Quick Overview
Merrill is a small Northwoods city on the Wisconsin River in Lincoln County, about 15 miles north of Wausau. It's a gateway to central Wisconsin's lakes, rivers, and forests, and despite its size it has an unusually handy set of dump options, anchored by a 24-hour county fairgrounds station. We've mapped several dump stations in the area, with some of them free. Whether you're paddling the river, fishing the Northwoods lakes, or passing through on US-51, you'll find a place to empty your tanks easily.
The standout option is the Lincoln County Fairgrounds RV dump station in Merrill, which is open 24 hours a day, seven days a week, year-round, and provides potable water for filling your fresh tank. That round-the-clock, all-season access is rare in the Northwoods and makes it the go-to. For state park camping, Council Grounds State Park on the Wisconsin River (N1895 Council Grounds Drive) has a dump for $10 plus a park sticker, though it's seasonal.
For a quick fuel-and-dump stop, the R-Store gas station at N357 Brandenburg Avenue charges $7 with a fuel purchase or $8.50 without (seasonal). The Merrill wastewater treatment facility also accepts RV waste. Around the county, forest campgrounds on the Northwoods lakes and rivers add more options in summer. Never dump on the ground or into the Wisconsin River, which is a treasured recreational and ecological waterway.
The big factor is the season. Central Wisconsin winters are long, cold, and snowy, so the state park and gas-station dumps close seasonally, generally running from late spring through early fall. The fairgrounds dump's year-round, 24/7 operation is the exception. Summer is the prime camping time on the river and lakes, and the Northwoods fall color in late September into October is beautiful. Below you'll find every dump station we've mapped in Merrill, with notes from fellow RVers on fees, hours, and seasonal access.

Merrill is easy central Wisconsin driving, flat to gently rolling through woods and river country with no grades. US-51 is the main route, an expressway running south to Wausau and on to I-39, with WI-64 crossing east-west and WI-107 and WI-17 reaching the surrounding Northwoods. The town is small and easy to navigate, and Wausau just south has full services and RV repair if you need them.
For dumping, the Lincoln County Fairgrounds station (24/7, year-round, with potable water) is the anchor, with Council Grounds State Park and the R-Store gas station as seasonal options. Fuel and groceries are in Merrill and fuller in Wausau. The defining factor is the short, snow-bound season: plan camping for roughly May through October, since the long Wisconsin winters close most facilities. Check Lincoln County for forest campground reservations and the DNR for Council Grounds State Park status.

Before You Go: RV Trip Essentials
Dump stations are only one piece of the trip puzzle. Before you set out for your trip to Merrill, Wisconsin, it's worth taking thirty minutes to check that the basics are in place — the four areas below are where unprepared RVers most often get stung.
Check your RV insurance coverage
A standard auto policy rarely covers a Class A, Class C, or travel trailer the way a dedicated RV insurance policy does. If you're financing a motorhome, lenders typically require comprehensive and collision; full-timers should additionally price in vacation liability and personal belongings coverage. Rates vary widely by state and travel pattern — compare quotes from multiple RV-focused carriers before each season.
Know your roadside assistance options
RV-specific roadside plans tow motorhomes and trailers that regular AAA coverage won't touch — flat beds, mobile mechanics, tire service for duallies, and even emergency lockouts at remote campgrounds. Good plans cover your spouse and trailer even if you're driving a separate vehicle, and some include trip interruption reimbursement if a breakdown costs you a reservation.
Decide about an extended warranty early
Original manufacturer warranties on new RVs typically run 12–24 months — shorter than most buyers realize. An extended service contract (essentially a mechanical breakdown policy) covers the appliances, slides, levelling systems, and drivetrain components that can run $3,000–$10,000 to replace. The time to price one is before the factory coverage expires, not after something breaks.
Set up a travel rewards card for fuel and fees
A no-annual-fee travel or gas rewards card pays for itself on a single month of RV travel. Expect to spend $400–$800 per week combined on fuel, campgrounds, and propane — 3–5% cash back on gas alone covers the next oil change. For bigger trips, a sign-up bonus can offset campground fees for the whole season.

Dump Station Costs in Merrill
Merrill is a cheap and easy place to dump. The Lincoln County Fairgrounds RV dump is the best value, open 24/7 year-round with potable water at minimal or no cost (a true public convenience). Council Grounds State Park charges a $10 dump fee plus the park sticker, and the R-Store gas station is $7 with fuel or $8.50 without.
So your costs run from essentially free at the fairgrounds to about $10 at the state park, all low. The county forest campgrounds are inexpensive too, with the dump included for campers at some. The real consideration is the season rather than the fees: the state park and gas-station dumps close for the long winter, leaving the year-round fairgrounds station as the cold-weather option. To keep costs minimal, use the Lincoln County Fairgrounds dump, which is hard to beat for both price and 24/7 access in the Northwoods.
