Attention river paddlers! Would you like to receive an e-mail or text message when your favorite river reaches its ideal level? The U.S. Geological Survey has a new system in place to do just that. USGS WaterAlert will let you select the monitored river from a map and subscribe to different thresholds such as above or below a certain level, or inside or outside of a given range for either or both river height or discharge. So you will never miss a paddling opportunity again!
