Lake Perris is an artificial lake completed in 1973. It is the southern terminus of the California State Water Project, situated in a mountain-rimmed valley between Moreno Valley and Perris, in what is now the Lake Perris State Recreation Area. The park offers a variety of recreational activities. Because of this and the lake's proximity to major population centers, it is very crowded during the summer months.

The California Office of Environmental Health Hazard Assessment has issued a safe eating advisory for any fish caught in the Lake Perris due to elevated levels of mercury and PCBs.
Ya'i Heki' Regional Indian MuseumEdit
The Ya'i Heki' Regional Indian Museum tells the story of the monumental State Water Project and focuses on the culture and history of the native peoples of the southern California desert region.
Lake Perris is 1,560 feet (480 m) above sea level and is ringed by hills and small mountains. It impounds 131,400 acre feet (162,100,000 m3) of water behind a 2-mile (3 km) long, 128 foot (39 m) tall, chevron-shaped earthfill dam. The untended areas of Lake Perris may seem rocky and barren at first glance, but harbor a variety of natural wonders.
An artificial reef exists on the lake floor made of old tires. The reef was created to provide a habitat for fish.
Flora and faunaEdit
The predominant plant community, coastal sage scrub, is host to a variety of birds and wildlife. Mule deer, roadrunners, bobcats, coyotes, rabbits, quail, gopher snakes and rattlesnakes may sometimes be seen by day, though they tend to shy away from people. More frequently seen are a wide variety of lizards, rodents, water fowl, and birds of prey. Beautiful displays of wildflowers occur during the rainy season, generally November through April.
The coastal sage scrub community is predominant on the south-facing slopes of the Russell mountains and Bernasconi hills and is characterized by shrubby plants including desert encelia, brittlebush, sagebrush, black sage, white sage, buckwheat, and cacti. Conditions are somewhat shadier on hillsides that face north or northwest so that chaparral plants such as chamise, penstemon, and poison oak are found.
Remnants of the original perennial grasses that once flourished in this region can still be found in the flat interior of the park surrounding the lake, but the majority of plants that now make up the valley grassland community (including Russian thistle) were imported from Europe by early settlers. Riparian areas near springs and seeps, and on east and south lakes include willows, cattails, elderberry and nettles.
More than a hundred species of birds have been spotted at Lake Perris. Many are migratory, and stop at the park briefly during their travels, while others make their permanent residence here. Meadowlarks, loggerhead shrikes, roadrunners, California thrashers, quail, wrens, sparrows, hummingbirds, golden eagles, several varieties of hawks, ospreys, and even bald eagles may be seen. Many varieties of waterfowl use the lake including pintails, widgeons, teals, mallards, shovelers, various geese, and sometimes tundra swans and pelicans. black-necked stilts, avocets, killdeer, willets, kingfishers, egrets, and herons are attracted to the water's edge.
The lake has become a hotspot for freshwater game fishing. Largemouth bass, spotted bass, bluegill, rainbow trout, channel catfish, black crappie, red ear sunfish and carp are all present in the lake. As the climate is a warm one, the California Department of Fish and Game make regular plants of rainbow trout throughout the winter months. The lake records for each of the species are noted here:
- Alabama spotted bass – 9 pounds, 6 ounces
- Florida largemouth bass – 17 pounds, 6 ounces
- Bluegill – 3 pounds, 15 ounces
- Rainbow trout – 7 pounds
- Channel catfish – 30 pounds
Largemouth bass, bluegill, rainbow trout, channel catfish, black crappie, redear sunfish tend to be the primary focus of anglers. The trout usually only bite in the cooler months after the DFG plants.
Day and night, hawks and owls are frequently seen hunting for prey. The bike trail offers an easy and convenient way to see some of the birds and other wildlife of Lake Perris. Early morning or dusk are the best times. Ranger-led hikes are conducted during the spring and early summer months.
Most plants and animals at Lake Perris are well adapted to the hot, dry environment. Chamise leaves are tiny and waxy to minimize water loss due to evaporation. Some grasses and wildflowers rush from bloom to seed in just a few short weeks and are able to complete their life cycle within the brief wet season. Kangaroo rats are so well adapted to dry environments that they seldom drink water, and manage to extract the moisture they need directly from their food.
The plants and animals of Perris Valley have changed considerably over the last two hundred years due to human activity, but its natural history can be intriguing.
There are many recreational activities allowed on, in, and around Lake Perris and in the State Recreation Park. Guided hikes are offered on the trail around the lake, and several camping sites are located near the lake side. The lake is open for boating from 6:00 am to 6:30 pm from Thursday to Monday. Other activities include fishing, picnicking, horse-back riding, swimming (in designated areas), and rock climbing. The park also hosts the annual Big Rock Triathlon at sprint and Olympic distances. There is also a museum on the park grounds.
Lake Perris has hot, dry summers and cool, moist winters. Rainy weather is limited almost completely to the months between November and April. The area lies at a crossroads of weather influences. Coastal fog (and smog) comes from the west, while "Santa Anas"—strong, hot dry winds—come from the deserts to the east and northeast. The average water temperature is 70 °F (21 °C) ; during the summer months, it is bathwater-warm and very pleasant to swim in.
Lake Perris water withdrawalEdit
For several months following July 2005, the water in Lake Perris was drawn down by about 20 percent (about 24 feet) due to safety concerns with the dam. An extensive modern study concluded that the dam could be partially breached if a 7.5 magnitude or higher earthquake were to strike in the area. Heightening the engineers' fears was the fact that the San Jacinto Fault, easily capable of creating a 7.5 tremor, passes just a few miles north of the lake. It may take more than two years for the state to plan a course of action to bolster the dam.
All recreational activities are still allowed, with some restrictions. Most noticeably, the 35 mph (56 km/h) boating zone has been reduced to the area between the dam and Alessandro Island. The area from the island east is now a 5 mph (wakeless speed) area. Swimming is only allowed at Perris Beach (Lots 1, 2, 3, and 4). Reservations for boats are highly recommended in the summer; weekends sell out fast. Since the drawdown there are fewer first-come, first-served spots available for watercraft. In the summer of 2006 (Memorial Day to Labor Day) most reservations sold out a week or two in advance.
2028 Summer OlympicsEdit
The Los Angeles Olympic Bid for the 2028 Summer Olympic Games made an agreement with the Department of Parks and Recreation for the Lake to be host for competitive Canoe-Sprint and rowing competition when Los Angeles hosts the 2028 Summer Olympics. The bid committee preferred Lake Perris to Lake Casitas as Lake Perris is near a larger population base and is in close proximity to UCR for athletes’ accommodations. In February 2019 the International Rowing Federation announced that they had been asked to look at the possibility of using Long Beach Marine Stadium (the 1932 Olympic rowing venue) instead of Lake Perris.
