SALT LAKE CITY — The Pine Hollow and Silver Lake Flat reservoirs remained closed Sunday morning even though firefighters contained the Tibble Fire.

Utah Fire Info said crews reached 100% containment early Sunday, Utah Fire Info tweeted.

Helicopters will be using the closed reservoirs as landing sites so they reload for water drops until firefighters are comfortable.

The reservoirs will reopen once firefighters are comfortable with leaving the site. The Salmon Heli-Rappelers were on scene mopping up.

Forecasts predicted the area could receive additional thunderstorms Sunday. Lightning is a constant threat for igniting wildfires.

The Hibble Fire was a small one by comparison to other fires in Utah. It burned about a half acre but Utah’s severe drought has firefighters jumping on every fire so it doesn’t explode into a bigger problem.
