Burnlet

[…] streams often mere burnlets, where a 3-lb. fish has barely room to turn [around].

[...] sky-reflecting pools like tarnished silver buckles, and winding burnlets that wandered down from the hills to join the broad loop of the river that flowed out through Mhoin Mhor to the sea.

[...] water-meadows, of great outcropping rocks as big as houses, and long sweeping grassy aprons scored by burnlets innumerable.
