Colorado Parks and Wildlife killed Miramonte Reservoir in SW Colorado about 5 years ago, because someone thought it would be smart to put smallmouth bass in it. They never got any size, and ruined the trout fishery, it's back to being pretty good for trout again, and I hope they learned their lesson. It's not a big reservoir, and only has inflow in the spring from runoff so the logistics were manageable. It was probably the same individual who put smallies in the lower Dolores. I've caught a few, but they were not very big, this summer I intend to try some deeper pools with flies, sounds like fun too me.
