Table of Contents
In recent years small amounts of placer gold have been mined from the lower Chowchilla River west of Raymond in western Madera County. The gold has been recovered by several small- to medium-sized floating suction dredges, which consist of pontoons that carry suction pumps and gold-recovery equipment. The river gravels range from 10 to as much as 35 feet in depth. This area was first placer-mined during the gold rush, when the Grub Gulch district to the northeast was active.
