Streams have invisible underground flows connecting channel and forest

Evidence

Even the river, Lookout Creek, doesn’t respect clear boundaries. It tumbles and slides down its main channel, where a dipper rides between pools. But Fred Swanson, a hydrologist here at the Andrews Experimental Forest, has told me stories of another stream, an invisible shadow of Lookout Creek, the hyporheic flow. This is the water that moves under the stream, in cobble beds and old sandbars. It edges up the toe slope to the forest, a wide unseen river that flows beneath the eddies and the splash. A deep invisible river, known to roots and rocks, the water and the land intimate beyond our knowing. It is hyporheic flow that I’m listening for. — Robin Wall Kimmerer, Braiding Sweetgrass, 1086
