You trailer the boat out of Farmington, launch at Pine, and run up the lake toward Colorado. Along the way the water may be shallower than it was last summer, the afternoon wind may pick up, and you cross a state line without noticing. Each of those moments raises an insurance question that most Navajo Lake owners never ask until something goes wrong.
Navajo Lake boat coverage, in 60 seconds
Navajo Lake boat owners should review five things: liability limits for guests and other boaters, how the hull is valued, whether the policy's navigation area includes the lake's Colorado waters, coverage for the trailer on the drive from Farmington, and what the slip or storage agreement asks for. Low water, wind and two states' rules make each one matter here.
- Two states, two rule books. Colorado requires an Aquatic Nuisance Species stamp on motorboats and sailboats used on its waters, including the lake's Colorado end: $25 for residents, $50 for nonresidents (Colorado Parks and Wildlife).
- Low water is a hull risk. Colorado Parks and Wildlife warns of "new water hazards" from historic low water at Navajo State Park.
- Ramps change. New Mexico State Parks' lake conditions page (updated October 6, 2026) listed the Pine ramp open and the Sims ramp temporarily closed for sediment removal.
- Your slip contract decides. We found no published insurance requirement from the Navajo Lake marinas, so read the agreement you sign.
- The drive counts too. A boat policy can cover the trailer; ask how your auto policy treats what you tow.

Navajo Lake is where a lot of San Juan County families spend their summer weekends, and it is not an easy lake. It sits high in the desert, it stretches north into Colorado, its water level swings from year to year, and the nearest help can be a long way up a canyon arm. A boat policy written for a generic lake can leave gaps on this one. Our agents in Farmington insure boats, pontoons and the trucks that tow them, and these are the questions we walk through with Navajo Lake owners before the season starts.
Where Is Navajo Lake, and Why Does It Shape Your Boat Coverage?
The short answer: Navajo Lake is a large, remote reservoir on the San Juan River east of Farmington that crosses into Colorado, so one day on the water can involve two states, long canyon arms and fast-changing weather.
The Bureau of Reclamation built Navajo Dam between 1958 and 1962 and dedicated it on September 15, 1962. When full, the reservoir covers about 15,610 acres and holds about 1,708,600 acre-feet of water, with "several miles extending into southern Colorado." Reclamation places the dam about 34 miles east of Farmington, and New Mexico State Parks describes the park as 40 miles east of Farmington. State Parks calls Navajo the second largest lake in New Mexico, with park elevations from 5,600 to 6,600 feet and a deepest point near the dam of nearly 400 feet.
On the New Mexico side, boaters launch at two concrete ramps. Pine has six launching lanes and two 90-foot courtesy docks; Sims Mesa has three lanes and one 60-foot dock. Navajo Dam Marina, at the south end on NM 511, is the largest full-service marina on the lake, offering fuel, slip and buoy rentals, dry storage, a sewer pump-out and boat repair. Sims Lake Marina is the other New Mexico concessionaire. In Colorado, Two Rivers Marina sits about 35 miles up the Main Arm and is reached by road from Ignacio.
Distance is the insurance issue. State Parks warns that the lake's "twisting lake arms" and S-curves make night travel difficult, that cell service is spotty, and that VHF radio may not reach into some canyons. That is why we ask Navajo Lake owners about towing and emergency services coverage, and about where their policy says the boat may be used.
If you are new to the area, our Farmington insurance guide covers the rest of the household picture, from cars to homes.

Do You Need Colorado Paperwork to Boat the Upper End of Navajo Lake?
The short answer: If your motorboat or sailboat will be on the Colorado end of the lake, plan on an Aquatic Nuisance Species stamp, plus an inspection if you launch at the Colorado ramp; a New Mexico boat may operate in Colorado for up to 60 days on its home-state registration.
Colorado Parks and Wildlife (CPW) says vessels from other states may be operated in Colorado for up to 60 days with a current registration from the owner's state. Separately, "Motorboats and sailboats must have an Aquatic Nuisance Species Stamp before launching in Colorado," and the stamp law, C.R.S. 33-10.5-104.5, applies to anyone who will operate or use a motorboat or sailboat on Colorado waters, so a boat that launches in New Mexico and runs north needs one too. The stamp costs $25 for residents and $50 for nonresidents, runs for the calendar year and expires December 31. At Navajo State Park, CPW lists mandatory boat inspections at the ramp, says out-of-state boats "may launch with a valid registration from any state," and exempts vessels that are both hand-launched and human-powered from those inspections.
New Mexico has its own rule. Under 19.30.14.12 NMAC, the Department of Game and Fish's aquatic invasive species rule (replaced effective July 11, 2017):
- It is unlawful to knowingly avoid an established check station.
- A boat transported into New Mexico or registered in another state may not be launched without first being inspected and/or decontaminated.
- Owners of boats 26 feet or longer must notify the department's aquatic invasive species coordinator at least 14 days before transporting them into or within New Mexico.
- Drain plugs must be out while a boat is transported on a public road in New Mexico.
New Mexico State Parks adds that out-of-state boats may use state waters for up to 90 days before they must be registered in New Mexico or leave.
| Rule | New Mexico side | Colorado side |
|---|---|---|
| Out-of-state boats | Up to 90 days, then register or leave (State Parks) | Up to 60 days on a home-state registration (CPW) |
| Invasive species | Inspection and/or decontamination before launch for boats from out of state | ANS stamp plus mandatory inspection at the Navajo State Park ramp |
| Drain plugs | Must be out on public roads | See CPW rules |
Here is the insurance part. The Maryland Insurance Administration's boat owners guide notes that "some watercraft policies contain a navigational waters limitation," and that operating outside that area may void coverage for a loss. Before you run north past the state line, ask us to confirm your policy's navigation territory includes Colorado waters. Our agency is licensed in both New Mexico and Colorado, so we can look at both sides.

What Happens to Your Boat Coverage When Navajo Lake Runs Low?
The short answer: Low water exposes rocks, sandbars and debris, closes or moves ramps and docks, and turns a routine run into a grounding risk, so the physical damage side of your policy matters more in dry years.
Navajo Lake's level has a history of dropping hard. In June 2018, The Journal in Cortez reported that low water forced Navajo State Park in Colorado to remove its docking and marina facilities, along with fuel and pump-out services, because the docks, marine store and boat houses would risk being damaged if they stayed in place. In CPW news published April 4, 2026, park manager Jon Meats said, "Our water level will be low this year on the Colorado side," and asked boaters to use caution because flooding in fall 2025 "introduced more debris." CPW's park page now reads: "Due to historic low water levels at Navajo State Park's reservoir, please stay alert to new water hazards."
The New Mexico ramps have their own limits. State Parks lists the bottom of the Sims Mesa ramp at 6,000 feet and the bottom of the Pine ramp at 5,997 feet. Those are fixed numbers, which is why a falling lake can shorten or close a ramp. On its lake conditions page, last updated October 6, 2026, State Parks wrote: "Pine ramp is open; however, the Sims ramp is temporarily closed for sediment removal," adding that heavy rains "caused ramp structure undercutting and sediment deposits, but access remains available." Check the lake conditions page before every trip.
| Navajo Lake hazard | Coverage to review | Priority |
|---|---|---|
| Submerged rocks, sandbars and flood debris in low water | Physical damage (hull, motor, lower unit) | High |
| Hitting another boat, a dock or a swimmer | Liability and medical payments | High |
| Breakdown far up a canyon arm | Towing and emergency services | Medium |
| Storm damage at a slip or buoy | Physical damage; check slip agreement | Medium |
| Boat sinks or must be removed | Wreck removal | Medium |
| Trailer trip on US 64 and NM 511 | Trailer coverage; auto liability while towing | Review |
A boat owners policy can cover physical loss to the property "(watercraft, motors, equipment and trailers) unless the cause of loss is specifically excluded by the language of the policy," according to the Maryland guide. The exclusions are the part to read. Ask us how your policy treats striking a submerged object, damage to the lower unit, and wear that shows up only after a hard season.
Two neighbors from Aztec run similar pontoon boats during a low-water summer, and both clip a rock bar that was underwater the year before, damaging a propeller and lower unit. The first carries liability only. The second carries physical damage coverage with a deductible she can afford. Liability pays for harm you cause to others, so the first owner pays for his own repair. The second files a claim and pays her deductible. Same rock, very different week.

How Do Wind and Summer Storms on Navajo Lake Affect Your Coverage?
The short answer: Storms can build quickly and push large waves toward the marina, so ask how your policy handles storm damage at the slip, sinking at a mooring and emergency help on the water.
New Mexico State Parks keeps wind warning lights at the Pine site, Sims Mesa and Miller Mesa. Its boating page says summer storms usually approach from the west and that north-south arms and coves offer shelter. It also warns that severe storms from the northeast "can generate major waves at the Pine Marina," making loading dangerous. When that happens, State Parks advises moving to the lee side of the lake and anchoring or idling until the storm passes.
The park also recommends carrying a Personal Location Beacon when possible and filing a float plan before you head out. The marina store monitors VHF channel 16 and relays information to rangers. Those habits keep people safe. Insurance is what pays for the aftermath, and a few coverage details matter when weather is the cause:
- Storm damage while moored. A boat tied in a slip or on a buoy can be damaged by waves, by other boats or by the dock itself. Physical damage coverage is what responds to your own boat.
- Emergency services and towing. The Maryland guide lists "emergency services, wreck removal" and "towing" among the additional coverages a boat owners policy may provide.
- Life salvage. The North Carolina Department of Insurance notes that some policies include a "life salvage" provision that "will reimburse the costs incurred by others to save the lives of insureds."
- Your gear. North Carolina's regulator also warns that personal effects not used in the normal operation of the boat "are not covered" under the policy it describes, while some insurers offer separate coverage for fishing equipment, phones and computers.
Weather is also a liability question. If your boat breaks loose in a storm and damages a neighbor's boat or the dock, the claim may come to you.

Does a Navajo Lake Slip or Buoy Rental Require Boat Insurance?
The short answer: Check your slip agreement: we could not find a published insurance requirement from the Navajo Lake marinas, so the contract you sign is the document that answers it.
Moorage on Navajo Lake runs through the concessionaires. New Mexico State Parks lists slip and buoy rentals and dry storage at Navajo Dam Marina, and boat rentals and storage at Sims Marina. On the Colorado side, State Parks lists slips and mooring balls at Two Rivers Marina; check current availability with the marina, since CPW's park page lists the dock as seasonal. For current marina contacts and services, see the New Mexico State Parks Navajo Lake page.
We looked for published slip contracts or rules from these marinas and the park agencies and did not find insurance terms posted online. That does not mean there are none. It means you should read the agreement in front of you and look for three things:
- Proof of insurance. Does the marina ask for a certificate or declarations page before you tie up?
- Minimum liability limits. Is a specific dollar amount named?
- Additional insured or indemnity language. Does the contract ask you to name the marina on your policy, or to cover the marina's losses caused by your boat?
Bring the agreement to our Farmington office or email us a photo of it, and we will tell you whether your current policy meets it. Even without a contract requirement, a boat in a slip sits next to other people's property. Liability coverage applies when you are "legally responsible for causing bodily injury and/or property damage to others while operating the watercraft," as the Maryland guide puts it, so ask us how your policy responds to damage your boat causes while it is tied up, not only while it is under way.

Which Boat Coverages Matter Most for Navajo Lake Owners?
The short answer: Start with liability and physical damage, then add the pieces that fit a remote, two-state lake: uninsured boater, medical payments, towing and emergency services, and wreck removal.
New Mexico State Parks' registration and boating pages don't list an insurance requirement for recreational boats, so the coverage on your boat is mostly a choice you make, unless a contract you signed says otherwise. These are the pieces we review with every owner:
Liability
Pays for injuries and damage you are legally responsible for causing to others while operating the boat: guests, swimmers, other boats, docks.
Physical damage (hull)
Covers the boat, motors, equipment and trailer. Agreed value pays an amount set in advance; actual cash value subtracts depreciation.
Uninsured boater
North Carolina's regulator notes uninsured boat coverage "might be available." Ask whether your policy offers it.
Medical payments
Pays reasonable medical and funeral expenses from a boating accident; who it covers depends on the policy. North Carolina's regulator says it is usually limited to $1,000 per person, though the limit may be increased.
Towing and emergency services
Help when the boat quits far from the ramp, which on a lake with spotty cell service is worth asking about.
Wreck removal
A provision "to remove or destroy a wrecked or sunken vessel, if required by law," per North Carolina's consumer guide.
Don't lean on a homeowners policy for a boat you run at Navajo. The Maryland guide says property coverage for a watercraft under a homeowners policy "may be capped at $1,000" and generally applies only to small sailboats and low-horsepower outboards. If you have significant assets to protect, our New Mexico umbrella insurance guide explains how extra liability works; ask us whether an umbrella would sit over your boat liability. Owners who keep the boat, the truck and the house with us can also review everything at once, as our bundling guide explains.

What Should You Do After a Boating Accident on Navajo Lake?
The short answer: Get help first, notify law enforcement right away, and on the New Mexico side file a written report with New Mexico State Parks within 48 hours if someone is hurt beyond first aid, dies or disappears, or damage tops $100.
New Mexico State Parks says the operator must immediately notify local law enforcement after a boating accident and submit a written report to State Parks within 48 hours when a person dies, an injury needs medical treatment beyond first aid, a person disappears from a vessel, or vessel or property damage is more than $100 or a vessel is a complete loss. Failing to comply is a petty misdemeanor with a penalty of up to $500. If the accident happens on the Colorado end of the lake, follow the instructions of Colorado Parks and Wildlife staff.
Source: U.S. Coast Guard, 2024 Recreational Boating Statistics, released July 1, 2025 →
The Coast Guard's 2024 report is a national picture, not a Navajo Lake count, but two findings are worth knowing. Alcohol was the leading known contributing factor, linked to 92 deaths, or 20% of fatalities. And about 70% of deaths happened on boats whose operator had not received boating safety instruction. The 2024 death count was the lowest since the Coast Guard began collecting these statistics more than 50 years ago.
For the insurance claim, a few steps help:
- Photograph the boats, the dock or shoreline, and any injuries, and note your location on the lake.
- Get names and contact details for the other operator, passengers and witnesses.
- Call us before you authorize major repairs, so the claim is set up correctly from the start.
If the accident happens on the road while towing, the steps look more like a car crash. Our guide to what to do after an accident in New Mexico walks through them.

Is Your Boat Covered on the Trailer Between Farmington and the Lake?
The short answer: A boat policy can cover the trailer itself, but check how your auto policy handles liability while you tow, and pull the drain plug before you leave the ramp, because New Mexico's rule requires it on public roads.
Most Navajo Lake trips start on the highway. New Mexico State Parks' directions run from Bloomfield 25 miles east on US 64, NM 511 and NM 539; Albuquerque boaters come north on US 550 to Bloomfield first. That is a long tow over two-lane roads, often with a heavy boat behind a pickup.
Two different policies can be involved:
- The boat policy. North Carolina's consumer guide lists "the boat's trailer" among the items physical damage coverage can include, and the Maryland guide says boat owners policies cover "the trailers used for towing them." If the trailer is damaged in a crash, this is the policy to check first. Confirm the trailer is listed on your declarations page.
- The auto policy. If your rig causes a crash on NM 511, start with the tow vehicle's auto policy. How it treats a trailer you tow depends on its wording, so ask us to check yours rather than assume. Our Farmington car insurance guide covers the local driving picture.
The road itself has a boating rule. Under 19.30.14.12(F) NMAC, it is unlawful to have a drain plug or barrier in place that prevents water from draining from bilge lines, ballast tanks, live wells and similar compartments while the boat is transported on a public road in New Mexico. If your boat is 26 feet or longer and coming from out of state or moving within New Mexico, the same rule asks you to notify the Game and Fish aquatic invasive species coordinator at least 14 days ahead.

How Should You Insure a Navajo Lake Boat Over the Winter?
The short answer: Keep physical damage coverage in place while the boat sits, tell us where it is stored, and ask how your policy treats theft, freeze damage and any seasonal provisions before you change anything.
The season winds down differently on each side of the lake. CPW says the Navajo State Park ramp in Colorado closes for the season on November 1 for repairs, and the Two Rivers Marina store closes for the season on October 31. On the New Mexico side, State Parks' lake conditions page (updated October 6, 2026) reports "No projected closures this winter." Navajo Dam Marina offers dry storage, and Sims Marina lists storage as well.
Where the boat spends the winter changes the questions:
- At a marina. Read the storage agreement for who is responsible for damage in the yard, and confirm your policy covers the boat at that location.
- In your driveway or a barn. The homeowners policy is not a substitute for boat coverage. As the Maryland guide notes, homeowners property coverage for a watercraft "may be capped at $1,000." If you are reviewing the house too, our Farmington home insurance guide covers local home risks.
- Still in the water. If the boat stays in a slip, the storm and sinking questions from the weather section still apply in winter.
Some owners ask about dropping coverage for the off-season to save money. Before you do, remember that theft, vandalism and damage to a stored boat can happen in January as easily as July. Ask us whether your policy has a seasonal or lay-up option, what it keeps in force, and what freeze damage it covers or excludes. A boat that sits through a high-desert winter at 6,000 feet should be winterized according to the manufacturer's instructions, and your policy wording tells you what happens if it is not.

Frequently Asked Questions About Navajo Lake Boat Insurance
Do I need a Colorado ANS stamp to boat on Navajo Lake?
Plan on one if your motorboat or sailboat will be on the Colorado end of the lake. Colorado law (C.R.S. 33-10.5-104.5) requires the stamp to operate or use a motorboat or sailboat on Colorado waters, and Colorado Parks and Wildlife says it is needed before launching in Colorado. It costs $25 for residents and $50 for nonresidents and expires December 31 each year. At Navajo State Park near Arboles, boats also go through a mandatory inspection at the ramp; craft that are both hand-launched and human-powered are exempt from that inspection. CPW says boats from other states may be operated in Colorado for up to 60 days on a current home-state registration. If you launch at Pine or Sims Mesa in New Mexico, follow New Mexico's inspection rules too.
Do Navajo Lake marinas require insurance to rent a slip?
We could not find a published insurance requirement from the Navajo Lake marinas, so check your slip agreement. New Mexico State Parks lists slip and buoy rentals at Navajo Dam Marina and slips and mooring balls at Two Rivers Marina in Colorado. Read the contract for three things: whether you must show proof of insurance, whether it names a minimum liability limit, and whether it asks you to add the marina to your policy or cover its losses. Even without a requirement, your boat sits beside other people's property, so liability coverage that responds while the boat is tied up is worth having. We are happy to review the agreement with you.
Will my boat policy cover me on the Colorado end of Navajo Lake?
It depends on your policy's navigation area. The Maryland Insurance Administration's boat owners guide notes that some watercraft policies contain a navigational waters limitation, and that operating outside that area may void coverage for a loss. Navajo Lake extends several miles into southern Colorado, according to the Bureau of Reclamation, so a run up the Main Arm toward Two Rivers Marina takes you across a state line. Ask your agent to confirm that Colorado waters are inside your navigation territory before the season starts. Our agency is licensed in both New Mexico and Colorado and can review this with you.
What should I do after a boating accident at Navajo Lake?
Get help first and notify local law enforcement immediately. On the New Mexico side, New Mexico State Parks requires the operator to submit a written report within 48 hours when someone dies, an injury needs treatment beyond first aid, a person disappears from the boat, or vessel or property damage is more than $100 or a vessel is a complete loss. Failing to comply is a petty misdemeanor with a penalty of up to $500. For your claim, photograph the damage and the scene, note your location on the lake, collect names of everyone involved and any witnesses, and call your agent before authorizing major repairs.
Does boat insurance cover hitting a rock when Navajo Lake is low?
Only if you carry physical damage coverage, and then according to your policy's terms. Liability coverage pays for harm you cause to others, not damage to your own boat. A boat owners policy can cover physical loss to the boat, motors, equipment and trailer unless a cause of loss is excluded, so read the exclusions and ask how your policy treats striking a submerged object and damage to the lower unit. Low water is a real issue here: Colorado Parks and Wildlife warns of new hazards from historic low water at Navajo State Park, and fall 2025 flooding added debris to the lake.
Related Questions
The Bottom Line on Navajo Lake Boat Insurance
The short answer: Navajo Lake asks more of a boat policy than most lakes: two states, low-water hazards, fast weather and a long tow, so review liability, hull value, navigation territory, trailer coverage and your slip agreement before the season.
Buy the Colorado ANS stamp if you launch up north, get inspected when the rules call for it, and pull the plug before you hit US 64. Then make sure the policy matches the lake: liability limits that protect what you own, physical damage that values the boat the way you expect, a navigation area that includes Colorado waters, and towing and wreck removal for the day something goes wrong far from the ramp.
