PARK UPDATE:

Warning: Algae Bloom on Lake Cascade

– There are toxins present in the lake, but not high enough to issue a health advisory
– While there are no contact warnings currently in place, it may be harmful if ingested
That being said, Idaho Parks and Recreation would still like to strongly suggest that all lake users exercise caution, especially children, pets, and other sensitive individuals.
We will continue to keep you apprised of new information as we know it.
