Algae Bloom Prompts Water Advisory at Nearby Lake
Ferdinand, ID · October 9, 2026
Friday night football returns under the stadium lights tonight, but anyone eyeing a weekend fishing trip will want to adjust their plans first.
The Lead
A routine water quality screening has triggered a public health advisory at Winchester Lake, warning Camas Prairie visitors to avoid contact with the reservoir heading into the weekend. Testing conducted by the Nez Perce Tribe Water Resources Division alongside state environmental officials confirmed elevated levels of toxin-producing cyanobacteria, commonly known as blue-green algae.
The advisory, issued by the Idaho Department of Health and Welfare, urges people, pets, and livestock to stay clear of the shoreline water. Swallowing or wading through blooms can trigger rashes, nausea, and respiratory distress, and standard boiling or camping filtration does not neutralize the toxins. Anglers may still keep their catch provided the fish are rinsed with clean domestic water and prepared strictly as trimmed fillets. Winchester Lake State Park remains open for camping and hiking, with environmental technicians scheduled to run weekly follow-up water tests until cell counts normalize.

Spotlight & Story
