The Stamp Committee invests about $180,000 annually for this rearing project. The two million yearling-sized fish reared there are trucked downriver for release below the Sacramento-San Joaquin Delta. The Stamp Program has also contributed regularly to this operation through purchase of equipment needed to implement the rearing program successfully.
