Due to low water levels, the boat ramps at Lyman Lake will be closed until levels rise to a safe standard. Non-motorized vessels can still be launched from our beach access points.

Annual Weather
Lyman Lake sits an elevation of approximately 6,000 feet above sea level in Apache County, Arizona. Summers are beautiful with temperatures in the mid to high 80s, sometimes low 90s, but summer evenings dip into the high 50s and low 60s at night. Winters can be cold, and snow makes an appearance once in a while which really accentuates the natural beauty of this park.
The phrase "Partly cloudy with a breeze" could be used to describe the most common type of weather experienced art this high country park. The sun makes an appearance most days, there's enough rain to keep it green, but not typically enough to ruin your trip! Unlike other parts of Arizona, all four seasons can be experienced here, and each one brings its own set of amazing features!
