Whitewater Preserve is a nature preserve owned and managed by The Wildlands Conservancy, a nonprofit land conservancy. Consisting of 2851acres of land in Riverside County, California, the preserve features the perennial Whitewater River flowing through a desert canyon. The preserve is located within the San Bernardino Mountains and is part of the Sand to Snow National Monument. More preserves can be found in the list of preserves.
The preserve has hiking trails, picnic areas, a restroom, a walk-in campground, a wading pool, and a Ranger Station Visitor Center. Individual picnic tables are distributed around a wooded area and meadow. A Ramada has a group picnic area.
Canyon View Loop trail crosses the river and intersects with the Pacific Crest Trail, climbing a ridge with views into the canyon and then returning to the start. Alternatively, hikers can continue further south or north on the PCT. Heading north on the PCT, destinations include Red Dome, the Mission Creek Trail junction, and the San Gorgonio Overlook. Red Dome is a pockmarked rock and is one of the few shade spots along the trail. The overlook provides a view of Whitewater Canyon and San Gorgonio Mountain. An option is to head down Mission Creek Trail to the Mission Creek Preserve Stone House campground.
Guided nature walks are offered. An interpretive program for kids focuses on desert water cycles and watershed ecology.[1] [2]
The preserve has a small wading pool that people can use. Downstream from the preserve, the stream passes through BLM property. BLM closes land along the river during fire season. People access the river despite the closure, and there are conflicts between river recreationists and local landowners. The problem is further complicated in that the preserve has limited parking and can't accommodate everyone who wants access to water.[3] The preserve closes when heavy rains are predicted due to potential flash floods.[4]
The Visitor Center is at an altitude of 2,223 feet. The Whitewater River flows year-round from San Gorgonio Mountain down a canyon into the desert, eventually reaching the Salton Sea. The preserve is located in an ecotone where the Mojave Desert and Sonoran Desert overlap. Despite being in a desert, there is a rich riparian habitat due to the river. The preserve is surrounded by the Bureau of Land Management's San Gorgonio Wilderness and is within the Sand to Snow National Monument. Whitewater River is part of the National Wild and Scenic Rivers System.[5]
The river is considered perennial, yet there are a few occasions it goes dry. Heavy storms can cause large debris flows, temporarily covering the river. Eventually, the river establishes a new flow pattern. The water level underground can vary 10 feet depending on whether there have been heavy rains or a lengthy drought.[6]
Large mammals include Desert bighorn sheep, deer, and bear.
Over 200 species of birds have been observed.[7] The Southwestern Willow Flycatcher and the Least Bell's Vireo are endangered.[8] There are also summer tanagers and vermilion flycatchers.
Wildflowers can be excellent in the spring if there was sufficient rain the prior winter. Species include California poppies, bush poppies, and goldfields.[9]
In the 1930s, Whitewater Trout Farm and hatchery was developed on private property at this location.[10] A cattle company grazed its herd on adjacent BLM land for many decades.
In 2006, The Wildlands Conservancy acquired the property. The Conservancy spent a decade restoring the land and creating infrastructure for visitors. They bought the 40,000-acre cattle grazing allotment in Whitewater Canyon and removed the cattle, which restored the clarity of the water. They removed 19 old buildings and built visitor facilities, replacing non-native plants in poor condition with native plants such as cottonwoods and sycamores. The preserve was opened to the public for light recreation.[11]
In 2016, President Obama designated Sand to Snow National Monument, which includes this preserve.[12]
In 2019, on Valentine's Day, a major flood severely damaged the road into the canyon, requiring several months to repair.[13] [14]
In 2020, the Water Fire burned of riparian habitat.[15] [16]
