The mysterious deaths of a family of hikers from northern California and their dog have led federal officials to close 28 miles along the Merced River, where high levels of toxic algae were detected.

The Bureau of Land Management closed campgrounds and recreation areas along the river, between the towns of Briceburg and Bagby, on Friday, after receiving test results of water samples downstream from where the family died.

Algal blooms can form in waterways that are shallow and warm.

“These algal blooms can produce toxins that can make people and pets extremely sick,” Elizabeth Meyer-Shields, a BLM field manager, said in a statement.

“We will continue to monitor for the algae’s presence and look forward to when the public can safely recreate in the Merced River.”

The bodies of John Gerrish, his wife, Ellen Chung, their one-year-old daughter, Miju, and their dog were found on 17 August on a hiking trail close to the river in the Sierra National Forest. A family friend had reported them missing.

Cause of death has not been determined, and investigators are considering whether toxic algae blooms or other hazards may have contributed to the deaths.

Toxicology reports are pending. Investigators have ruled out any weapons being used or dangerous gases from a mine along the trail.

On Tuesday, forest officials had closed access to trails in the area due to “unknown hazards”.

The closure to the Merced River’s recreation areas will stay in effect until 17 September.

I don't know much about toxic algae but if a water source is contaminated and it's so severe that it kills hikers mid-stride wouldn't they find all sorts of dead animals from it? Are coyotes somehow not affected by what other canines are?

I'm assuming this is probably some type of blue algae due to how rapidly they died. We get it sometimes here in Idaho and it will literally just paralyze dogs that accidently ingest it. What kills them so fast is that paralysis also affects the lungs so unless you get them to a vet within 30 minutes, they're pretty well done for

Edit: algae name is actually Blue-green algae. Very important to note, not actually necessarily blue or green and is typically a bright color like purple, pink, or red

All the rivers are fucked out here in California. It is known in Humboldt that at least one or two dogs will die then everyone stops going to the river.
