Can You Jet Ski Across the State Line? What You Need to Know

If you’ve ever looked out across the shimmering waters of Lake Havasu and wondered, “Can I take this jet ski into California?”—you’re not alone. Lake Havasu straddles the border between Arizona and California, and many jet ski riders are curious whether crossing that invisible line on the water is allowed.

The short answer is yes—you can jet ski across the state line—but there are a few rules, safety tips, and regional guidelines you should know before revving that engine and crossing into another state.

Lake Havasu: A Border Lake with Dual Jurisdiction

Lake Havasu is part of the Colorado River, which serves as the boundary between Arizona and California. That means both states have some say over boating and personal watercraft activity in different areas of the lake. Luckily for riders, the regulations are generally similar, but understanding where state-specific rules apply can help you ride smarter (and avoid a ticket).

Jet Skiing Across the State Line Is Legal—With a Few Conditions

You are absolutely allowed to operate a jet ski across the entire surface of Lake Havasu, including the California side. However, once you leave Arizona waters and enter the California portion, you’re subject to California’s boating laws. These may include:

PFD Requirements: Both states require U.S. Coast Guard-approved life jackets for all riders, but California law more strictly enforces jacket fit and wear at all times.

Age Restrictions: California requires operators of PWCs to be at least 16 years old. Riders aged 12–15 may operate only with adult supervision.

Noise and Speed Limits: California is stricter on decibel levels and has specific speed limits in certain coves and marinas.

No-Wake Zones: California designates several no-wake areas, especially near protected beaches and docks.

Be Aware of Buoys and Local Signage

Many parts of Lake Havasu clearly mark zones with buoys, including state jurisdiction lines, no-wake areas, and restricted zones. Keep an eye out for signs indicating when you’re entering California-controlled waters or areas with special restrictions (such as wildlife sanctuaries or swimmer zones).

Borderline Must-Visit Spots

If you’re exploring both sides of the lake, here are a few California-side highlights to consider for your ride:

Cattail Cove State Park: A quieter beach with scenic coves perfect for a mid-ride break.

Havasu National Wildlife Refuge: While motorized access is limited, parts of the refuge can be admired from just outside the boundary lines.

Steamboat Cove: Popular among riders and accessible from both states, it’s a social spot great for anchoring and floating.

Cross-Border Jet Skiing Tips

Bring ID: If you’re stopped by marine patrol or enforcement from either state, having identification is helpful.

Carry a Whistle or Sound Device: Required in both Arizona and California for emergency signaling.

Follow Rental Guidelines: If you’re using a rental jet ski, check with the provider to confirm if you’re allowed to cross into California waters. Most allow it, but it’s always good to ask.

Watch the Time: Jet ski rentals often have time limits—don’t lose track of your return deadline while exploring the California side!

Riding Smart Across State Lines

Jet skiing across state lines is one of the unique experiences that makes Lake Havasu so special. As long as you stay aware of differing regulations, pay attention to signage, and ride responsibly, you’re free to explore every scenic inch of this iconic desert lake.
