Understanding Discharge (CFS) on Clear Creek
Streamflow volume is measured in Cubic Feet per Second (CFS). One cubic foot is roughly equivalent to a basketball full of water (~7.48 US gallons). When the gauge on Clear Creek reads 500 CFS, it means that 3,740 gallons of water pass the monitoring transect every second.
Discharge is calculated by the USGS using a calibrated stage-discharge rating curve that relates the physical height of water above a fixed gauge datum to measured cross-sectional flow velocities.
How to Read Flow Curve Trends
Hydrograph slope indicates whether Clear Creek is charging from runoff or receding into clear, stable baseflows.
Rising Limb (Surging)
Runoff from recent rainfall is entering the river channel. Expect murky water, rising velocities, floating debris, and submerged obstacles.
Hydrograph Crest (Peak)
Peak discharge has arrived at the gauge. Hydraulic features, standing waves, and current speeds reach their highest intensity.
Falling Limb (Receding)
Water clarity begins recovering as sediment settles. Flow transitions toward predictable, enjoyable paddling baseflows.
Seasonal Streamflow Patterns for Clear Creek
Rivers across Pennsylvania follow distinct seasonal hydrograph cycles. In spring, melting snowpack or prolonged rainstorms generate high-volume peak flows suitable for whitewater rafters and experienced kayakers. By mid-to-late summer, flow stabilizes into warm baseflow conditions ideal for tubing and family paddling.
