The USGS site is a wealth of information. I'm glad I had a good understanding of it before these apps were available. And I will acknowledge and thank Al for helping me to understand what I was reading from these gauges. I used to always just look at gauge height and that seemed to work. But as Al has suggested in the past I started paying more attention to CFS and it has been very beneficial to understanding the waters I float a lot and what to expect when I get there. Thank you for that Al. Now when my wife says lets go float I can open my app, check the 3 gauges that are close, and have a plan of where we are going in about 10 seconds.
