Lake toxins 'non-detectable'; algae results still out

TRAIL — Lost Creek Lake edged closer to seeing its public-health advisory against water contact lifted this weekend after tests this morning showed "non-detectable" levels of toxins associated with a recent blue-green algae bloom.

The U.S. Army Corps of Engineers received word of the tests for toxins associated with blooms of anabaena flos-aque, says Jim Buck, Corps Rogue River Basin project manager.

Still outstanding are results on water tested for algae volume, Buck says.

If they come in below what the World Health Organization has called unhealthy levels, it would open the door for the Oregon Department of Human Services to lift the voluntary advisory as early as Friday.

Health officials Monday issued the public-health advisory after water sampled last week at the state park's swim area showed levels of anabaena flos-aque as high as 16 times the threshold considered safe for contact.

People and pets were warned not to ingest or inhale water droplets, which could cause sickness. Also, anglers were encouraged not to eat the fish they catch there until the advisory is lifted.
