The lower Ruby is a western tailwater. She has prolific and predictable hatches of caddis, mayflies, and stoneflies all providing food for its healthy trout population. Near the dam, you will catch more rainbows than browns on small Beatis and Caddis nymphs, while the lower stretches are home to mostly brown trout. The lower Ruby is home to larger trout than the upper river that also love to eat dry flies! The Ruby below the dam has a short canyon section that has more large rocks and boulders and good pocket water  As The Ruby flows through the valley floor it enters more cattle ranching country with curvy grassy banks. In many pools it fishes like a spring creek with lots of overhanging willows and cut banks. Its easily-waded gravel bottom is perfect for the wade angler. These trout make aggressive surface strikes and are hard fighting all the way to the net.
