Well a quick google answered my question. The Colorado Parks and Wildlife's "Upper Arkansas River Management Implications" states that is has long been "suggested to introduce a large forage item into the Arkansas River biota to boost trout growth and fitness." They decided the pteronarcys californica best fit the bill ... which I reckon is better than some foreign shrimp or such thing. But I find this messing with the ecology of a river for simple human pleasure gain a slippery slope.
It's on page 6.
It is my understanding that prior to the mining pollution, there was a salmonfly hatch on the Arkansas. The quote that you offer does not appear to be inconsistent with this.
