Stone Creek Golf Club will be hosting its first OGA Championship since the 2009 OGA Tournament of Champions. However, the course has hosted yearly Oregon Amateur qualifiers for a number of years the past decade. In last year's Oregon Mid-Amateur Championship, held at Arrowhead Golf Club in Molalla, Lara Tennant (Portland, Ore.) won the second of her two OGA Championship wins in 2017, while former Oregon Amateur winner Jack Dukeminier (Beaverton, Ore.) used a strong Sunday finish to win an OGA title for the second-consecutive year.
After taking place separately in 2017, this year's Oregon Women's Stroke Play and Oregon Super Senior Championships will once again be held concurrently in 2018, this time at Broken Top Club in Bend, Ore. The private club located on the west side of Bend last hosted the 2010 OGA Men's Team Championship. In last year's Women's Stroke Play, Haleigh Krause (Eugene, Ore.), who plays collegiately at San Diego State University, won by an astounding six shots at Rose City Golf Club in Portland. The 2017 Oregon Super Senior was held at the Ghost Creek course at Pumpkin Ridge in North Plains, won by Sam Spicher (Beaverton, Ore.).
This year's Oregon Net Championship will take place at The Courses at Resort at the Mountain, located on the west side of Mt. Hood in Welches, Ore. The facility hosted the Inaugural Women's Interclub Play Championship in 2014, and also hosted the 2006 Oregon Women's Best-Ball. The Net Championship, held in 2017 at the OGA Golf Course, was won by Scot Canter (Milwaukie, Ore.) and Rita Hamann (Albany, Ore.).
