The fire near Lee Falls in Washington County has been 25 percent contained, officials said Sunday.

The fire, west of Henry Hagg Lake near Cherry Grove, started Thursday and is estimated to have burned about 290 acres of land. The cause is still under investigation.

More than 175 people, including Oregon Department of Forestry employees, contract firefighters and teams of incarcerated adults from the Coffee Creek Correctional Facility, worked Saturday to clear the fire line.

By Sunday morning, the fire was 100% out and officials said they were confident the fire would stay within its current scope. As a result, the Washington County Sheriff’s Office reduced all Level 3 (leave immediately) evacuations to Level 2 (be ready).

However, authorities are urging residents returning to their homes to remain vigilant and prepare for future evacuations if the fire situation changes significantly.

“Good coordination between wildland firefighting resources, structural firefighting agencies and the Washington County Sheriff’s Office ensured the safety of the Cherry Grove community during this incident,” Lee Falls Fire Chief Neal Bond said in a news release.

Ground crews and a helicopter will continue to work over the next few days to better contain the fire and return firefighting responsibility to the local Forest Grove District. Henry Hagg Lake will remain closed Sunday so aerial firefighters can continue to have access to fight the blaze, said Washington County Sheriff’s Deputy Kendall Hazel. Hazel, who also serves as public information officer, said continued use of the lake by aerial firefighters will be reviewed Sunday evening.
