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, campgrounds, and paved parking, while Bass Pond and Hinkson Slough offer gravel/padded ramps; check water depth before launching as conditions vary seasonally.

The area is open for fishing from mid-February through September 30, with well-maintained dirt roads providing easy access to different water areas.
