Conclusion
Mayflies, caddis flies, and stoneflies are an important factor in the ecology of City Creek. They are a key food source for trout and birds, as well as an indicator of good water quality. The presence of many of these species shows that City Creek is healthy. Comparing the abundance of these organisms to those in Emigration Creek you can see that Emigration Creek is unhealthy since it contains fewer of these organisms. A big reason for this could be the periodic flood pulses created by urban storm drain run-off. City Creek has these periodic flood pulses, but the run-off is much cleaner, coming from an undisturbed watershed. As well as playing a big part in the food web, and indicating water quality, these organisms even have uses for humans. Many fishermen use them as bait. As you can see, mayflies, caddis flies, and stoneflies play a major role in the ecology of City Creek.
