As in the brook, the many small animals which live in the river must adapt to a strong current. Fish are streamlined here and powerful swimmers. Insects attach themselves to rocks or seek the calm of quiet pools. These small insects are food for swallows, sandpipers, kingbirds and fish. The fish in turn provide sustenance for the heron, kingfisher or mink.
Deer visit quiet pools at dusk and dawn.
Beavers use it as a travel way. In summer male mayflies engage in swarming flights inches above the water. The river is a haven for life.
