A resort manager walks the beach in March with a supplier’s brochure in hand: a floating obstacle course, a couple of trampolines, a lounge deck for the bar guests. The questions that take time are the ones no brochure answers: who approves it, what lifeguards it needs, what the insurer will ask, and which standard it was built to. If you are looking up water park safety requirements for a lake or sea park, the honest starting point is that there is no single national rulebook. Requirements come from your state and local agencies, your insurer, the equipment maker and the lifeguard program you choose.
In short: check with your state’s amusement ride regulator, health department and natural resources or boating agency, because floating parks fall between their rules in different ways in different states. Ask the supplier which standard the product was tested to, hire lifeguards trained for open water by a recognized program, follow the maker’s anchoring and supervision rules, and get your insurer’s requirements in writing before you buy. This page is general information, not legal advice.
Water park safety requirements: who regulates a floating park?
Land water parks and floating parks are often treated differently, and the gaps are real. Two documented examples:
- Oklahoma: the state Department of Labor requires inflatable amusement rides used commercially or in public to be registered every year, inspected by a certified state inspector and covered by liability insurance. But in a July 2021 notice it said inflatable devices “designed primarily as floating devices to be installed in or on bodies of water” would no longer be inspected annually or registered with the department.
- The main U.S. standard for commercial inflatables: ASTM F2374, the practice for inflatable amusement devices, covers land-based inflatables (dry, wet or both) and specifically excludes inflatable devices designed primarily as floating devices installed in or on bodies of water.
So don’t assume an inspection exists or applies. Ask each agency in writing: the amusement ride regulator, the health department and the agency that permits structures and buoys on your water. The CDC’s Model Aquatic Health Code is guidance for public aquatic venues such as pools, hot tubs and splash pads, and it only becomes law where a jurisdiction adopts it; its overview page doesn’t mention lakes or beaches, so ask your health department whether any of it applies to your waterfront.
Permits for anchoring and marking
- Structures in navigable waters can need Department of the Army permits from the U.S. Army Corps of Engineers (33 CFR 322 defines structures to include permanent mooring structures). Minnesota’s boating guide notes that joint federal-state waters may need a Corps permit.
- Buoys and markers: placing a private aid to navigation on federal waters means applying to the Coast Guard District (33 CFR 66.01-5, form CG-2554). State rules apply too: Minnesota requires public swimming areas, including resorts, to be marked with standard 9 in or larger “Swim Area” buoys spaced no more than 75 ft apart, under a sheriff’s permit.
- Rafts and floats: state rules on swim rafts and floats (size, distance from shore, lights, overnight placement) are summarized on our Coast Guard requirements page.
Boats bring their own rules. The federal recreational equipment rules cover boats rented or chartered for the renter’s own noncommercial use; a vessel carrying passengers for hire falls under separate Coast Guard rules, so tour operators with swim stops should ask their Coast Guard Sector.
Standards to ask your supplier about
In Europe, floating leisure articles have their own standard series. EN 15649-6 covered Class D products such as inflatable climbing structures on water, bouncing platforms, slides, water trampolines and obstacle courses; it was withdrawn in 2017 and replaced by EN ISO 25649-6:2017, and that edition itself has since been listed as withdrawn. Ask your supplier which standard and which edition the product was tested to, and by whom, and get the report. Some makers state that their commercial parks are third-party tested; treat that as the maker’s claim until you’ve seen the paperwork. Aquaglide’s aquapark manual also says its parks aren’t authorized for use with other makers’ products and that connections must be tight with no gaps, which matters if you plan to mix brands.
Lifeguards and supervision
Open water is not a pool, and lifeguard training reflects that. Two programs to know:
- American Red Cross Waterfront Skills: a module added to Red Cross Lifeguarding that teaches lifeguards to prevent and respond to emergencies in nonsurf, open-water areas such as parks, resorts, camps and campgrounds.
- United States Lifesaving Association (USLA): certifies open-water lifeguard agencies, not individuals, against its agency standards; employers train their own lifeguards to those standards.
No maker we found publishes a lifeguard-to-guest ratio for floating parks; staffing comes from your regulator, your insurer and your own risk assessment. Real parks show what operators actually do. A council-approved park at Cosmeston Lakes in Wales (2025) set a minimum age of 8, a minimum height of 1.2 m and an unaided 25 m swim, with lifeguards both in and out of the water. Long Beach’s Alamitos Beach park (2022) was reported to use at least six lifeguards on paddle boards plus a dedicated supervisor. California’s Cali Splash Park lets children 9 and older go alone, while 4 to 8-year-olds need an adult, with no more than two children per adult. Our commercial aquapark guide has more on these parks.
Your insurer’s questions, before you buy
Insurers’ rules differ by carrier and state. Ask these up front, so the answers shape the purchase:
- Will you cover a floating inflatable park, and under which policy type?
- What lifeguard certification, staffing level and supervision plan do you require?
- Do you require third-party test reports, a specific standard or an installation inspection?
- What age, height, swim-test and life jacket rules do you expect for guests?
- What wind, wave and lightning closure rules do you want written into operations?
- Do you require guest waivers, signage, incident reports or daily inspection logs?
Operator checklist
| Area | Who to ask | What to get |
|---|---|---|
| Amusement ride rules | State labor, agriculture or fire marshal office | Whether floating devices are covered, exempt or regulated |
| Swimming venue rules | State or county health department | Water quality, lifeguard and signage rules for your site |
| Placement and buoys | State natural resources or boating agency, sheriff, Army Corps, Coast Guard District | Permits for anchoring, swim-area markers and structures |
| Equipment | Supplier and maker | Test standard and edition, anchoring plan, manuals, warranty terms for commercial use |
| Staff | Red Cross, USLA or other recognized program | Open-water lifeguard training and certificates |
| Cover | Insurer or broker | Written requirements before purchase |
| Crew safety | OSHA | For construction work over or near water, 29 CFR 1926.106 requires life jackets, ring buoys with at least 90 ft of line and a lifesaving skiff |
Daily operations still come back to the basics on the rest of this section: weather and wind closures, keeping boats and exhaust away, and emergency response.
Operator questions
Does a floating water park need a state inspection?
It depends on the state. Oklahoma, for example, stopped inspecting and registering floating inflatable devices in 2021 while still regulating land inflatables. Ask your state’s amusement ride regulator directly.
Is there an ASTM standard for floating inflatables?
The main ASTM practice for inflatable amusement devices, F2374, excludes devices designed primarily to float on bodies of water. Ask your supplier which standard their product was tested to; in Europe that is the EN ISO 25649 series.
Is there a required lifeguard-to-guest ratio?
No maker we found publishes one for floating parks. Get it from your regulator and insurer.
What lifeguard certification do we need for a lake?
Your regulator and insurer decide. Red Cross Lifeguarding with the Waterfront Skills module is built for nonsurf open water such as resort lakes; USLA certifies open-water lifeguard agencies.
