Upon Arrival

  • Welcome to Our Resort!

    Todd and Margie Barker, Owners

    Happy greetings from myself and staff here at O'Sullivan Sportsman Resort. We get our name from the surrounding Lake 'The Potholes Reservoir' which is part of the Columbia Basin Project and formed by O'Sullivan Dam. Potholes refers to the many glacial depressions in ancient sand dunes here. These potholes and small islands make this area one of the best in Washington for recreation! There is so much to do here both on and off season and we are ready to accommodate your needs upon arrival.
