The Delta Fire continues to spread, but aggressive firefighting has strengthened lines around the perimeter. On Thursday afternoon a 20 acre flare-up between Sims and Gibson near Interstate 5 prompted officials to close the freeway in both directions, but it was reopened at around 6 O’clock Thursday night after numerous helicopter water drops doused the area. The Delta Fire has burned just over 60,000 acres as of Friday morning, with 28% containment. More firelines were built Thursday around the northern, western and southern edges. The eastern edge butts up against the fully-contained Hirz Fire, which burned 46,000 acres. 17 residential structures have been destroyed in the Delta Fire. It started a week and a half ago 2 miles north of Lakehead, while the Hirz was sparked August 9th off Gilman Road. 3300 people are working the Delta Fire. Evacuations have been lifted for Delta Road, Lamoine Road, Delta School Road, Slate Creek Road, Eagle’s Roost, Eviesbrood, Coyote Pass and the Pollard Flat Area. Other areas between Vollmers and Gibson are still evacuated. Trinity County has closed East Fork Road to Ramshorn Road east to the Shasta County line. In Siskiyou County an evacuation warning remains for Dunsmuir. Shasta County does not issue pre-evacuation warnings.
