Motts Run Reservoir is a 160-acre lake located in Spotsylvania County, Virginia that serves as a water supply for Fredericksburg. The steep-sided reservoir features an undeveloped shoreline, making it one of the more scenic lakes in Northern Virginia. The lake is typically quiet and receives light use.

Paddlers can access the water via a boat ramp operated by the Fredericksburg Parks and Recreation Department. The facility offers canoe and kayak rentals, with boats reserved on a first-come, first-served basis. Only electric motors are permitted on the lake, and stand-up paddleboards (SUPs) are not allowed.

The reservoir is open April 1 through October 31, Thursday through Monday, from 7:00 AM to 7:00 PM. It is closed Tuesdays and Wednesdays. Early in the season (April 1-May 26), boat rentals are only available Friday through Sunday. From May 27-October 31, full concession services operate Thursday through Monday.

Amenities include parking, portable toilets, picnic tables, and fishing piers. A nature center, open weekend afternoons from noon to 5:00 PM, features wildlife displays and educational programs. The surrounding 860-acre natural area contains over 4 miles of hiking trails.

Due to its primary function as a drinking water supply, swimming is prohibited. A daily or seasonal permit is required for boating. In case of questionable weather, visitors should call ahead as the facility may close early.

Wildlife observers may spot beaver lodges along the shoreline. The lake's underwater topography is notably steep and deep, having been scraped clean of structure during its construction. The undeveloped shoreline and surrounding forest create a peaceful paddling environment within easy reach of Fredericksburg.
