A flood warning that’s currently in effect for the Marys River will continue through Tuesday afternoon, according to the most recent National Weather Service advisory.

As of 10 a.m. Tuesday, the Marys River had leveled off at 20.55 feet. The river crested at 21.02 feet at 3 p.m. Monday as heavy rain continued to fall in the Philomath area. The NWS issued a statement that predicted the river falling below the flood stage of 20 feet in the early afternoon hours on Tuesday down to 18.6 feet. The river is then expected to remain at 18 to 19 feet Tuesday evening, levels that could remain through Thursday.

For now, significant amounts of water continue to be seen in the south end of Philomath as well as rural areas south of town. Benton County Public Works closed six roads in the vicinity, including South 13th Street, Chapel Road, Grange Hall Road, Fern Road and the section of Bellfountain Road that runs from Chapel to Airport Avenue. In addition, motorists heading to Corvallis should also be aware that Southwest 53rd Street at the railroad trestle is also closed.

Several other roads have high water signs posted, including North Creek Road in the Blodgett vicinity.

The NWS advises motorists to not attempt to drive around barricades or drive cars through flooded areas.

In Philomath, sand and sandbags continue to be available at Philomath Public Works, 1515 Willow Lane. The Public Works compound can be accessed via South 15th Street. The sand is piled in an open bay behind the building.

Philomath’s weather forecast shows a high of 45 with rain Tuesday during the day and then a low of 40 with showers continuing overnight. Rain is also in the forecast for Wednesday, Thursday and Friday with highs ranging from the mid 40s on Wednesday to low 50s on Thursday and high 40s on Friday. The weekend at this time appears as though it could be not as wet with partly cloudy conditions on Saturday and mostly sunny on Sunday with temperatures those two days in the mid 40s.

Elsewhere, the NWS also issued a flood warning for the Luckiamute River near Suver, a location that affects areas in Benton and Polk counties. The forecast reports that flooding is probable in low-lying and agricultural lands in the vicinity of Sarah Helmick State Park, Highway 99W and Parker Road. Some secondary roads and rural access roads could be flooded.

Flooding along Buena Vista Road near the confluence with the Willamette is also likely, the NPS reported, especially if the Willamette is running high.
