HERRIMAN — Crews were fighting a grass fire Saturday approximately 1 mile south of the Juniper Point area, according to city officials.

The grass fire started shortly before noon, officials said. Area residents reported seeing smoke from their homes, but few other details were immediately available. Herriman spokeswoman Tami Moody said the fire was about two football fields in size.

Authorities closed access to Black Ridge Reservoir because helicopters are using it to fill water buckets to fight the fire. No homes or structures were threatened.

Fire crews were keeping abreast of wind conditions, Moody said, noting the wind was blowing in a northwest direction.

"We are definitely trying to be as proactive as possible in hopes to avoid something along the lines of the Machine Gun Fire or the Rose Crest Fire," she said.

The Rose Crest fire in 2012 burned more than 600 acres, while the Machine Gun Fire burned three homes and some outbuildings in 2010.
