A perennial stream is one which flows continuously all year. Some perennial streams may only have continuous flow in segments of its stream bed year round during years of normal rainfall.
Blue-line streams are perennial streams and are marked on topographic maps with a solid blue line.

Famous quotes containing the words ephemeral and/or streams:
“The season developed and matured. Another year’s installment of flowers, leaves, nightingales, thrushes, finches, and such ephemeral creatures, took up their positions where only a year ago others had stood in their place when these were nothing more than germs and inorganic particles. Rays from the sunrise drew forth the buds and stretched them into long stalks, lifted up sap in noiseless streams, opened petals, and sucked out scents in invisible jets and breathings.”
—Thomas Hardy (1840–1928)
“The wilderness experiences a suddent rise of all her streams and lakes. She feels ten thousand vermin gnawing at the base of her noblest trees. Many combining drag them off, jarring over the roots of the survivors, and tumble them into the nearest stream, till, the fairest having fallen, they scamper off to ransack some new wilderness, and all is still again.”
—Henry David Thoreau (1817–1862)
