It is so nice to have access to flow rates before you make that drive. I have found two things to be indispensible lately. Wonder maps and USGS subscriptions. Using wonder maps, it’s easy to find a gauge close by to your proposed trip. And with a subscription to the gauges you find getting up dates is a snap.

I am making a trip to the Neches this weekend. The link above will help provide flow rates and other information from a site close by my paddling locale.
