ODF report, July 26th, 11:46 a.m. – Location: 28 miles northeast of Klamath Falls, OR; Size: 409,611 acres; Personnel: 2,257; Containment: 53%. Klamath Falls, ORE. – As firefighters successfully patrol and hold the containment line around the southern area of the Bootleg Fire, activity continues on the northern edges. Along the northwest perimeter of the fire, crews have been building indirect line utilizing forest roads from Coyote Creek, north to Round Butte. A burnout operation was conducted overnight to remove fuels ahead of the fire to stop its spread into timber stands. “The challenge Monday,” said Pacific Northwest Team 2 Operations Chief Kyle Cannon, “is to secure the northernmost section of the fire north of Round Butte to the west side of 27 Road.” On the northeast side, Sunday night’s efforts focused again on the active fire along the Sycan River. Crews there are working to keep the fire off Winter Rim and from moving toward Summer Lake. Contingency line construction and structure protection continue around Summer Lake and Paisley. Incident managers are optimistic about the effectiveness of these efforts, but threats remain and evacuation levels have not yet changed. They encourage people to remain vigilant and updated on conditions. Along the southern border, crews continue to progress deeper into the burned area extinguishing hot spots. This will further secure the fire’s edge. Firefighters have made excellent progress, with 98 miles of completed fire line in this zone. As they continue to patrol, any areas of remaining heat that could pose a future threat to the containment line will be extinguished.  Over the course of the fire, more than 90 fire departments from across the country have responded to the fire to serve the impacted communities. Monday, an additional 120 Oregon National Guardsmen are arriving—six crews of 20—to join the firefighting force. Weather and smoke conditions are improving over the next few days. Sunday night’s light, favorable winds from the north facilitated night operations. Although rainfall is rare this time of year, Monday thunderstorms are expected to roll in and produce rain Monday night and Tuesday. While there is a danger of lightning, the rainfall, higher humidity, and cooler temperatures overall will assist firefighting efforts. Air quality has also eased across the state with most monitoring stations recording good to moderate air quality.
