Yes. The “stream bank damage” argument is downright childish. Another example of the childishness of suburban trout fishermen’s associations would be an addition to Colorado regulations, where out-of-state trout fishermen managed to outlaw live bait for kids there. ...shame. Let them stock their eastern suburban backyards with trout, IMO.
The word, overgrazed, is linguistic activism used by environmentalists—a word that can be beaten by proper rudimentary education in agriculture. Pastures need fertilization and seeding, even in drier areas. Soil needs healthy roots to hold it in place and to retain water. Richer pastures do not noticeably deprive aquifers of water.
As for trout, they need rocky streams, and herds of cattle only drink and ford in very small parts of those streams. Trout have coexisted with vast numbers of buffalo, elk, deer and antelope on the ranges. They can coexist with relatively small herds of cattle.
Me...I’ll shoot various ruminants and others, consume some of ‘em, tag ‘em and make coats and rugs out of ‘em. That should make the slick city entertainers of trout happy, but it probably won’t. ;-)
