About this run

Santa Margarita River

The Santa Margarita River, located in southern California, is a popular destination for whitewater enthusiasts. The ideal streamflow range for this river is between 200-500 cfs, with higher flows occurring during the winter months. The river is rated as a class II-III, with some sections reaching class IV during high water levels. The river spans over 30 miles, with the most popular segment being the Whitewater River Run, which covers approximately 6.5 miles.

The Whitewater River Run features several exciting rapids and obstacles, including Devil's Hole, a class III rapid with a large boulder in the center, and the Narrows, a narrow section of the river with fast-moving water and large boulders. Other notable rapids include Pinball, S-Turn, and the Elevator.

There are specific regulations in place for the Santa Margarita River, including a permit system operated by the San Diego County Parks and Recreation Department. All boaters must obtain a permit before accessing the river, and there are restrictions on the number of daily permits issued. Additionally, boaters are required to wear personal flotation devices and adhere to Leave No Trace principles.

Overall, the Santa Margarita River offers a thrilling whitewater experience for both novice and experienced boaters. However, it is important to check current streamflow levels and adhere to all regulations to ensure a safe and enjoyable trip.

Whitewater safety

Check the flow before you run
Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
Know your skill ceiling
Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
Wear the right gear
Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
Scout, set safety, and run with a team
Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
Respect the river
Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.
