They call the Green River hatchery the Toutle river salmon hatchery, and the Mt Margaret Lakes are public (vs. Tradedollar, Fawn, Hanford which or on private land). Who knows if this designation would effect fishing, but I've just seen other examples of protective designations shutting down or being used as an excuse to shut down legitimate recreation, or it makes any improvements more difficult. Could the risk be worth it to stop a mine--maybe.
