LEWISTON, ID – Concerns have surfaced regarding the safety of Lewiston Orchards Irrigation District (LOID) water after a local family questioned whether it played a role in their dog’s death. According to the Idaho Animal Rescue Network, residents in the area have also reported additional pet illnesses that may be linked to cyanobacteria, also known as blue-green algae.

While current levels measure 3.5—below the common threshold of 4.0—advocates caution that this does not eliminate potential risks. Cyanobacteria can be toxic to pets and livestock, sometimes causing illness or death within hours of exposure. These blooms often appear as pea soup green scum, foam, mats, or paint-like streaks on the water.

The rescue organization recommends avoiding LOID water for drinking, swimming, or livestock use until more information is available. Residents are encouraged to check the Idaho Department of Environmental Quality website for harmful algal bloom updates and to report any suspected blooms.

Officials stress that immediate veterinary care should be sought if animals show symptoms such as vomiting, diarrhea, or seizures.
