The lakes are open year-round. In the warmer months (early May through early October), a fee is required to use the day-use areas, which are managed by a concessionaire. Vist individual sites for details and photos.

Upper Lake Mary is the largest of Flagstaff's twin lakes. This long, narrow reservoir is especially popular with power boaters and water skiers because there is no motor size limit on it. It's also popular with those who prefer people-power or windpower over horsepower. For those who like fishing, the lake has northern pike, channel cat, crappie, and some trout.

Lower Lake Mary is the smaller of Flagstaff's twin lakes. It has a tendency to disappear during the long dry spells that periodically hit this area. When the lake has water, its banks are usually lined with anglers trying to catch the trout which the Arizona Game and Fish Department stocks here. If it stays full for a year or two, it will pick up a population of northern pike and catfish.

Picnic Areas



There are several other lakes nearby, including Marshall, Ashurst, and Mormon lakes.
