Reading and Interpreting River Level Data (CFS and Feet)
Understanding river level data is crucial for anyone planning activities on or near Oregon’s rivers. River level data is typically presented in two key units: Cubic Feet per Second (CFS) and Feet; CFS measures the volume of water flowing past a specific point in the river per second. One CFS is equivalent to approximately 7.48 gallons of water flowing per second. A higher CFS value indicates a greater volume of water and potentially faster currents. Feet refers to the height of the water surface above a predetermined reference point at the gauge location.
Interpreting CFS and feet readings requires considering the specific river and location. Each river has its own unique characteristics, and what constitutes a “high” or “low” level can vary significantly. It’s important to consult historical data and local knowledge to understand the typical range of CFS and feet values for a particular river. Also, consider that 100 CFS is equivalent to 45,000 gallons per minute. Analyzing both CFS and feet readings together provides a more complete picture of river conditions. For example, a high CFS reading combined with a high feet reading indicates a river that is both deep and flowing rapidly, potentially posing hazards for recreational activities.
