Data Story - Rise and Fall of a River
Lesson
Background The US Geological Survey monitors the flow of many US rivers to track watershed conditions and to understand how rivers respond to weather and climate. The Piscataquis River is a major tributary of the Penobscot River in northern Maine, and is a popular river for fly fishing. The graph shows daily flow rates of the Piscataquis River during 2015. Flow rate (“discharge”) is given in cubic feet per second (cfs). How did the river flow change through the year?
