Stream fishing does not really become good until after spring runoff in May, June and July. By the end of June, summer temperatures have usually arrived, along with greater fire danger. Temperatures are often in the 90's at lower elevations, somewhat cooler in the mountains. Afternoon lightning storms are common. When fire danger conditions become extreme, open campfires may be restricted and campers will need to have self-contained stoves.
Fall brings huckleberries and hunters, and the campgrounds receive heavy use.
Both mule deer and Rocky Mountain elk are hunted along with a variety of other game. Hunting seasons and regulations are managed by the State of Oregon. Big game season usually starts in August and runs through November.
