Mason Valley WMA Access provides multiple entry points to the 17,742-acre wildlife management area near Yerington, with well-maintained dirt roads connecting to several fishable waters including Hinkson Slough, North Pond, Bass Pond, and the Walker River.

North Pond features an improved boat ramp, paved parking, and designated campsites, while Bass Pond and Hinkson Slough offer gravel and padded boat ramps; fishing season runs from the second Saturday in February through September 30.

Visitors should check water depth before launching as pond depths vary from less than 5 feet to 13 feet, and note that camping and vessel use are restricted during the waterfowl breeding season (February 15 through August 15) in certain pond areas.
