatment ends, and dilutes & degrades to non-detectable levels shortly after the treatment ends.

As a precaution, agricultural irrigation from the treated sections of the stream should be suspended at the start of the treatment until24 hours after it concludes, & anyone holding bait fish or other aquatic organisms in stream water should use an alternate water source during this time.
