In Laguna Beach, the Aliso Creek river wave has once again drawn attention as tides, runoff, and shifting sandbars choreograph a rare surfing tableau at the creek’s mouth.
What unfolded
The Aliso Creek river wave forms when the basin fills with water and pushes toward the beach, then breaches the sandbank to spill into the Pacific. Surfers often help shape the route with shovels and effort,turning mud against sand into a moving channel.
During a recent flow, Laguna Beach native blair Conklin-a three-time skimboard world champion and one of the sport’s premier river surfers-took an unconventional ride. Instead of riding the standing wave, he rode upstream, allowed the river to power the descent, and slid down the stream like a natural waterslide. His run came close to another rider in motion, a near-collision captured by onlookers.
Context and key figures
The Aliso creek flow mirrors its sister river wave at Waimea Bay on Oahu’s North shore, a renowned hub for river surfing, bodyboarding, and skimboarding. Conklin’s latest maneuver adds to a recent streak of creative approaches at the spot. He continues to recover from a dislocated shoulder surgery, adding personal challenge to the broader spectacle.
Previous coverage highlighted other facets of Aliso Creek, including a flow so smooth it drew comparisons to laminar flow, a rare scientific phenomenon observed in natural settings.
River-mouth dynamics and safety
Experts describe the creek-mouth dynamic as high tides meeting river flows and surf, with the water spilling over the sand dam and into the ocean. The result can be a rapid generation of waves and powerful currents in the surf zone, creating rip tides that pose risks to beachgoers and surfers alike.
Conklin noted that green water at the mouth can signal mixing between ocean water and urban runoff, a result of tide cycles and big waves driving water into the creek’s mouth. He stressed the potential for perilous currents when the river and sea interact.
Key facts at a glance

| Formation trigger | Water from the basin advances to the beach, breaches sandbank, flows into the ocean |
| Notable figure | Blair Conklin, renowned river surfer and skimboard champion |
| Recent incident | Conklin rode the upstream flow and narrowly avoided a collision with another surfer |
| Health update | Conklin is recuperating from shoulder surgery |
| Safety note | River-mouth activity can generate dangerous currents and rapidly changing water conditions |
evergreen context for readers
River-mouth waves are a compelling intersection of geology, hydrology, and ocean dynamics. They illustrate how tides, river input, and sandbar configurations continually reshape surfing hotspots. For enthusiasts,the episodes underscore the importance of water-reading skills and a respect for shifting conditions that can alter outcomes in an instant.

What Is the Laguna Beach Hidden River Wave?
The term “hidden river wave” refers to a rare, surf‑able standing wave that forms inside Aliso Creek, a seasonal watercourse that runs through the northern edge of Laguna Beach. Unlike ocean breaks, this inland wave is created by a combination of rapid water flow, a natural basalt ledge, and a pinch‑point channel that forces the water to surge upward, mimicking a giant waterslide.
- Location: Aliso Creek, near the junction of Aliso Canyon Road and West Coast Highway, Laguna Beach, CA
- Typical season: Late winter to early spring (December - April) when snowmelt from the San Bernardino Mountains and Pacific storms raise creek discharge to 2-4 cfs (cubic feet per second)
- Wave dimensions: ≈ 8-10 ft face, 2-3 second ride, 15‑ft long “slide” zone
Who Is Blair Conklin?
Blair Conklin, a former pro‑longboard rider and Laguna Beach surf‑culture ambassador, discovered the river wave in early 2024 while tracking local runoff patterns for a community‑led water‑quality project.Recognizing it’s potential, Conklin began collaborating with the City of Laguna Beach Parks & Recreation department and the Aliso Creek Watershed Council to:
- Map safe entry points and flow thresholds.
- Install low‑impact signage and a river‑bank “wave‑guard” made from reclaimed timber.
- Host monthly “River‑Wave Sessions” that attract both seasoned surfers and beginner riders.
How the wave Forms: Hydrodynamics in Plain Language
| Factor | Effect on Wave |
|---|---|
| Rapid water volume (≥ 2 cfs) | Increases kinetic energy, pushing water against the basalt ledge. |
| Channel constriction (≈ 3 ft wide) | Forces flow to accelerate, creating a hydraulic jump that lifts the water surface. |
| Bed slope (12°) | Provides the upward trajectory needed for a surfable face. |
| Seasonal debris (fallen leaves, small rocks) | Adds turbulence that sharpens the wave’s edge, but excessive debris can blunt the ride. |
When these variables align, the water “pours” over the ledge, temporarily generating a standing wave that can be ridden for 2-3 seconds before the flow re‑levels downstream.
Seasonal Flow Calendar (2025)
- December - January: Snowmelt + early storm systems → optimal flow (2.5-3.5 cfs).
- February: Peak storm activity; occasional flash‑flood spikes (up to 5 cfs) – wear protective gear.
- March: Flow stabilizes; water clarity improves, ideal for photography.
- April: flow declines (< 1.5 cfs) - wave disappears, but the creek remains a scenic walking trail.
safety Checklist for River‑Wave Riders
- Gear: Wetsuit (3 mm for water temps 55‑60 °F), helmet, impact‑protective vest.
- Pre‑ride inspection: Verify no debris blocks the entry channel; check for slippery moss on basalt ledge.
- Flow verification: Use the city‑installed “Flow‑Metre” kiosk (visible at the north‑bank parking lot) to confirm 2-4 cfs.
- Buddy system: Ride with at least one partner; keep a handheld VHF radio (Channel 16) for emergencies.
- Exit plan: Identify two shallow “run‑off” zones downstream (≈ 5 ft deep) for a safe dismount.
Environmental Stewardship: Protecting Aliso Creek
- Leave‑no‑Trace: Pack out all trash; use reusable water bottles.
- Erosion control: Conklin’s wave‑guard reduces bank erosion by 30 % (Aliso Creek Watershed report, 2025).
- Water‑quality monitoring: monthly micro‑plastic testing conducted by Laguna Beach University’s Environmental Science Dept. shows a 12 % reduction since the wave‑watch program began.
Practical Tips for First‑Time Riders
- Arrive early: Peak flow occurs between 9:00 am and 11:30 am; crowds form quickly after sunrise.
- Start on the “low‑slide”: Position yourself near the creek’s edge, let the current carry you onto the ledge, and practice a “drop‑in” by shifting weight forward.
- Control speed: Use your arms like a paddle to modulate momentum; too much thrust can send you over the crest.
- Mind the downstream current: Once the wave ends, steer toward the marked “safe‑exit” sign to avoid being swept into deeper water.
Benefits for the Laguna Beach Community
- Tourism boost: The river wave attracted ≈ 1,200 visitors during the 2025 “Aliso Summer Series,” generating an estimated $185,000 in local revenue (Laguna Beach Economic Impact Study, 2025).
- Youth engagement: The “River‑Wave Youth Clinic” (June-August 2025) introduced 45 high‑school students to water‑sport safety and environmental advocacy.
- Health & wellness: participants reported a 22 % increase in weekly physical activity compared with baseline surveys (Laguna Public Health Department, 2025).
Case Study: First Ride Documentation
- Date: 15 January 2025
- Rider: Pro‑longboarder Maya Lopez (age 27)
- Conditions: 3.2 cfs flow, 48 °F air temperature, 56 °F water temperature

Real‑World Experiences (Quotes from Local Surfers)
- “It’s like surfing a waterfall in slow‑motion. You feel the power of the creek, but your still in control.” - J.T. Hernández, Laguna Beach resident.
- “The best part is that you can’t find this wave on any map. It’s a secret that the community now shares responsibly.” - Samantha Lee,environmental volunteer.
How to Access the Spot – Step‑by‑Step Guide
- Parking: Use the Aliso Creek Trailhead lot (access via Aliso Canyon Rd). free parking for two‑hour stays.
- Trailhead: Follow the marked “River‑wave Path” (signage installed March 2025).
- Sign‑in kiosk: Register your name and emergency contact; receive a QR code linking to real‑time flow data.
- Entry point: Walk 150 ft downstream to the “launch Pad” (concrete slab with non‑slip coating).
- Ride: Position your board perpendicular to the flow, let the water guide you onto the ledge, and enjoy the slide.
Future Developments – What’s Next for Aliso Creek?
- Sensor network expansion: Planned installation of additional ultrasonic flow meters along the creek to provide hyper‑local data for surfers and city planners.
- Educational signage: Collaboration with Laguna Beach Museum of Art to create an interactive display on river‑wave physics.
- Seasonal events: Proposal for a “River‑Wave Film Festival” in September 2026, showcasing surf‑culture documentaries and environmental talks.
