As expected, canopy coverage appears to be inversely proportional to channel width. Sheepscot River tributaries have much less canopy coverage than several other Maine salmon rivers, even though their widths were similar or larger. Lack of riparian canopy can increase fluctuations in water temperature and be detrimental to salmonids. Mainstems and tributaries are listed separately, and then sorted by mean stream width.
