Tapeats is fed by Thunder River Springs and Tapeats Spring, so flows will be relatively similar for most of the year. Some writers state that it is much higher during the spring. During heavy rains the flows can be much higher. This authors very rough guess on the flow is that it is around 40 or 50 cfs, which is plenty for the narrow canyon.
