Boating & Water Recreation

Big Water and a Mountain Lake

When the weather warms up, Box Elder County heads for the water. Launch a boat on the open water of Willard Bay or paddle the calm surface of Mantua Reservoir in the mountains above Brigham City. Both are just minutes from Brigham City, making it easy to spend the whole day on the water.

Where to Get on the Water


Willard Bay State Park is the county’s biggest playground for boaters, with two marinas, sandy beaches and plenty of room for waterskiing and wakeboarding. Just up Box Elder Canyon, Mantua Reservoir offers a smaller, cooler mountain setting that’s popular with paddlers, anglers and families.

Between the two, you can spend one day pulling skiers across open water and the next paddling a quiet mountain shoreline.

Willard Bay State Park

May–September · Two marinas · Waterskiing & beaches

This 9,900-acre freshwater reservoir is the go-to for boating in Box Elder County. Launch from the North or South Marina, then spend the day waterskiing, wakeboarding or paddleboarding. Sandy beaches and shady day-use areas make it easy to settle in for the afternoon.

Mantua Reservoir

May–October · Mountain setting · Paddling & family fun

Just up Box Elder Canyon, this mountain reservoir offers a boat ramp, a swimming beach and calm mornings that are perfect for kayaks and paddleboards. At about 5,000 feet, it stays a little cooler than the valley on hot summer days.

Before You Go



CLEAN, DRAIN, DRY


Utah requires boats to be cleaned, drained and dried to stop the spread of invasive mussels. Plan for an inspection.

WEAR A LIFE JACKET


Bring a properly fitting life jacket for everyone on board. Check Utah’s boating rules for kids.

CHECK WATER QUALITY


Algal blooms can affect some lakes in late summer. Check for advisories before swimming.

KNOW THE FEES
