West Mayer State Park will be closed starting Monday until mid-April to allow for a construction project that will replace the boat ramp, expand and improve vehicle parking, and replace the vault restroom.  The Oregon Parks and Recreation Department, the Department of Fish and Wildlife and the State Marine Board are partnering in the effort.  Park Manager David Spangler says the improved boat ramp will provide anglers and others better facilities to launch into the Columbia River.  The Parks and Rec Department is contributing $858,000 through its Facility Investment Program, a Fish and Wildlife Department grant of $800,000, and a Marine Board grant of $342,000 will cover the over $1.14 million project cost.  Boat anglers can alternatively access the Columbia River at the Port of The Dalles or Hood River during the construction period this winter.  Tapani Construction of Battle Ground has been awarded the project.
