National Park and NRA waters

Orientation only. Verify current rules with the specific park's compendium before launching. Rules vary significantly by NPS unit. See Waterway Rules hub for jurisdiction overview.

• NPS regulations apply within park boundaries and are separate from state boating law. When you boat on a lake or river inside a national park, NPS regulations govern what is and isn't allowed, in addition to state boating law, which still applies. NPS regulations are published under 36 CFR Chapter 1, with park-specific compendiums covering the rules for each individual unit. Each park or NRA can have substantially different rules.
• NPS rangers have full law enforcement authority on park waters. Rangers can stop vessels, conduct safety inspections, issue citations for both NPS regulation violations and state boating law violations, and make arrests within park boundaries. NPS authority is independent of the state; you can receive a federal citation (prosecuted in federal court) in addition to any state citations for the same incident.
• Access to park waters may require an entry fee. Many national parks charge an entry fee to access the park. This fee applies to boaters accessing park waters from within park land. Some parks issue separate boating permits or require vessel registration with the park in addition to state registration. Check the specific park's website for its entry and boating requirements.
• NPS rules can restrict or prohibit activities that are legal on state waters. Motorized watercraft may be prohibited, restricted to certain zones, or subject to horsepower limits within park boundaries. Jet skis (personal watercraft) are prohibited in many NPS units. Swimming may be restricted to designated areas. Anchoring may be prohibited in certain coves or areas. Each park's compendium lists what is restricted. Check it before assuming state law is the only constraint.

• NPS regulations (36 CFR Ch. 1 + park-specific compendium) apply within park boundaries in addition to state boating law. Each park unit has its own compendium. Check it, not just the general NPS website.
• NPS rangers: full law enforcement authority. Can issue federal citations (federal court) for NPS violations independent of state citations.
• Entry fees: may apply to park water access. Some parks require separate boating registration or launch permits in addition to state registration.
• Common NPS restrictions not present in state law: PWC prohibited, horsepower limits, zone-based motorized restrictions, anchoring prohibitions in designated areas. Review the park compendium before assuming state law governs.

• National Recreation Areas (NRAs) are specifically designated for recreation and often have more permissive rules than national parks. Unlike national parks, which prioritize preservation over recreation, NRAs are established to provide access to specific recreational resources. Lake Mead NRA, Glen Canyon NRA, Bighorn Canyon NRA, and similar units are examples. Motorized boating is generally more broadly permitted in NRAs, but each NRA has its own set of rules.
• NRAs that overlay federal reservoirs have layered authority. Lake Mead NRA sits on a Bureau of Reclamation reservoir. Glen Canyon NRA is also BOR. These waters carry NPS management rules (from the NRA designation), BOR operational rules, and state boating law simultaneously. The most restrictive rule at any given location governs. Check all three layers for any BOR reservoir managed as an NRA.
• Vessel inspection for invasive species is mandatory at many NRAs. National parks and NRAs with reservoirs frequently require mandatory vessel inspection before launch to prevent transport of invasive aquatic species (zebra mussels, quagga mussels, Eurasian milfoil). Vessels coming from other bodies of water may be required to pass through a decontamination station. Failure to present for inspection can result in denial of launch and a citation.

• NRAs: recreation-focused designation, generally more permissive for motorized boating than national parks. Each NRA still has its own regulatory compendium.
• BOR reservoirs managed as NRAs (Lake Mead, Glen Canyon): NPS management rules + BOR operational rules + state boating law all apply. Most restrictive governs.
• Mandatory vessel inspection for invasive species: common requirement at NRA and NPS reservoir launches. May require decontamination before entry. Refusal = denied launch + possible citation.

• NDZ: virtually all national park and NRA waters are designated no-discharge zones. Overboard sewage prohibited, treated or untreated (40 CFR 140.4). Use holding tank. Pump-out stations at park marinas.
• Commercial use on park waters: NPS commercial use authorization required in addition to any state license or certification. Separate application and approval process.
• High-use park launches: advance reservation via recreation.gov during peak season. Some fill well in advance. Check before trailering during summer.

• NPS closes park waters seasonally to protect nesting and breeding wildlife. Seasonal closures in national park and NRA waters are common, covering bald eagle and osprey nesting sites, harbor seal and sea lion haul-outs, shorebird nesting beaches, and bighorn sheep or elk lambing areas near water. These closures typically run from late winter through summer. They are marked by buoys or signs and are strictly enforced; NPS rangers actively patrol closure areas during the season.
• Vessel approach distances to wildlife are regulated in many parks. Even outside formal closure zones, many park units have minimum approach distances for vessels near wildlife, typically 100 to 300 yards for marine mammals and nesting birds. These are not suggestions; they are regulations with enforceable penalties. Turning off the motor and drifting toward wildlife is still an approach.
• Check the park compendium for current seasonal closures before each trip. Closure boundaries and dates can change from year to year based on nesting success, wildlife population changes, or new designations. The park's website and the park compendium (updated annually) are the authoritative sources, not general mapping apps or prior-year trip reports.

• Seasonal closures: eagle/osprey nesting, pinniped haul-outs, shorebird nesting. Buoy-marked, NPS-enforced, typically late winter through summer. Check park compendium annually; closure boundaries change.
• Vessel approach distance regulations: typically 100-300 yards for marine mammals and nesting birds. Enforced. Drifting toward wildlife counts as an approach.
• Current closure map: park website and annual compendium. Not reliably reflected in general mapping apps or prior-season trip reports.

• NPS Water Recreation (nps.gov): Park finder, boating rules overview, seasonal closure info, links to individual park compendiums
• Recreation.gov: Advance launch reservations, entry permits, commercial use authorizations for NPS sites
• EPA No-Discharge Zones by State (epa.gov): NDZ designations including park and NRA waters
