...then maybe some will make it back up to Lake Sutherland, but it is going to be a while until they can get past the dams. Out migrating smolts will have an increasingly easy time as the dams come down. Wild fish can't be caught in the river/streams in the basin so a size restriction and a fish trap/ladder for returning adults along with a size restriction or a partial season closure on the lake during the spawn time should be workable options that would allow the lake to remain open.
