Update 4:20pm 7/26

The Nilles fire's burned acreage has been revised to around 500 acres.

Crews are now in 'hold and patrol', meaning the fire isn't necessarily contained but crews have the lines they need and are keeping an eye on things. Firefighters have also reportedly done burnouts to reduce fuel within the fire area.

No evacuation notices have been announced by the Douglas County Sheriff's Office.
