Service disruption at Willamette Mission State Park July 9-12

July 6, 2018

SALEM, Ore. – Several areas of Willamette Mission State Park will be closed to the public July 9-12 while crews work to improve visitor experience. The park entrance road will be closed for culvert work, and all day-use sites along Mission Lake and two park trails will be closed for invasive species control.

The park will remain open during this time. Visitors can access the park on foot via the 1.5 miles bike path that begins near the Wheatland Ferry parking area, off Matheny Road.

Several day-use sites and trails will be closed to visitors during the invasive species control work:
—All Mission Lake A and B day-use sites
—Mission Lake boat launch
—Entirety of Mission Trail
—Portion of Willamette Vision Education Trail that borders Mission Lake; visitors will see posted signs

Local contractors will work to replace culverts along the main park entrance road 8 a.m. to 5 p.m. on those four days. Expect heavy equipment and some noise.

Other contractors will be applying aquatic herbicides from boats in Mission Lake in the northeast section of the park. The invasive species Uruguay water-primrose (Ludwigia hexapetala) has a strong foothold in the lake and is steadily spreading. Its presence is choking out native plant and wildlife habitats, and limiting recreational use.

The aquatic herbicide spraying is a routine part of Uruguay water-primrose control. Pesticide experts from Oregon Department of Agriculture are overseeing the project.

Invasive species management at the park is a joint effort between Oregon Parks and Recreation Department (OPRD) and Willamette Riverkeeper. The project is funded by a grant from Oregon Watershed Enhancement Board.
