Folsom Lake Information

Folsom Lake is nestled in the foothills of the Sierra Nevada mountain range in El Dorado, Placer, and Sacramento Counties about 25 miles northeast of Sacramento in the Central Valley of California. Folsom Lake covers 1,500 acres with 75 miles of shoreline and a maximum depth of 250 feet when it is full. The United States Bureau of Reclamation manages the Folsom Project, which includes the Nimbus afterbay reservoir and dam facilities two miles southwest of Folsom Lake, which provides flood control, hydroelectricity, drinking water, and irrigation.

During a 24-hour period, the releases of water from Folsom Dam can vary to meet changing demands for water and power. Nimbus Dam, seven miles downstream from Folsom Dam, stores these releases and re-regulates them to a steady flow downstream in the American River. The Nimbus Dam impounded Lake Natoma, which simply widened the American River for water release control of the Folsom Dam. The Folsom Lake State Recreation Area (FLSRA) extends to surround Lake Natoma.

The California Department of Parks and Recreation manages Folsom Lake, and the FLSRA surrounds Folsom Lake and Lake Natoma. The American River feeds Folsom Lake. Interstate 80, SR 49, and US 50 give access to roads leading to the many park entrances at Folsom Lake. Folsom Lake is in an urban setting, and Sacramento buses provide service to Folsom Lake.

Rolling foothills populated with a variety of oak tree species and flatlands characterize Folsom Lake’s shoreline. Sacramento suburbs surround Folsom Lake and spread through its eastern area on its northern and southern borders. Its western region is more rural. There are a few communities on Folsom Lake’s shores.

When Folsom Lake is at a low water level, remains from Gold Rush settlements are exposed. It is illegal to handle, remove, or destroy artifacts and ruins on the lakebed. These artifacts belonged to immigrants looking for gold on the American River. Federal and state laws protect these sites and artifacts and prohibit disturbing the sites.

History Of Folsom Lake

The Folsom Lake reservoir is formed by the Folsom Dam, which was built in 1955 to control and retain the American River. It is a concrete dam flanked by earth wing dams and dikes with a length of 9 miles. During a 24-hour period, the releases of water from Folsom Dam can vary significantly to meet changing demands for water and power.

Native Americans of the Nisenan tribe inhabited the Folsom Lake region for thousands of years. They lived in permanent villages on the American River in winter. In the summer, they built temporary bark homes. The Nisenan used their local resources found at the river, like acorns and berries, to trade with coastal tribes. They wove baskets from willow, redbud, tule, milkweed, sedge grass, and native grapevine.

Folsom Lake lies on the north and south forks of the American River. Gold discovered on south fork of the American River spawned the 1849 California Gold Rush. Captain John Sutter, a Swiss immigrant to Mexico (today’s California), received a grant from Mexico of 48,000 acres along the American River in 1841. He built Sutter Fort and began to expand his empire. He ran out of building materials and needed a source of lumber. John employed James Marshall, an immigrant from New Jersey, who formed a partnership with John to build a sawmill. They planned to share equally in the profits from the wood.

In January 1847, the mill was halfway built. The crew dug a ditch, called a millrace, to carry river water through the sawmill. The lower end of the ditch, called a tailrace, was too shallow. They dug the tailrace deeper so the water could flow through the mill without stopping, which water carried away sand and dirt and lighter minerals. A heavier metal accumulated in the ditch. The workers hit bedrock at the end of the tailrace and found gold.

James Marshall found the first piece of gold and later wrote, “I went down as usual, and after shutting off the water from the race, I stepped into it, near the lower end, and there, upon the rock, about six inches beneath the surface of the water, I discovered the gold. I then collected four or five pieces and went up to Mr. Scott, who was working at the carpenter’s bench making the mill wheel, and the pieces in my hand and said,

‘I have found it.’

‘What is it?’ inquired Scott.

‘Gold,’ I answered.

‘Oh! No,’ returned Scott, ‘that can’t be!’

I replied positively, ‘I know it to be nothing else.'”

Sutter tried to hold his workers to secrecy, but that was a futile effort. The gold was so plentiful that you could walk along the banks of the South Fork of the American and pick it out of the sand. The Gold Rush of 1849 had a tragic effect on Nisenan Indians. Disease, violence, and 49ers seeking fortunes pushed them out of their homelands. Today, Nisenan descendents still live in the Folsom Lake region.

The waters of Folsom Lake receded to extremely low levels in 2021, and the remnants of an abandoned, flooded Gold Rush village emerged. At this low water level, you can see building foundations, bricks, broken pottery, and rusty tools that were part of Mormon Island. It is illegal to handle or remove any artifacts from Folsom Lake.

Fishing Folsom Lake

Game species in Folsom Lake are bluegill, bream, channel and flathead catfish, black crappie, largemouth, smallmouth, and spotted bass, yellow perch, Chinook and kokanee salmon, green sunfish, and rainbow trout. Folsom Lake is known for bass fishing, but offers good catfish, crappie, sunfish, salmon, and trout fishing. Fishing from shore and kayaks is popular. Folsom Lake levels fluctuate up to 60 feet a year.

The most popular fishing hot spots on the South Fork are New York Creek Cove, Hancock Creek, Jacks Shack, and Deep Ravine. The North Fork has many inlets and coves with submerged boulders that provide good cover for fish. Anglers also like Anderson Island and the Rattlesnake Bar, which is farther up the canyon. In the main body of Folsom Lake, fishing is successful along the shore of the main peninsula between the two river forks and near the dam at Folsom Point and Beal's Point.

Folsom Lake’s waters stay relatively cool all year long. Low water levels prevent largemouth bass from spawning. Spring is the best time for them, and they move to deeper water in the summer. There is little aquatic vegetation in Folsom Lake for bass. Anglers focus on steep points, rip-rap shorelines, rocky reefs, woody cover, and brush piles. Spotted bass offer a great year-round fishery, and bite well in winter, but they will move 40 to 60 feet deep.

Folsom Lake is one of California’s best landlocked Chinook salmon fishing lakes where they reproduce naturally. Late winter and early spring are prime time, and they go down to 100 feet in the summer. Rainbow trout are stocked several times throughout the cooler months in most years, and trout plants may include fingerlings and catchable adults. There are nine boat ramps, one marina, Folsom Lake Marina, and one dry storage facility, Brown’s Ravine. Anglers will find plenty of fishing guide charters on Folsom Lake.

Dogs are not allowed at the swim areas at Negro Bar, Granite Bay, and Beals Point.

The only marina on Folsom Lake, Folsom Lake Marina, has 685 wet slips and 175 dry storage units. There is a wait for slips of one to three years depending on the size of the boat. This marina has a small bait and tackle shop and a marine supply store, plus the only gas dock on the lake. It is open year round unless the water level is too low. It is located at the southeastern end of the lake and has an earth-filled breakwater protecting it from the main part of the lake.
