Colorado Stream-flow Information

The following links give stream flows for many rivers in Colorado. This information can be especially important during runoff season, from April into July, and for tailwaters, where water managers control the flow year-round.  Keep a journal or call local fly shops to get an idea of what a fishable or unfishable flow is for a particular river.
