Monksville Reservoir, located in Ringwood, New Jersey, offers paddlers a 505-acre expanse of water surrounded by forested hills. The horseshoe-shaped reservoir spans approximately three miles from end to end and features an average depth of 43 feet, with a maximum depth of 90 feet.

Three primary access points serve paddlers: the North Boat Launch, South Boat Launch, and Beech Road Launch. The North Launch provides a wide paved ramp suitable for trailers, while the South Launch offers kayak and paddleboard rentals. Beech Road Launch features a long dock, though it requires a short carry from the parking area.

The reservoir is bisected by the Route 511/Greenwood Lake Turnpike bridge. South of the bridge lies the main body of water, curving down to the Monksville Dam. North of the bridge, paddlers can explore an area of submerged trees, adding interest to the paddle. The Wanaque River feeds into the northeast corner of the reservoir, allowing for a short upstream excursion before it becomes too shallow.

Wildlife sightings may include swans, beavers, cormorants, and various bird species such as great blue herons, wood ducks, and cedar waxwings. The surrounding Long Pond Ironworks State Park offers hiking trails and historic sites related to the area's ironworking past.

Paddlers should be aware of a few safety considerations. The dam area can experience sudden water movements, so it's advisable to maintain distance. Power lines cross the water in some areas. Weather conditions, particularly wind, can change rapidly, especially in the wider southern portion of the reservoir.

Monksville Reservoir is open to paddle craft, sailboats, and power boats under 10 hp. Facilities include portable toilets at the launches, though their condition may vary. The reservoir's clean water and undeveloped shores provide a peaceful paddling experience, with fall foliage offering particularly scenic views.

For a full circumnavigation of the reservoir, allow 3-4 hours. The area north of the bridge, with its submerged forest, is a highlight for many paddlers. Overall, Monksville Reservoir offers a mix of open water and sheltered paddling suitable for various skill levels, all within an hour's drive of New York City.
