Moon, seven miles is quite a distance. In a lot of small streams, if you search along a seven mile length, you would find pools, even when most of the streambed is dry. This is not the case with your stream? Creek chubs are among the most upstream inhabitants of many stream systems, resembling green sunfish in their ability to make do with the remnants of streamflow during droughts. But upstream movement is common to many minnows-in-spawning time.
