The Washoe County wildfires burning across northern Nevada have displaced thousands of residents, prompted a state of emergency, and shuttered eight schools for a second consecutive day. Investigators have now determined all three active fires were started by human activity.

The situation remains fluid, with evacuation zones expanding into new areas Monday evening.

Three Fires, Three Starting Points

Each blaze began separately over a three-day stretch.

The Bug Fire ignited around 3:30 p.m. Saturday near the California Agricultural Inspection Station at Long Valley. It is by far the largest, having consumed 16,680 acres with containment holding at just 4 percent.

The Fred Mountain Fire started around 10:45 a.m. Sunday on Fred’s Mountain in Nevada. It has burned 3,482 acres with no containment reported.

The Stallion Fire began at 8:45 a.m. Monday southwest of Pyramid Lake. It has reached 1,000 acres, also with no containment listed.

Truckee Meadows Fire Protection District spokesperson Kimberly Flores explained the naming convention, noting that each fire takes its name from a nearby geographic feature such as a street, mountain or building. The Bug Fire, for instance, references the agricultural inspection facility locally known as the bug station.

All Three Determined Human-Caused

Officials confirmed Monday that investigators have concluded all three fires resulted from human activity. No additional details were released, with authorities citing ongoing investigations.

That determination does not distinguish between accidental and intentional causes, and officials declined to elaborate further.

Schools Closed a Second Day

The Washoe County School District announced Monday night that eight campuses would remain shut Tuesday, citing continued impacts from the Bug Fire including evacuations and power outages. The decision followed consultation with fire officials.

Closed Tuesday, August 11:

• Jesse Hall Elementary School
• Spanish Springs Elementary School
• Desert Heights Elementary School
• Silver Lake Elementary School
• Lemmon Valley Elementary School
• Shaw Middle School
• Spanish Springs High School
• Alyce Taylor Elementary School

The district also confirmed it will not operate bus routes through areas designated red or yellow, meaning zones under active evacuation or evacuation watch.

State of Emergency Declared

Governor Joe Lombardo declared a state of emergency covering affected portions of Washoe County and the Reno-Sparks Indian Colony.

He noted that thousands of Nevadans have been driven from their homes as the fires continue threatening communities, and said the state was taking every available measure to support local responders, safeguard lives and property, and direct resources where they are most needed.

The declaration streamlines cross-jurisdictional cooperation, allowing agencies across the state to move personnel and equipment into northwestern Nevada more quickly. Lombardo also requested federal assistance, including National Guard personnel and equipment.

Where Evacuations Stand

Roughly 10,000 people have been evacuated across the three fires. About 4,000 have since been cleared to return to the Cold Springs area.

Monday brought further expansion. The mandatory evacuation zone covering the Bug and Fred Mountain fires grew to include the north side of Rancho Haven, while warning areas extended toward Wildcat Hill and Dry Valley Creek.

Later Monday evening, evacuation warnings were issued for portions of Nixon, located east of the Stallion Fire.

Injuries and Damage

Two injuries have been reported, one firefighter and one civilian. Both were treated and released.

Officials confirmed homes have been lost but did not provide figures or locations during Monday’s briefing.

Approximately 350 personnel are currently assigned to the firefighting effort.

Weather Is the Wild Card

Truckee Meadows Fire Protection District Chief Richard Edwards said weather remains a constant concern, with crews watching thunderstorms moving into the region.

Those storms carry conflicting implications:

• Wind can drive flames in unpredictable directions and push fire beyond established lines
• Lightning can ignite additional starts in already stressed terrain
• Rain could aid suppression efforts if it arrives in useful quantity

The uncertainty makes planning difficult. A storm system can either help crews significantly or create an entirely new set of problems within the same afternoon.

Officials at the Briefing

Lombardo appeared alongside Washoe County Sheriff Darin Balaam, Reno-Sparks Indian Colony Chair Doug Gardipe and fire officials at a Monday afternoon press conference to review the response so far.

The inclusion of tribal leadership reflects the emergency declaration’s coverage of the Reno-Sparks Indian Colony, where residents face the same threats and displacement as surrounding communities.

What Residents Should Do

For anyone in or near the affected zones, a few practical steps apply.

Check the perimeter map regularly rather than relying on secondhand information, since boundaries have shifted multiple times within single days. If you are in a warning area, pack essentials now, arrange for pets and livestock, and identify a destination before an order arrives. If you are in an order area, leave immediately.

Families with children at the eight closed schools should plan for a second day without transportation and monitor district communications for Wednesday’s status.

Where Things Stand

Three fires burning simultaneously, more than 21,000 acres consumed, containment barely established on the largest and nonexistent on the other two, and 350 personnel spread across a wide front.

The next several days will hinge substantially on what the incoming weather delivers.
