Mason Valley WMA Access provides multiple entry points to the Walker River and associated ponds (Hinkson Slough, North Pond, Bass Pond, Crappie Pond) with improved boat ramps and facilities.

North Pond features a paved boat ramp, campground, and paved parking, while Bass Pond and Hinkson Slough offer gravel/padded ramps; fishing season runs from the second Saturday in February through September 30th.

The area is located about 75 miles southeast of Reno near Yerington, with well-maintained dirt roads providing access to different water areas, though visitors should check water depth before launching as conditions can vary seasonally.
