The Eagle fire covers 1,186 acres and is located about 5 miles northwest of the Bavarian-themed village of Leavenworth.
Fire spokeswoman Robin DeMario said Thursday that about 30 homes remain under mandatory evacuation notices.
She says the fire has not burned any homes.
Fire crews used helicopters to drop water on the fire on Wednesday and made progress in containing the blaze.
DeMario says the hot and dry conditions forecast for Thursday could produce an increase in fire activity.
