FORT COLLINS, Colo. (AP) - The maker of Fat Tire beer says it will be monitoring the water it gets from the city of Fort Collins to check for residue from a deadly wildfire that put ash in northern Colorado's Poudre (POO'-dur) River.

The Fort Collins Coloradoan reports (http://tinyurl.com/9dygwqo ) that New Belgium Brewery's chemists have identified six compounds in the river water that could affect the flavor of its beer.

The Poudre runs through the High Park Fire burn area. The blaze destroyed more than 250 homes, killed one person and scorched 136 square miles in June.

Runoff from the burned-out slopes has turned the river black.

The city utility says it hasn't drawn any water from the river since runoff began, but it hopes to begin again next month.
