Mandatory evacuations have been ordered for an area bordered by Carter Lake Reservoir to the west, Homer and Windemere roads to the north, Dry Creek Reservoir to the south and North County Road 23 to the east, according to emergency responders.

Mandatory evacuations were issued Monday afternoon for a fast-moving wildfire west of Berthoud, near County Road 8E. A red flag warning for critical fire danger was in effect statewide. A voluntary evacuation notice was also issued for areas around Lonetree and Welch Reservoirs.

Residents north of Dry Creek Reservoir were able to return to their homes after firefighters contained a "fast-moving" grass fire a little more than two hours after it ignited west of Berthoud.
