Mason Valley WMA Access provides multiple boat ramps and fishing access points along the Walker River and associated ponds (North Pond, Bass Pond, Hinkson Slough, Crappie Pond).

North Pond features an improved paved boat ramp with campsite facilities and parking, while Bass Pond and Hinkson Slough offer gravel and padded ramps; note that water depths vary seasonally and may be shallower than expected.

Fishing season runs from the second Saturday in February through September 30th, with designated camping areas available at North Pond.
