There's nothing not to agree with here, but the Rieter example is not all that appropriate. The Reiter reach of the stream is not open to summer running until the hatchery reaches its brood stock goals (usually 500 fish). Thats why the reach doesn't usually open until August 1 while the rest of the river opens June 1. By the time the Reiter reach opens, the hatchery has its fish and can spawn no more because of their budget. Remaining fish are either caught or spawn in the river; the latter is not desirable.

Although kind of dumb and desperate, chasing fish out of the hatchery creek doesn't really harm the resource.
