Crews on the White River Fire 12 miles west of Tygh Valley have increased the containment level of the 652-acre fire to 80 percent, with full containment expected by the end of the week.  Some of the 458 personnel that have been assigned to the fire were to be released today, and many will be reassigned to other fires burning in the Northwest.  Firefighters today will be working under Red Flag Warning conditions with 100-degree heat, humidity below 20 percent, and strong winds.  That increases the likelihood of increased fire activity deep inside the fire lines where there are scattered unburned fuels and numerous hot spots.  Hose lines and portable water ponds have been set up to stretch mop up capabilities deep into the White River Canyon.  Elsewhere, the Waterman Complex of fires near Mitchell has burned over 4,300 acres, and significant spread is expected today due to the hot and windy conditions.
