Williams River Summary

The length of the mainstem is 25 miles and drains a watershed that is 117 square miles. The dominant land cover type in the Williams River watershed, covering 82% of the area is forest. The remaining land cover is comprised of: agriculture (4%), surface water (6%), transportation uses (4%), developed land other than transportation uses (2%), and wetland (1%).

The assessment only noted two swimming holes in the Williams River because the river is relatively shallow in the summer. The noted swimming holes are Rainbow Rocks and Brockway Mills, in Chester and Rockingham respectively. There are three whitewater boating stretches in the Williams River watershed that range from Class II to Class IV whitewater. There are 17 occurrences of plant species and 2 bird species that are of statewide importance in the Williams River watershed. There are four occurrences of natural communities; three shallow emergent marsh communities and one riverside outcrop community in the Williams River watershed.

The upper mainstem Williams River supports healthy populations of wild brook trout, and in some cases, wild brown trout. However, due to high summer water temperatures the trout populations are limited in the lower mainstem Williams River. Atlantic salmon populations are thriving through the entire watershed because of their higher tolerance for warm water temperatures. The Williams River is currently impassable to upstream migrating salmon at Brockways Mills dam and falls. There is excellent spawning, rearing, and holding habitat from the dam to the Connecticut River for the Atlantic salmon; the affect of the dam on the Salmon population is unknown at this time.
