In our region, the state stocks, but TU volunteers help with the actual putting of fish in the water, so that the fish can be float stocked, not just dumped into one spot. Maybe the OP's chapter could do something like that.

Just to clarify my original post that is exactly what we were doing, we never spent a dime for any fish it was just volunteer work to help with a state stocking program. Our only expense was for float boxes.
