OROGRANDE – The community of Orogrande remains under a “Level 3-GO” evacuation notice, issued by the Idaho County Sheriff’s Office.
Crews were able to remove trees that had fallen over the 233 and 311 Roads, but numerous standing dead trees (“snags”) remain a dangerous hazard. For this reason, the roads into Orogrande remain closed. Heavy equipment will be utilized to help open up roads, given the numerous trees that have fallen. Due to an inversion and poor visibility, aerial resources were unable to assist ground crews yesterday. Crews identified and mapped structures in the Red River Valley and will assess structure protection needs, should the fire progress toward that area.
Engines previously on the night shift will transition to the day shift, along with additional engines expected to arrive today. Resources will continue to engage the fire in Orogrande and the Crooked River corridor, extinguishing hot spots. Aerial resources will be available to assist crews today, weather permitting.
An overnight infrared flight mapped the fire at 12,956 acres.
TWIN LAKES FIRE (east of Twin Lakes and Hagen Creek)
Start Date: 8/25/2022 Cause: Lightning Size: 950 acres * Completion: 19 %
Total Personnel: 9 Wildfire Fire Module: 1
A structure protection module is implementing structure protection measures at Moore’s Station. Firefighters have completed structure protection measures at Square Mountain Lookout. An overnight infrared flight mapped the fire at 950 acres.
WEATHER AND FIRE BEHAVIOR
On the Williams Creek Fire, interior unburned islands of fuel will continue to grow together and fill in the perimeter. While these pockets of intense heat continue to burn and fill in along the eastern flank of the fire, existing roads, timber harvest units and a previous fire footprint are helping to limit and slow the fire spread beyond its current perimeter. On the Twin Lakes Fire, the northern flank was somewhat active until the smoke from adjacent fires tamped down heat and venting.
Temperatures are expected to increase about five degrees (high 80s) with relative humidity levels in the low teens in both fire areas. Winds will be light but could gust up to 12 mph. Showers are likely later in the week, with a slight possibility of rain starting Tuesday. Poor overnight humidity recoveries will lead to an increase in fire behavior earlier in the morning. The fire’s activity will be terrain driven, where fuels and slope align. Perimeter growth is unlikely; however, the north side of the Williams Creek Fire may see a slight increase in the Six Mile area with the fire backing upslope. Low relative humidity and high temperatures will increase the risk of any sparks creating new fire starts.
CLOSURES AND SPECIAL MESSAGES
Closures surrounding both fire areas are necessary to protect the safety and welfare of the public and provide for safe firefighting efforts and access. An updated closure for the Williams Creek fire area is forthcoming, given the fire movement and progression earlier this week. Additional roads and trail will be closed for public safety.

* “Percent completion” of objectives more accurately captures and reports the specific amount of work accomplished on the ground to manage fire spread and reduce the negative impacts to communities, infrastructure, and other identified values.
By using percent completion of objectives, fire managers can illustrate how they are progressing with the accomplishment of objectives that have been identified and prioritized.
As a comparison, “containment” implies firelines around the entire perimeter, directly next to the fire’s
