Here is the map for the Blue River in Oklahoma, USA. This came from a brochure about the Blue River and is apparently somewhat difficult to find. There is also good information in Barry Shrader’s site and Karl Hungus’ site, the latter of which may still contain this same map. I put Hungus together with Shrader last year, and he did some good on the Blue. If you are interested in an interview with Shrader, please look back in my archives as there is a pretty good and insightful interview about the dynamics of the Blue River.
