Boating Under the Influence at Lake Mead

The charge

Lake Mead National Recreation Area is administered by the National Park Service, so the standard applied on the water there comes from title 36 of the Code of Federal Regulations. The operative provision is 36 CFR 4.23, and it prohibits two distinct things.

The first is operating, or being in actual physical control, while under the influence of alcohol, a drug, or a combination of them, to a degree that renders the person incapable of safe operation. This does not require any number at all. There need be no breath test and no blood draw. It is a charge about condition and capability, built out of what the ranger observed: the stop, the balance, the speech, the field tests, what was in the cooler, what you said.

The second is the per se standard: an alcohol concentration of 0.08 grams or more per 100 milliliters of blood, or 0.08 grams or more per 210 liters of breath. Here the number is the offense. The regulation also notes that state law may impose stricter limits.

Those are two separate ways of losing, and the government does not have to pick one. Read the violation notice or the complaint to see which subsection you are charged under, and whether you are charged under both.

Prescribed medication is covered

This is the part that surprises people most. 36 CFR 4.23(b) reaches operating under the influence of a drug that was lawfully prescribed. Having a valid prescription, filled by a pharmacy, taken as directed, is not by itself an answer to the charge — the question the regulation asks is about your condition while operating, not about whether the substance was legally yours.

If any part of your case involves medication, bring the bottles, the prescriptions, the pharmacy records, and the names of the prescribing physicians to a lawyer at the outset. When you took it, how much, and what you were told about it are facts worth writing down now, while you still remember them precisely.

Where the case goes

A 36 CFR 4.23 charge at Lake Mead is heard in the United States District Court for the District of Nevada, ordinarily before a magistrate judge. In Las Vegas that is the Lloyd D. George Courthouse, 333 Las Vegas Blvd. South. Northern Nevada cases go to the Bruce R. Thompson Courthouse in Reno. Federal violation notices for offenses on federal property are processed through the Central Violations Bureau, the CVB — a processing center for the paperwork and payment, not the body that decides anything.

If Box A on the face of the violation notice is checked, your appearance is mandatory. Otherwise a federal citation can usually be resolved without appearing, and Federal Rule of Criminal Procedure 58(d)(1) allows the court to accept a fixed-sum payment in lieu of the defendant’s appearance and end the case. For an impaired-operation allegation, do not treat that option as a shortcut without advice. It is a disposition of a criminal case.

How the penalty compares to a Nevada DUI

The National Park Service penalty ceiling comes from 36 CFR 1.3(a), which routes to 18 U.S.C. § 1865: a fine and imprisonment of not more than six months. Six months puts the offense inside the petty-offense definition in 18 U.S.C. § 19 — which triggers Federal Rule of Criminal Procedure 58(b)(2): no right to a jury trial for a petty offense, and no right to appointed counsel for a petty offense for which counsel is not required.

Nevada’s driving-under-the-influence scheme is a different animal. It uses the same 0.08 threshold (NRS 484C.110(1)(b)) but its own penalty structure, which escalates by offense within seven years (NRS 484C.400(1)).

The Nevada column is there for contrast, not because it applies to you. A federal case at Lake Mead is prosecuted by the United States, in a federal courthouse, under federal rules. Whether a federal disposition has any consequence in the Nevada system — for a license, or as a prior in some later state case — is a question to put directly to a lawyer, not one to reason out from a comparison table.

Records and sealing

People ask about sealing early, usually before the case has moved at all. What can be said here is narrow, and it concerns Nevada records: Nevada’s sealing statute, NRS 179.245(6), lists a felony under NRS 488.410, together with NRS 488.420 and NRS 488.425, among the convictions that can never be sealed in Nevada.

That list is a Nevada rule about Nevada records. What a federal disposition under 36 CFR 4.23 would mean for your own record, for any license you hold, or for immigration status is a separate question, and it deserves a direct answer from a lawyer who has read your paperwork rather than a general one from a webpage. Ask it before you resolve the case, not after.

What to do now

Write down the day while it is fresh: where the vessel was, who was operating, who else was aboard, how long you had been on the water, what you drank or took and when, what tests you were asked to do and on what surface, whether the water was moving, what you were told, and what you said. Keep the violation notice and photograph both sides. Keep the rental agreement, the receipts, and any photographs or video from the day, including other people’s.

Talking to a lawyer about it

Andrew Wong practices primarily in federal criminal defense at Vegas Golden Law. He was an assistant federal public defender in the District of Nevada from 2018 to 2022 and in the Eastern District of California from 2017 to 2018, and clerked for the Hon. Cam Ferenbach of the District of Nevada. The ACLU of Southern Nevada invited him to speak on federal public land offenses.
