Niff, what you are saying is clearly the case today. What I'm wondering is whether, going back nearly a century to when the postcard was published, is it possible that very few or zero cities other than Duluth were located on trout streams? It seems kind of crazy. Postcards were known to exaggerate, but maybe this one is making a joke if the claim is that ridiculous.

Here is the card, published by Arrowhead Printing Company of Duluth. It was never mailed, so it's not dated. Big Chester was built in 1924, so the postcard is more recent than that.

So yeah, there are probably numerous examples, but taking the last one Ramos offered should be proof enough.

According to Wikipedia, Great Falls was incorporated on Nov. 28, 1888. Members of the Lewis and Clark Expedition caught numerous Westslope cutthroat trout there in 1805,  Paleo-Indians and Piegan Blackfoot Indians probably caught trout there prior to that.

The Missouri River runs right through the middle of the city limits and unless there was some weird anomaly a half century or more ago trout must have been there for the fishing when that lying little Duluth postcard came out.

"Not quite as pretty as the Cascades," writes Margaret in 1904.

I'm sure Margaret must have been some kind of beauty queen.
